• Per his profile on MLB.com, right-hander Trevor Hildenberger has been released by the Giants. Hildenberger, who signed a minor league deal with the Giants back in December, last appeared in the majors in 2021 with the Mets. In that two appearance stint he allowed four runs on three hits and three walks in 2 1/3 innings while notching four strikeouts. Prior to his stint with the Mets, Hildenberger had been part of the Twins bullpen from 2017-2019 after the club selected him in the 22nd round of the 2014 draft. As a member of the Twins, Hildenberger pitched to a 5.35 ERA with a 4.08 FIP in 131 1/3 innings of work. In the minors, Hildenberger sports a career 4.43 ERA in 85 1/3 innings at the Triple-A level.
• The Dodgers recently released right-hander Rubby De La Rosa according to Chris Hilburn-Trenkle of Baseball America. De La Rosa, 34, has amassed 421 1/3 innings in the big leagues across seven seasons, but hasn’t pitched in the majors since 2017. With a 4.49 ERA (91 ERA+) and 4.55 FIP in the big leagues, De La Rosa headed to Japan to pitch for the Yoimuri Giants from 2019-2022 before signing a minors deal with the Dodgers back in February. With a 2.53 ERA in 124 1/3 innings of work out of the bullpen in Japan, it’s certainly possible another club could be interested in giving De La Rosa a shot on a minors deal.
• The Mariners recently signed left-hander Rob Kaminsky and right-hander Braden Shipley to minor league deals, per Hilburn-Trenkle. Kaminsky has five career games in the big leagues under his belt, all of which came during the 2020 season with the Cardinals. The lefty pitched to a solid 1.93 ERA over 4 2/3 innings of work, though he has amassed just 41 2/3 innings of work in the minor leagues since. Shipley, meanwhile, has 100 career innings in the big leagues across the 2016-2018 seasons with the Diamondbacks, though he struggled to a 5.49 ERA over those 26 games (14 starts). A former first-round draft pick, Shipley returns to the Mariners after pitching for their Double-A affiliate last season, with a 3.79 ERA in 54 2/3 innings of work.

De La Rosa, 34 next month, has spent the past few seasons in Japan, and hasn’t pitched in the big leagues since 2017. Last year, he tossed 38 1/3 innings of relief for Yomiuri in Japan, working to a 2.58 ERA. That was his fourth season with the team, and he’s been a highly effective reliever over that period, finishing with a combined 2.53 ERA over 124 1/3 innings.

This move marks something of a homecoming for De La Rosa, who signed with the Dodgers out of the Dominican Republic back in 2007. The right-hander was well regarded coming through the minors, and made Baseball America’s top-100 prospects prior to the 2011 season. After a promising rookie year (3.71 ERA over 60 2/3 innings), the Dodgers shipped him to the Red Sox as part of the deal for Carl Crawford, Adrian Gonzalez and Josh Beckett in 2012.

De La Rosa never did deliver on his promise, struggling in Boston after returning from Tommy John surgery before being traded to the Diamondbacks in 2014. He spent a couple of seasons in Arizona, but after working to a 4.59 ERA over 247 innings, De La Rosa required a second Tommy John surgery and the Diamondbacks let him go. They would re-sign him to a two-year minor league pact, but he’d never make it back to the majors.

De La Rosa’s starting days are probably behind him, but he’ll add a bit of minor league bullpen depth for the Dodgers. Even dating back to his big league days in the last decade he was long speculated as someone who could find a lot more success in the bullpen, and he certainly did in Japan, so it’ll be interesting to see how he fares in his first season back in the US since 2019.

Yomiuri Giants (77-64-2 record in 2019):

• Hisashi Iwakuma, RHP: Perhaps the most well-known player on this list, Iwakuma was a rock in the Mariners’ rotation from 2012-16 before shoulder injuries interrupted a very strong MLB run. He signed with NPB’s Giants in the 2018-19 offseason but was only able to throw two minor league innings last year. Now 39, he’ll take another shot at a return in 2020.
• Gerardo Parra, OF: The man who brought “Baby Shark” to Nationals Park and celebrated a World Series win last October took an early free-agent deal with the Giants back on Nov. 20. The 33-year-old batted .250/.300/.447 with the Nats last year.
• Rubby De La Rosa, RHP: Once considered to be among the game’s top pitching prospects, the now 31-year-old De La Rosa had a decent run with the Red Sox and D-backs from 2014-17 before injuries derailed his career. He made his NPB debut with the Giants last year, pitching to a 2.25 ERA with a 32-to-5 K/BB ratio in 24 innings.
• Angel Sanchez, RHP: Pirates fans are excused if they don’t remember Sanchez’s brief 12-inning cup of coffee from the 2017 season. Sanchez, now 30, had a very promising 2015 between Double-A and Triple-A before his 2016 season was lost to Tommy John surgery. He’s spent the past two years with the KBO’s SK Wyverns, including an impressive 2.62 ERA with 8.1 K/9 against 2.3 BB/9 in 165 innings in 2019.
• Thyago Vieira, RHP: The 26-year-old Vieira was an intriguing prospect with the Mariners and White Sox due to his huge fastball velocity, but he was hit hard in 25 2/3 MLB frames and in the upper minors. This will be his first season in Japan.

Yokohama DeNA BayStars (71-69-3):

• Jose Lopez, 1B: Yes — it’s that Jose Lopez. An All-Star second baseman with the Mariners way back in 2006, Lopez is now 36 years old and a seven-year veteran in NPB. In two seasons with the Giants and five with the BayStars, he’s a .276/.317/.500 hitter with 186 home runs.
• Spencer Patton, RHP: The 32-year-old hasn’t pitched in the big leagues since 2016 and has just a 6.26 ERA in 54 frames between the Rangers and Cubs. But Patton has made a name for himself with the BayStars, for whom he pitched to a combined 2.64 ERA in 116 innings from 2017-18. He had a down year in ’19 and will be looking for better health and better results in 2020.
• Edwin Escobar, LHP: Still just 28, Escobar hasn’t pitched in the Majors since a 2016 cameo with the D-backs. That’s due largely to the success he’s found in Japan, where he’s logged a 3.36 ERA with 9.5 K/9 and 3.4 BB/9 in three seasons out of the BayStars’ bullpen.
• Tyler Austin, OF: Austin has shown plenty of power in parts of four MLB seasons, but his strikeouts have limited him to a .219/.292/.451 overall batting line. The former Yankees prospect will be suiting up for the first time in NPB this season.
• Neftali Soto, INF/OF: The 31-year-old Soto saw all of 44 MLB plate appearances with the Reds in 2013-14, but he’s hit like a star in Japan. In two seasons with the Yokohama club, he’s batted .288/.355/.594 with 84 home runs inn 1043 plate appearances. He’ll be a free agent next year and could potentially draw some MLB interest.

Hanshin Tigers (69-68-6):

• Kyuji Fujikawa, RHP: The now 39-year-old Fujikawa never took off after signing with the Cubs for the 2013 season. He returned to NPB in 2016 and has regained his status as a high-end reliever with his original club, the Tigers. Fujikawa whiffed 83 hitters and posted a 1.77 ERA in 56 innings last year.
• Kosuke Fukudome, OF: Another former Cub, Fukudome is still chugging along at 43 years old. He hit .256/.347/.394 in 403 plate appearances with the Tigers last season — his 16th in NPB.
• Justin Bour, 1B/DH: Bour blasted 92 home runs in a six-year run with the Marlins, Phillies and Angels, but he never hit much upon leaving Miami. His power should play well in his NPB debut this year, and hopefully his “Bourtobello Crushroom” nickname catches on there (even though Bour told Sports Illustrated he’s never actually been called by that nickname, it still appears on his Baseball-Reference page).
• Jon Edwards, RHP: Edwards, 32, has seen MLB time with the Rangers, Indians and Padres but never cemented himself as a steady contributor. He boasts a 3.08 ERA and 12.4 K/9 in parts of four Triple-A seasons, however. This will be his NPB debut.
• Onelki Garcia, RHP: Garcia, 30, has just 7 1/3 MLB innings to his name and will return to the Tigers for a second season after struggling to a 4.69 ERA in 103 2/3 frames last year. He did post a strong 2.99 mark with the Chunichi Dragons in 2018.
• Jefry Marte, 1B/3B: Marte never found his stride in parts of four seasons with the Tigers or Angels from 2015-18, but he posted a .284/.381/.444 slash in his debut effort with Hanshin last season.
• Jerry Sands, OF: The 32-year-old Sands had a journeyman career in the U.S. but hit at star levels in the Korea Baseball Organization over the past two seasons: .306/.391/.574. He signed with Hanshin this winter and will be making his NPB debut.

Hiroshima Toyo Carp (70-70-3):

• Kris Johnson, LHP: Johnson, 35, barely got a look with the Pirates or Twins, but he’s been one of Japan’s best pitchers over the past half decade. In five seasons, all with the Carp, he has a combined 2.54 ERA with averages of seven strikeouts and three walks per nine innings.
• DJ Johnson, RHP: This will be the first NPB season for Johnson, who posted a 4.88 ERA in 31 2/3 innings with the Rockies over the past couple of seasons. As an undrafted player who has also spent time on the indie circuit, the 30-year-old Johnson is cultivating quite the unique baseball career.
• Tayler Scott, RHP: The second South African-born player to make it to the big leagues — Gift Ngoepe was the first — Scott was hit hard in 16 1/3 frames between the Mariners and Orioles last year. However, the 28-year-old also tossed 16 frames with just one run allowed and a 21-to-3 K/BB ratio with the Orioles’ Triple-A club in ’19.
• Jose Pirela, OF: Pirela hit well in a half season with the Padres back in 2017, but he’s struggled in the Majors outside that run. He was never able to win the second base gig in San Diego and was lost in the shuffle of their crowded outfield mix. Pirela brings a career .257/.308/.392 MLB slash to his debut season in Japan, but he’s a .311/.362/.493 hitter in Triple-A.

Chunichi Dragons (68-73-2):

• Dayan Viciedo, 1B: White Sox fans surely remember “The Tank” from his 2010-14 stretch with the South Siders, but he never blossomed into the star they hoped he could. Vicideo hit .254/.298/.424 in just shy of 1800 MLB plate appearances, but he’s a .303/.372/.502 hitter in four seasons as a Dragon.
• Moises Sierra, OF: Speaking of former White Sox outfielders, Sierra’s run with the ChiSox was much more brief than that of Viciedo. He played 83 games there and 207 total in the big leagues from 2012-18, hitting .235/.287/.362 in the process. Sierra posted outrageous numbers in the Mexican League last year (.355/.464/.572) and will make his NPB debut in 2020.
• Enny Romero, LHP: Romero pitched quite well for the 2017 Nats but has otherwise struggled in the Majors. He spent most of last season in the Dragons’ rotation, pitching to a 4.26 ERA through 116 1/3 frames.
• Zoilo Almonte, OF: The 30-year-old Almonte never caught on with the Yankees despite a long look in their farm system, but he’s broken out with the Chunichi club in NPB. In two prior seasons, Almonte is a .323/.372/.491 hitter.

Tokyo Yakult Swallows (59-82-2):

• Nori Aoki, OF: Aoki may be 38 years old, but he’s still a productive hitter. In 565 plate appearances with the Swallows in 2019, he batted .297/.385/.442 with 16 long balls. That’s more power than he showed in MLB, but his six-year run in the Majors was still quite solid: .285/.350/.387, 10.5 WAR.
• Alcides Escobar, SS: Aoki’s former Royals teammate will join him for his debut NPB campaign once play resumes in two weeks. The 33-year-old Escobar’s bat tailed off dramatically in his final big league seasons, but he’s a former All-Star, Gold Glove winner and World Series champion.
• Gabriel Ynoa, RHP: A longtime Mets farmhand, the 27-year-old Ynoa never found much success in the Majors (5.39 ERA in 163 2/3 innings). Ynoa soaked up 110 innings for a disastrous Orioles pitching staff in 2019, but he’ll hope to make more of an impact in his NPB debut.
• Matt Koch, RHP: Koch, 29, never found his footing in four years with the D-backs or even in Triple-A, but he threw well up through the Double-A level in his career.
• Scott McGough, RHP: The 30-year-old McGough has just 6 2/3 innings in the Majors, all with the 2015 Marlins, but he was sharp for Yakult in 2019, pitching to a 3.15 ERA with nearly a strikeout per frame in 68 2/3 innings of relief.
• Albert Suarez, RHP: Once a Rule 5 pick by the Giants, Suarez also saw some time with the Yakult club last season, logging a 1.54 ERA in 17 2/3 frames. He also spent time with their minor league club, but he’ll hope to establish himself further in 2020.
• Ryota Igarashi, RHP: The 41-year-old Igarashi’s time with the Mets, Yankees and Blue Jays in 2010-12 was ugly, but he’s been a consistently strong bullpen presence in a whopping 17 NPB seasons. Last year’s 2.98 ERA in 42 1/3 frames was a near-match with his 2.93 career mark, although his 5.1 BB/9 mark was a bit of a red flag.

We’ve seen foreign stints help spur big league revivals from quite a few players. Eric Thames, Miles Mikolas, and Chris Martin are among those that played significant roles in the 2019 MLB campaign. Whether any of the players covered below will do so remains to be seen, but there’s certainly a path.

We started by looking at position players and pitchers in South Korea’s Korea Baseball Organization (KBO) before turning to the hitters of Japan’s Nippon Professional Baseball (NPB). Remember, teams in these leagues face limits on the number of non-native players they can carry on a roster. That creates a lot of pressure to secure big production from those roster spots, which often spurs mid-season change.

Here’s a 2019 wrap on the NPB’s hurlers from abroad …

• The Saitama Seibu Lions slugged their way to the best record in the Japan Pacific League, but they got some of their best innings from imported pitchers. Former Dodgers and Athletics righty Zach Neal turned in 100 1/3 innings of 2.87 ERA ball after spending some time with their minor league affiliate early on. He could be eyeing a return to the Majors, though a 4.6 K/9 rate in Japan is a red flag even if it’s accompanied by a pristine 1.3 BB/9 mark. Righties Kyle Martin and Deunte Heath, who had quite brief stints with the Red Sox and White Sox, respectively, helped the Lions as well. Martin notched a 3.67 ERA in 41 2/3 innings (albeit with 28 walks), while Heath chipped in 31 1/3 innings of 3.73 ERA ball and averaged 9.8 K/9 against 4.0 BB/9.
• Mariners fans surely remember Cuban-born lefty Ariel Miranda, who started 40 games for them from 2016-18. Now 30, Miranda tossed 86 innings for the Fukuoka Softbank Hawks and notched a respectable 4.19 ERA in a hitter-friendly league, though he carried an unsightly 58-to-48 K/BB ratio. Dutch righty Rick van den Hurk hasn’t pitched in the Majors since 2012, having carved out a career between the KBO and NPB. He only pitched 17 2/3 innings for the Hawks this season but turned in a 3.12 ERA and a terrific 22-to-2 K/BB ratio. Given his track record there — 3.50 ERA in nearly 500 NPB innings — the 34-year-old could be in Japan to stay. The Hawks also enjoyed 57 2/3 innings of 3.90 ERA ball from Japanese-born southpaw Tsuyoshi Wada, who was with the Cubs from 2014-15 before returning to Japan. At 38 years of age, he’s still chugging along.
• Former Twins righty Alan Busenitz and former Indians righty Frank Herrmann formed a dominant setup combo for the Tohoku Rakuten Golden Eagles. Busenitz chipped in 51 frames with a 1.94 ERA with 7.9 K/9 against 3.5 BB/9. Herrmann’s 3.04 ERA and 49-to-16 K/BB ratio in 47 2/3 innings hardly went unnoticed, either. Herrmann will turn 36 early next season, but Busenitz is still just 29.
• The Hokkaido Nippon Ham Fighters didn’t benefit much from former big leaguers, as right-hander Johnny Barbato struggled through 32 innings. Avid Indians fans may remember right-hander Toru Murata, who pitched 3 1/3 innings for the Tribe in ’15 after spending several years in their minor league system. He chipped in 34 innings with a 3.18 ERA but walked nearly as many hitters (21) as he struck out (22). Former Cubs righty Justin Hancock tossed seven innings but was hit hard. Padres diehards may remember minor league righty Bryan Rodriguez, who tossed 91 1/3 innings of 3.25 ERA ball for the Fighters.
• Left-hander Andrew Albers, formerly of the Twins and Mariners, was dominant for the Orix Buffaloes in 2018 but took a step back with a 5.83 ERA in in 63 1/3 innings. The Buffaloes, however, received a seventh strong season from perhaps forgotten Cardinals righty Brandon Dickson, who posted a 3.03 ERA in 35 2/3 frames and has racked up 856 innings of 3.32 ERA ball since first signing with the Buffaloes back in 2013. Orix also picked up former Pirates prospect Tyler Eppler prior to the 2019 season, and after spending some time with the Buffaloes’ minor league club, he emerged with a 4.02 ERA, 7.2 K/9 and 2.6 BB/9 in 31 1/3 innings.
• The 2019 Yomiuri Giants received innings from four former big league pitchers: Taylor Jungmann, Rubby De La Rosa, Scott Mathieson and Ryan Cook. Jungmann struggled to an ERA just over 6.00 in 44 1/3 innings, while De La Rosa fared best (2.25 ERA in 25 innings). Mathieson, now 35, was limited to 22 2/3 innings of 4.37 ERA ball but has been a consistently impressive presence in the Giants’ bullpen since 2012 (2.46 ERA, 54 saves in 431 frames). Cook tallied just 15 innings and surrendered eight runs.
• Lefty Edwin Escobar’s biggest claim to fame in affiliated stateside ball might’ve been being included in a trade for Jake Peavy, but the 27-year-old has become a force in Japan. In his third season overseas, he turned in 75 1/3 innings of 2.51 ERA ball with 10.5 K/9 and 2.9 BB/9 for the second-place Yokohama DeNa BayStars. Former Cubs righty Spencer Patton took a step back after a dominant 2018 with the BayStars, tossing 36 2/3 innings but posting a 5.15 ERA. He did rack up 45 punchouts in that time. And former Nats lefty Sammy Solis made a brief 2019 cameo with the Yokohama club as well, tossing 4 1/3 innings with one run allowed.
• Right-hander Randy Messenger, of mid-2000s Marlins/Giants/Mariners fame, has become one of NPB’s best starters but struggled a bit in his age-37 season (4.67 ERA in 79 innings). But with more than 1600 innings of 3.13 ERA ball in a decade’s worth of time in Japan, he’s left a legacy with the Hanshin Tigers and been compensated handsomely for his efforts. The Tigers also received 103 2/3 innings of 4.69 ERA ball from righty Onelki Garcia, who tossed a combined 7 1/3 innings between the Dodgers and Royals in MLB. Hanshin was also a who’s-who of former Cubs, with righties Pierce Johnson, Kyuji Fujikawa and Rafael Dolis logging significant time. Johnson was brilliant, notching an immaculate 1.38 EA with 14.0 K/9 against 2.0 BB/9 in 58 2/3 frames. Fujikawa (1.77 ERA) and Dolis (2.11 ERA) split closing duties and combined for 35 saves in 111 1/3 innings (both split almost evenly).
• Former big league righties Casey Lawrence (Mariners) and Johnny Hellweg (Brewers) made extremely fleeting appearances with the Hiroshima Carp, who boasted perhaps the most impactful foreign pitcher in the league: lefty Kris Johnson. The former Twins/Pirates hurler has been flat-out dominant in five seasons with the Carp, totaling 756 1/3 innings with a 2.54 ERA, 7.0 K/9 and 3.0 BB/9 since making the jump. He’ll turn 35 next week, but it’s perhaps worth noting that the former Sawamura Award winner’s record contract is expiring.
• Remember situational lefty Enny Romero? He’s not only starting games for the Chunichi Dragons, he’s doing so fairly well. In 116 frames this year, he posted a 4.26 ERA with 8.1 K/9 against 4.3 BB/9. Fellow southpaw Joely Rodriguez, who spent parts of two seasons with the Phillies, overwhelmed NPB hitters with a 1.64 ERA, 11.5 K/9 and 2.1 BB/9 in 55 2/3 frames out of the Dragons’ pen. Even Daisuke Matsuzaka — yes, that Daisuke Matsuzaka — tossed 5 1/3 innings with the Dragons at the age of 39, but he didn’t fare well. To this point, however, he’s announced no plans to retire.
• Lastly, the Yakult Swallows had five former big leaguers suit up for them: righty David Buchanan, right-hander Scott McGough, southpaw David Huff, righty Ryota Igarashi (blast from the past!) and right-hander Albert Suarez. Buchanan paced the group at 99 2/3 innings, though his 4.79 ERA wasn’t much to behold. McGough notched 11 saves and a 3.15 ERA, however, while Huff continued his strong overseas career with a 3.97 ERA. Igarashi is still going strong with a 2.98 ERA at age 40, and Suarez yielded just three runs in 17 2/3 innings.

De La Rosa underwent Tommy John surgery in August 2017, and then turned a two-year minors deal with Arizona that offseason.  The agreement allowed the D’Backs to retain De La Rosa’s rights while he spent all of 2018 rehabbing, with an eye towards being fully healthy this season.

Thus far, De La Rosa seems to be both healthy and effective, judging by his 2.49 ERA, 4.14 K/BB rate, and 12.1 K/9 over 21 2/3 relief innings for Triple-A Reno.  Piecoro also notes that the right-hander is again throwing a high-90s fastball, yet despite this apparent success and the overall middling results posted by Arizona’s bullpen, De La Rosa doesn’t appear to be in the Diamondbacks’ plans.

De La Rosa has a significant injury history that includes two Tommy John procedures and a stem cell treatment on his elbow, though he achieved some decent success in appearing in parts of seven big league seasons with the Dodgers, Red Sox, and D’Backs from 2011-17.  Over 421 1/3 career innings (starting 70 of 98 games), De La Rosa posted a 4.49 ERA, 2.27 K/BB rate, 48 percent grounder rate, and 7.6 K/9.

De La Rosa, 29 next March, battled UCL issues in 2016 but elected to undergo stem cell therapy rather than a second Tommy John procedure. The stem cell treatment looked to have done the trick at one point this past season, as De La Rosa turned in excellent numbers across three minor league levels (mostly Triple-A) before returning to the Diamondbacks in late June. Unfortunately, he’d toss just 7 2/3 innings before going back on the shelf and ultimately going under the knife once again.

A former top prospect, De La Rosa has yet to establish himself as a regular rotation member in the big leagues, but many have wondered how he’d fare as a full-time reliever over the course of his big league career. In this past season’s brief sample, he averaged a hearty 97.1 mph on his fastball, lending credence to the notion that he could function as a power arm out of the ’pen if he ditched his changeup and went with a pure fastball/slider combination. De La Rosa has long fared better against right-handed opponents and could become overpowering against them if his stuff plays up in a short-relief role.

The D-backs won’t be able to gauge that anytime in the near future, of course, but De La Rosa will be a name to keep an eye on when his elbow is (hopefully) healed up for the 2019 season — his age-30 campaign.

It’s obviously discouraging news for the 28-year-old De La Rosa, who battled elbow issues in 2016 and underwent stem cell therapy last September in an effort to avoid a second Tommy John procedure. Those elbow concerns led the D-backs to non-tender De La Rosa last winter, but he re-upped with the Snakes on a minor league deal shortly thereafter.

De La Rosa missed some time earlier this season, but he ultimately worked his way back to the Majors after tossing 24 1/3 strong innings of work in the minors as he ramped up. He’d appear in just nine games this season, though, totaling 7 2/3 innings with a 4.70 ERA before again landing on the disabled list. He’ll now be sidelined for the remainder of the 2017 season and could conceivably miss all of the 2018 campaign given the timing of the operation and the fact that this is his second time going through the procedure.

Arizona picked up Hernandez through the Rule 5 draft, plucking him from the Rays and then managing to secure his rights despite letting him into only 22 MLB games. The youngster understandably didn’t hit much; he had never previously played above the Class A level.

Now nearing his 24th birthday, Hernandez will either be traded or exposed to waivers. Though his calling card is his defensive work behind the dish, he’ll obviously need to show some life with the bat to make it back to the majors. Through 156 plate appearances at Double-A this year, Hernandez carried a sluggish .197/.263/.352 batting line.

De La Rosa had Tommy John surgery as a prospect, but there was some fear in 2016 that he’d require a second TJ operation due to the aforementioned elbow troubles. As a means of avoiding that fate, the 27-year-old underwent stem cell therapy in September. Piecoro notes that there are still no guarantees on De La Rosa’s health, which will remain somewhat of a mystery until he’s able to face live hitters and throw off a mound during Spring Training.

Many scouts have tabbed De La Rosa as a reliever, as we’ve noted here at MLBTR over the years. De La Rosa typically shows good velocity, averaging between 94 and 95 mph as a starter, but he lacks a quality third offering and has long struggled against left-handed batters (career .286/.363/.489 batting line allowed). A shift to the bullpen will conceivably allow De La Rosa’s velocity to play up even further and can help to limit the number of lefties he faces (while also potentially making him more effective versus lefties by way of increased velocity).

If De La Rosa does make the roster and perform well over the life of a full big league season in his new role, he’d remain controllable for the Diamondbacks for one more winter. De La Rosa was non-tendered by the D-backs a month ago due to the fact that the team didn’t want to risk a projected $3MM salary for him, and he has just four years, 97 days of big league service, so he’ll remain arbitration-eligible next winter.

• Tyson Ross, Padres. San Diego cut Ross and five other players loose on Friday, adding a big name to a thin starting pitching market. Ross missed most of the 2016 season due to injury and had surgery for thoracic outlet syndrome in October, which figured to require a four- to six-month recovery period. He also wouldn’t have been cheap for 2017, making a projected $9.6MM. Nonetheless, Ross would be an interesting free agent even if there weren’t so little good starting pitching available. In 2015, he pitched 196 innings, with a 3.26 ERA, 3.9 BB/9 and an outstanding 9.7 K/9. He also has a career 56% ground ball rate.
• Chris Carter, Brewers. Milwaukee designated their first baseman for assignment last week, then officially non-tendered him yesterday. It isn’t typical to see a home run champ non-tendered, but Carter’s consistently high strikeout totals, consistently low batting average and lack of defensive value made him a tricky case, especially since those factors would have been weighted less heavily by the arbitration process than his gaudy home-run totals. We examined the Brewers’ case for non-tendering Carter back in October.
• Welington Castillo and Rubby De La Rosa, Diamondbacks. That the Snakes would non-tender a consistently productive starting catcher like Castillo rated as one of the tender deadline’s bigger surprises. Castillo batted a fine .264/.322/.423 in 2016 and looks like a strong addition to a rather thin free agent market for backstops. De La Rosa, too, is worth watching this winter — health concerns surely played a role in the Diamondbacks’ decision to cut him loose, and Tommy John surgery could be a possibility at some point after his recent stem cell treatment on his elbow. but De La Rosa’s blistering fastball, solid ground-ball ability and 9.6 K/9 in 2016 make him an intriguing free agent, particularly if teams are optimistic about his health.
• Ben Revere, Nationals. Washington’s decision to non-tender Revere (who we projected would make $6.3MM through the arbitration process this winter) came as no surprise after he hit just .217/.260/.300 while struggling with an oblique injury in 2016. Still, Revere had batted at least .294 in each of the four previous seasons, stealing 142 bases in that span. He’s also just 28. Teams interested in outfield help could, therefore, view him as a candidate to contribute next season.
• Seth Maness, Cardinals. St. Louis’ decision to non-tender Maness was surely due in large part to his health, as he had UCL surgery in August. He was, however, consistently productive as a sort of ground ball specialist in parts of four seasons with the Cardinals, producing a lifetime 3.19 ERA, 5.8 K/9, 1.7 BB/9 and 59.4 GB%. The Cards portray their decision to non-tender him as mostly a roster issue, as the addition of John Gant in the recent Jaime Garcia trade gave them additional bullpen help, and rookie Matt Bowman emerged in 2016 as a ground ball specialist in his own right.
• Jeff Manship, Indians. The 31-year-old righty produced an 0.92 ERA, 7.6 K/9 and 2.3 BB/9 for Cleveland in a terrific 2015 season and helped again in 2016, with a 3.12 ERA. He had long pitched mostly in the minor leagues before that, though, and his 4.6 BB/9 last season didn’t portend a high degree of future success.
• Vance Worley, Orioles. Worley’s teams seemingly continue to view him as a marginal player even as he remains consistently useful. In 2016, pitched 86 2/3 innings for Baltimore, generally pitching out of the bullpen but also making four starts. He produced a 3.53 ERA and a 48.1% ground ball rate, although his peripherals (5.8 K/9, 3.6 BB/9) headed in the wrong direction. He still looks like a credible long reliever, though, and his ability to start also helps.
• Jeff Locke, Pirates. The Bucs’ decision to part ways with Locke was likely an easy one after he produced a miseable 5.44 ERA, 5.2 K/9 and 3.1 BB/9 in 2016, ultimately losing his job in the rotation. Still, Locke has logged at least 127 1/3 innings in each of the last four seasons and could help a team in search of rotation depth this winter.

Castillo had been projected by MLBTR and contributor Matt Swartz to earn a fairly hefty $5.9MM in his final season of control. But in this market, with more teams seemingly in need of catching than there are serviceable backstops to go around, that seemed plenty reasonable.

After all, Castillo is still just 29 years of age and provided the D-Backs with 457 plate appearances of .264/.322/.423 hitting last year, while swatting 14 home runs. That was slightly below a league-average rate of production for a hitter, but is quite useful for a catcher. And Castillo had shown some real upside just a season before, when he popped 17 long balls and OPS’ed .813 over 303 plate appearances following his mid-season acquisition by the Snakes.

Of course, offense isn’t everything, particularly for the catching position. Castillo rated as a slightly below-average framer by StatCorner’s measure in 2016, though he was right at par the season prior. In the view of Baseball Prospectus, though, he was rather terrible at gaining strikes for his pitchers last year.

On the surface, even with the questions about his ability to win the corners for a team’s staff, it might have seemed that Castillo would at least have held trade appeal. Surely, though, that possibility was explored by Arizona before it finalized its course. From the organization’s perspective, it can roll the dice that Chris Herrmann (at a projected $1MM arb salary) will reprise his surprising run from 2016. And it’ll look to help nurture its rotation back to health with a steady hand in a reserve role, as the D-Backs have reportedly agreed to terms with free agent Jeff Mathis, That duo figures to cost a fair sight less than Castillo would have alone.

De La Rosa, whose elbow health is in question, was projected at a $3.0MM tab. That was an amply reasonable amount for his talent, particularly considering that there’s another season of control to go, but the team may not have been encouraged by the medical signals it received.

Last we checked in, the 27-year-old was undergoing stem cell therapy in an effort to avoid Tommy John surgery. He has previously undergone a UCL replacement in his career, and at this point, a repeat procedure surely would’ve caused him to miss all of the 2017 season. In that event, Arizona would’ve been required to promise him the same rate of pay both for 2017 and 2018, all in the hopes that he’d return (and return to form) in the second of those two years.

That being said, it’s tough to give up on a pitcher of De La Rosa’s promise. He had turned in 50 2/3 innings of 4.26 ERA pitching in 2016, and struggled with the long ball, but did post a strong 9.6 K/9 rate to go with his 3.6 BB/9. Some ERA estimators believed he had been a bit unfortunate, as he ended the year with a 3.85 FIP and 3.86 SIERA. De La Rosa brings a mid-nineties heater to the table, and will be an interesting bounceback candidate.

De La Rosa’s rehab has been something of a rollercoaster: he was able to return briefly, then seemed destined to be shut down, and then seemed like he might be headed back to the major league mound by the end of the season. Now, the situation seems a fair bit more dire than had previously been suggested.

Stem cell and other alternatives to surgery have increasingly been utilized by pitchers hoping to reinforce, rather than replace, their ulnar collateral ligaments. The risk of a TJ procedure failing to produce the desired results is heightened significantly in the case of a second trip under the knife, so the stakes are high in De La Rosa’s case.

Given the timing, a TJ procedure in the near-term would clearly keep De La Rosa out for all of 2017. Second-time UCL replacement recipients tend to take longer to make it all the way back, though he’d at least be reasonably likely to make it back for ’18.

De La Rosa is due a raise — though it won’t be a large one — on his $2.35MM arbitration salary. He’s set for free agency before the start of the 2019 campaign, so the next two campaigns are the final ones of team control for Arizona.

All said, then, there’s a lot riding on De La Rosa’s ability to return. Over his 50 2/3 innings this year, he worked to a useful 4.26 ERA and also showed quite a bit of promise with a rising 9.6 K/9. That makes De La Rosa a critical part of the D-Backs’ rotation picture.

Here are some more injury notes from around the game:

• It had seemed that Diamondbacks righty Rubby De La Rosa would be shut down for the year due to ongoing elbow soreness, but that may no longer be the case. As Nick Piecoro of the Arizona Republic tweets, manager Chip Hale says there’s still a chance that De La Rosa could return at the tail end of 2016. He’ll throw side sessions and perhaps even sim games while the team assesses both the health of his elbow and his command, per the skipper. “Maybe the last week of the season we get him in a game to see what he looks like,” said Hale.
• The Dodgers put Brett Anderson on the hill tonight in the Triple-A playoffs and he provided five solid frames, as MLB.com’s Ken Gurnick reports. He is working back from a blister, and showed well with five strikeouts and zero free passes while allowing just one run on three hits. With the victory, Triple-A Oklahoma City stayed alive, meaning that fellow southpaw Scott Kazmir will take his own turn at a rehab outing, per Bill Plunkett of the Orange County Register (via Twitter). Kazmir has been battling thoracic spinal inflammation, and his timeline has remained murky. It’ll be interesting to see whether either or both starters play a role down the stretch or in the postseason for the Dodgers. Kazmir is likely not to opt out of his contract regardless, but Anderson will be looking to show that he’s at full health entering another run at free agency. Still just 28 years of age, back issues have limited Anderson to just a pair of major league outings thus far — neither of which went well at all.
• Cardinals closer Seung-hwan Oh is back in action after resting a groin injury, MLB.com’s Jenifer Langosch tweets. Oh has been a tremendous find for St. Louis, providing 72 1/3 innings of 1.87 ERA ball on the year, and his return will be critical with just two weeks to go. His 2017 option is already guaranteed — he has accumulated exactly the thirty games finished that he needed — but the team was already surely excited to pick it up at just $2.75MM.
• The Pirates are still awaiting the return of outfielder Starling Marte, who has dealt with back spasms. Skipper Clint Hurdle says that he believes Marte will be ready to go tomorrow, as Rob Biertempfel of the Pittsburgh Tribune-Review tweets. Unfortunately, it’s likely too late for the talented outfielder to impact the team’s postseason chances; Pittsburgh sat 5.5 games out of Wild Card position entering play today. The multi-talented 27-year-old has turned in another high-quality campaign, with a .311/.362/.457 batting line, nine home runs, and 47 steals, and his extension continues to look like an outstanding investment.

Here’s more on some injury situations around the game:

• Diamondbacks righty Rubby De La Rosa has suffered a setback in his efforts to come back from a forearm injury, Steve Gilbert of MLB.com tweets. He’s headed for an MRI to see where things stand. It seems as if there’s little reason to expect the 27-year-old to return to the majors this season. That’s a tough blow for the D-Backs, who surely would like to get a longer look at a pitcher who showed a fair bit of promise this year. Over 47 2/3 innings earlier in the season, De La Rosa worked to a 4.15 ERA with 9.3 K/9 against 2.8 BB/9.
• The Astros will be without Colby Rasmus for a month or more after he underwent surgery to remove a cyst from his ear, Jake Kaplan of the Houston Chronicle tweets. Rasmus has been struggling for some time, and it’s fair to wonder whether the issue may have played a significant role. He’ll need to return in good form to provide a boost to the ’Stros — and to bolster his fading free agent position.
• Marlins first baseman Justin Bour isn’t progressing in his attempt to return from an ankle injury, as Barry Jackson of the Miami Herald reports on Twitter. In fact, manager Don Mattingly says that Bour “went backwards” of late, with the team’s expectation now being that he won’t return until at least early September. That certainly seems to open some room for Miami to look into adding a bat to chip in down the stretch.
• Athletics righty Sonny Gray only just began forearm exercises today, John Hickey of the Bay Area News Group reports. He won’t begin throwing again unless and until the inflammation subsides. At this point, it seems far from certain whether he’ll make it back to a major league hill this season.
• The Mariners may soon send reliever Steve Cishek out on a rehab assignment, Bob Dutton of the Tacoma News Tribune reports. It appears that his hip labrum issue is indeed as minor as the team had suggested. Meanwhile, fellow pen righty Tony Zych is also finally making some progress and will begin a rehab assignment on Friday. Adding those two arms down the stretch would provide a significant boost to Seattle’s late-inning mix.

Miller, 25, was acquired from the Braves over the winter with hopes that he’d join Zack Greinke to form an imposing 1-2 punch atop the Snakes’ staff. Instead, he has fallen apart since arriving in Arizona. In 45 2/3 innings over ten starts, Miller has surrendered 7.09 earned runs per nine while recording an untenable 30:29 K/BB ratio. He’s been torched with the long ball while exhibiting a 1.5 mph drop in velocity as against the average fastball he threw over a successful 2015 season.

It appears that Miller’s DL stint will arise as a result of a finger issues he’s been battling of late after scraping his hand on the mound after releasing pitches. But it’s hard to ignore the role that his ugly start has played in the decision, and that could impact his progress back toward the majors.

Arizona desperately needs to get Miller on track. The club entered the day seven games under .500 after a winter in which it dropped over $200MM on Greinke and gave up three significant assets — center fielder Ender Inciarte, pitching prospect Aaron Blair, and top overall 2015 draft pick Dansby Swanson — for the rights to Miller.

The still-youthful righty is owed $4.35MM this year and has two more seasons of arb control remaining. But the Diamondbacks will need him to pitch like the front-of-the-line arm they thought they were getting for that trade to look like anything but a bust. Of course, that may have been asking too much of Miller even at the time the deal was struck.

A timetable on Miller is wholly unclear at present. Conceivably, he could rest up and miss the minimum fifteen-day stretch. It could be, though, that the organization will spend some time looking for a fix, possibly sending Miller out on a rehab assignment to get some work in before he returns.

With Miller officially out of the rotation for the time being, the D-Backs will be even more stretched. The club surely hoped its rotation would be a strength, but Greinke and Patrick Corbin have also fallen shy of expectations — albeit nowhere near to the same extent as Miller — while De La Rosa and Robby Ray have been solid but largely unspectacular.

De La Rosa tells Jack Magruder of Fanragsports.com (via Twitter) that he expects to miss a month. There does not appear to be any concern that he’ll need surgery, which is certainly good news. But the injury looks to be significant, and it’s always troubling to see a young pitcher dealing with elbow troubles.

The organization announced several other roster moves, too. Among them, Josh Collmenter was activated from his DL stint. Also coming up is young slugger Peter O’Brien, as are righties Dominic Leone and Silvino Bracho. The club will need to promote new rotation options early next week, with former top prospect Archie Bradley set to get another shot at the majors.

Bradley has scuffled in two outings earlier this year, but has been better at the Triple-A level. O’Brien, who has shifted from catcher to outfielder, made a brief major league debut last year. He’s put up a stellar .306/.330/.601 batting line in 182 plate appearances at Triple-A.
