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.

Let’s start with the Korea Baseball Organization, the top league in South Korea. Remember, teams in the KBO and other leagues face limits on the number of non-native players they can employ. That creates a lot of pressure to secure big production from those roster spots, and often spurs mid-season change. (Statistics courtesy of the always excellent MyKBO.)

The top performers …

• Former Phillies slugger Darin Ruf marauded the KBO once again, though he wasn’t quite as awesome this year (.911 OPS, 22 home runs) as he was in 2018 (1.024 OPS, 33 home runs). After scoring with Ruf, the Samsung Lions went after Mac Williamson in a mid-season move. But Williamson failed to gain traction in his forty contests, hitting a tepid .273/.329/.409.
• Several other hitters joined Ruf as repeat KBO participants and star-level performers. Outfielder Jamie Romak has also now completed three excellent campaigns with the SK Wyverns. Like Ruf, he took a step back this year (1.001 OPS to .878 OPS), likely reflecting a KBO baseball de-juicing effort.
• After a brief but promising showing in 2018, Jerry Sands rewarded the Kiwoom Heroes for bringing him back by swatting 28 dingers and batting a robust .305/.400/.543 on the year. Jared Hoying wasn’t quite as productive, but turned in a solid sophomore campaign with the Hanwha Eagles (.284/.343/.460).
• The KT Wiz continued to benefit from their 2017 find of outfielder Mel Rojas Jr., who never got a big-league call-up from the Pirates or Braves. He slashed a robust .322/.384/.530 with 24 homers in his third KBO season.

Several KBO newcomers found something in their new organizations …

• Jose Miguel Fernandez took a difficult path to the majors and did not receive a lengthy opportunity at the game’s highest level, but displayed his intriguing blend of hitting ability with the Doosan Bears. Appearing in all 144 contests, Fernandez poked 15 long balls and slashed a hefty .344/.413/.483.
• The KIA Tigers dropped former Cardinals flash-in-the-pan outfielder Jeremy Hazelbaker after just eleven contests. That may have been a quick leash, but they ended up making out well with Preston Tucker. The former MLB reserve outfielder ultimately slashed .311/.382/.479 with nine home runs.

Other KBO organizations are likely to go back to the drawing board after cycling through multiple players …

• Another team changing horses in mid-stream was the LG Twins, who tired of former Phillies first bagger Tommy Joseph after he slashed .274/.335/.426 with nine long balls in 54 games. The club turned to another OBP-challenged slugger in the left-handed-hitting Carlos Peguero, who provided a bit more overall offense (.286/.333/.472) but no additional dingers (9) in his 57 appearances.
• Former Padres infielder Carlos Asuaje struggled in 49 games with the Lotte Giants, slashing just .252/.358/.368. He was replaced by Jacob Wilson, a former Cards and Nats farmhand, but Wilson wasn’t much more effective (.251/.352/.433 with nine home runs). (Wilson and Rojas were the only two hitters to appear in the KBO this year without prior MLB experience.)
• The NC Dinos opened the year with Christian Bethancourt behind the plate, but he didn’t do enough damage to hang onto his roster spot, with a .246/.311/.404 line in 53 games. That led to a mid-season change to former big league outfielder Jake Smolinski. Unfortunately, he managed only a .229/.301/.439 slash of his own.

• Veteran lefty Tom Gorzelanny has declined his outright assignment with the Indians and is now a free agent, the team has announced. The Indians designated Gorzelanny for assignment on Monday after he allowed seven runs in three innings for them. Gorzelanny, who turns 34 this week, has a career 4.40 ERA, 7.3 K/9 and 3.9 BB/9 in parts of 12 seasons with the Pirates, Cubs, Nationals, Brewers and Tigers in addition to the Indians.
• The Cardinals have announced that they’ve allowed outfielder Carlos Peguero to depart for the Tohoku Rakuten Golden Eagles in Japan. They will receive cash considerations in return. The 29-year-old Peguero has played with the Mariners, Royals, Rangers and Red Sox in parts of five big-league seasons, but has never stuck, accumulating just 319 career plate appearances. He’s shown big power in the minors, though, with 95 home runs and a .277/.346/.520 in the equivalent of about three full seasons at Triple-A.
• The Rays have signed reliever Casey Coleman to a minor league deal, Marc Topkin of the Tampa Bay Times tweets. Coleman opted out of his deal with the Mariners last week after posting a 2.08 ERA, 8.8 K/9 and 2.8 BB/9 in 39 strong innings with Triple-A Tacoma.
• One of Coleman’s new Durham Bulls teammates is lefty Dana Eveland, who was designated for assignment this week. Via SB Nation’s Chris Cotillo (on Twitter), Eveland has accepted the Rays’ outright assignment. He posted an 8.55 ERA, 8.1 K/9 and 6.8 BB/9 in 20 innings of relief with the Rays this season.
• The Pirates have outrighted catcher Jacob Stallings, as the Pittsburgh Post-Gazette’s Bill Brink tweets. The Bucs designated the defensive specialist for assignment last week. The 26-year-old has batted just .200/.235/.326 this season, but he received a brief callup because of a rash of injuries to Pirates catchers.

Peguero, 29 next month, split the 2015 season between the Rangers and Red Sox organizations, seeing action in 30 games with Texas. Peguero batted just .186 in his 84 plate appearances with the Rangers, but he also posted a .310 on-base percentage and slugged .414 thanks to the fact that eight of his 13 hits went for extra bases (four doubles, four homers). Peguero is a legitimate power threat, as evidenced by his career .276/.345/.528 batting line at Triple-A. He belted 30 homers in the minors as recently as 2014 and hit a combined 25 between the Majors and Triple-A last season. Making consistent contact, however, is an issue for Peguero, who has punched out in 39.5 percent of his Major League plate appearances and has a 31.7 percent strikeout rate in parts of five Triple-A seasons.

Peguero, 28, was designated for assignment on June 4th in order to make room for the newly-added Alejandro De Aza.  Peguero himself was a new addition for the Red Sox as Boston acquired him in late May from the Rangers.  The Red Sox likely brought in Peguero to give them an additional left-handed bat in the outfield, but De Aza filled that need when he came aboard.

In total, Peguero saw only six big league plate appearances with Boston.  He’s always had plenty of pop — as his 30 Triple-A home runs last year attest — but Peguero strikes out quite a bit while walking only at the league average.  Now it remains to be seen whether Peguero will bring his big bat to the minors or to NPB.

As the MLBTR DFA Tracker shows, there are now eight players in DFA limbo: Rickie Weeks, J.C. Ramirez, Darwin Barney, Trevor Cahill, Erik Kratz, Bobby Wilson, Tim Stauffer, and Matt Dominguez.

Boston added Peguero just over a week ago, and he saw only six plate appearances with his new club. He’s always had plenty of pop — as his 30 Triple-A home runs last year attest — but Peguero strikes out quite a bit while walking only at the league average. Still, his left-handed power bat holds reasonable appeal, though it remains to be seen whether another team will be inclined to give the out-of-options slugger an active roster spot

Boston certainly does not appear in want of options in the outfield, but its current mix includes only one left-handed bat: Daniel Nava (a switch-hitter). It is conceivable — though far from certain — that the addition of Peguero could ultimately lead to a transaction involving Nava, though the team has alternative means of clearing active roster space in the near term.

Peguero, 28, brings poor on-base ability but strong power numbers to the table, as his .186/.310/.414 line this year suggests. He did hit 38 home runs at the Triple-A level last year, though he struck out over a third of the time on the way to that prodigious long ball output.

More from the AL West…

• After speaking with Mariners director of minor league player development Chris Gwynn, Divish also reports that top prospect and 2014 first-rounder Alex Jackson has been shut down with a shoulder issue. According to Gwynn, Jackson hurt his left shoulder in Spring Training while diving for a ball, and the injury has likely hampered his swing this season. That would explain how Jackson, who slashed .280/.344/.476 in his pro debut with the club’s Rookie-level affiliate in 2014, saw his production plummet to .157/.240/.213 with Class-A Clinton in 2015. Jackson will head to extended Spring Training for the time being as he works to rehab the injury.
• Athletics righty Jarrod Parker underwent successful surgery to repair the fractured medial epicondyle in his right elbow, reports MLB.com’s Jane Lee. The club briefly thought that Parker might need a third Tommy John surgery after he initially sustained the injury, making this operation something of a relief, despite the its generally unfortunate nature. There’s still no timetable on his recovery, however.
• The Rangers’ decision to designate Carlos Peguero earlier today opened a spot on the 25-man roster and was likely influenced by the impending return of Josh Hamilton (who will pick up most of Peguero’s at-bats in the corner outfield), but Jeff Wilson of the Fort Worth Star-Telegram tweets another wrinkle to the move. The open spot on the 40-man roster won’t be filled immediately — Klein was already on the 40-man, as is Hamilton — which could allow the Rangers to give former first-round pick and consensus Top 100 prospect Alex “Chi Chi” Gonzalez a look in the rotation if they wish. Gonzalez hasn’t dazzled in his first taste of Triple-A pitching, but the 23-year-old does have a lifetime 3.14 ERA with 7.0 K/9 and 3.0 BB/9 in the minors.
• Albert Pujols left the game tonight after being hit by a pitch on the hand, but Angels GM Jerry Dipoto told reporters, including Mike DiGiovanna of the L.A. Times (Twitter link) that there are no fractures. Pujols will be day-to-day with a bruise but shouldn’t miss any significant amount of time.

The club needed a roster spot for righty Phil Klein, who will start tonight. But in the bigger picture, Peguero’s role — left-handed power bat at the outfield corner — will be taken over soon by Josh Hamilton.

Peguero, 28, has hit at about a league average clip  — with marginal on-base numbers (.314 OBP) offset by good power output (.414 slugging percntage with four home runs) — through his 84 plate appearances on the year. That continues a rather familiar narrative for the slugger, who launched 38 long balls at Triple-A last year while striking out 189 times in 556 plate appearances.

• Reds pitcher Raisel Iglesias will make his major league debut tomorrow, writes Jason Haddix for MLB.com. He’ll be opposed by Cardinals hurler Carlos Martinez. The Reds committed to a seven-year, $27MM contract with Iglesias during the 2014 season.
• The Orioles selected the contract of knuckleballer Eddie Gamboa, writes Brittany Ghiroli of MLB.com. Wesley Wright was added to the disabled list in a corresponding move. Gamboa, 30, had yet to reach the majors although he figures to bounce back and forth this year. He’ll serve as depth in case Kevin Gausman is needed in long relief in the next couple games.
• Pirates utility man Pedro Florimon has cleared waivers, tweets Bill Brink of the Pittsburgh Post-Gazette. He has been outrighted to Triple-A. Per Brink (also Twitter), since Florimon has been outrighted before, he can decline and become a free agent. Brink is told no decision has been made.
• The Rangers have announced that they’ve selected the contract of corner outfielder Carlos Peguero and recalled pitcher Jon Edwards. They’ve also moved Derek Holland (shoulder) to the 60-day disabled list and Ryan Rua (ankle) to the 15-day disabled list. Peguero is in the Rangers’ lineup tonight. The 28-year-old Peguero has played briefly, and not particularly impressively, for the Mariners and Royals in parts of four big-league seasons, but he’s demonstrated serious power in the minors (with 30 homers for Triple-A Omaha last year) and in Spring Training.
• The Giants have outrighted infielder Ehire Adrianza to Triple-A Sacramento, MLB.com’s Chris Haft tweets. The team designated Adrianza for assignment last week. Adrianza, 25, hit .237/.279/.299 in 106 plate appearances while playing mostly shortstop and second base for the Giants last season.
• The Yankees have announced that they’ve promoted lefty Matt Tracy. To clear space for Tracy on the 25- and 40-man rosters, the Yankees optioned lefty Chasen Shreve to Triple-A Scranton/Wilkes-Barre and moved Ivan Nova to the 60-day disabled list. Tracy will need to be added to the Yankees’ 40-man roster. Tracy’s stay on the roster could turn out to be short, however — the Yankees can use some quick bullpen reinforcements after their 19-inning game against the Red Sox last night, and Tracy would presumably join the team for that purpose. The 26-year-old posted a 3.76 ERA with 5.3 K/9 and 3.3 BB/9 in 150 2/3 innings between Double-A and Triple-A last year.
• Two players remain in DFA limbo, via MLBTR’s DFA Tracker: lefty Sam Freeman (Rangers) and outfielder Carlos Quentin (Braves).

• First baseman/outfielder Marc Krauss, who was designated for assignment by the Angels last week, has cleared waivers and been outrighted to Triple-A, tweets Mike DiGiovanna of the Los Angeles Times. Krauss hit .194/.279/.323 with six homers in 208 PAs for the Astros last season but was designated to clear room on the 40-man roster when the Halos acquired Kyle Kubitza from the Braves.
• The Rangers have signed both Carlos Peguero to a minor league deal with an invite to Spring Training, executive VP of communications John Blake announced (Twitter link). Peguero, 28 next month, had an excellent season with the Royals’ Triple-A affiliate in 2014, hitting .266/.349/.563 with 30 homers. The former Mariners prospect has shown huge power throughout his minor league career but hasn’t been able to carry his success over to the Majors, where he’s hit .196/.245/.379 and fanned in nearly 39 percent of his 229 PAs.
• The Rangers also re-signed Guilder Rodriguez to a minor league deal, tweets Evan Grant of the Dallas Morning News. The 31-year-old infielder was a nice story in an otherwise dreadful Rangers season in 2014, as he reached the Majors for the first time after 13 minor league seasons and collected a pair of hits in 12 at-bats. Rodriguez hit .260/.340/.290 in 284 PAs at Triple-A.
• Catcher Steven Lerud has signed a minor league deal with the Nationals that contains an invite to big league camp, tweets Mark Zuckerman of CSN Washington. The former Pirates third-rounder (2003) saw a bit of Major League time with the Phillies in 2012-13, but the 30-year-old has never received a prolonged look in the bigs. He’s a lifetime .225/.361/.337 hitter at Triple-A and has caught an excellent 34 percent of attempted thieves on the basepaths over the life of his career.

Peguero saw little action last year with Kansas City, instead working for the club’s Triple-A affiliate. At that level, he posted a .912 OPS with 30 home runs in 418 plate appearances. Peguero has generally done quite well against the best arms in the minors, but has yet to receive a prolonged chance at the MLB level. He struggled to reach base in a 155-plate appearance stint back in 2011 with the Mariners, and has not gone to bat over 57 times in a big league season since.

Here’s the latest out of Kansas City:

• In a piece discussing the anticipated loss of Butler, Andy McCullough of the Kansas City Star indicates that the team remains intent on making impact additions to its roster, particularly to the rotation. The club has had at least opening discussions with agents for Ervin Santana, Brandon McCarthy, Brett Anderson, Jason Hammel, and Jon Lester, writes McCullough.
• Francisco Liriano is also a consideration for the Royals, as are many other arms in the mid-tier of free agents, Jon Heyman of CBSSports.com reports. And trade possibilities are also being explored. The team is still dabbling in the markets for Lester and Shields, Heyman notes, but seemingly has eyes for Liriano and Santana
• Torii Hunter is a definite target, says Heyman. The team believes that he is still a reliable bat and sees him as a quality fit.
• Kansas City is considering utilizing Carlos Peguero in a time-share in right field and at DH, tweets Jeffrey Flanagan of FOX Sports Kansas City. That plan would be particularly interesting if the team could pair the left-handed-hitting Peguero with a veteran right-handed bat of Hunter’s ilk.

• Infielder Adam Rosales has accepted an outright assignment with the Rangers, tweets Anthony Andro of FOX Sports Southwest. The well-travelled Rosales has 920 MLB plate appearances over his career, and owns a .219/.287/.335 line in that stretch.
• Outfielder Xavier Avery of the Mariners has cleared waivers and been outrighted to Triple-A, reports Greg Johns of MLB.com (via Twitter). The 24-year-old figures to be a useful depth piece for Seattle.
• Andy McCullough of the Kansas City Star reports (via Twitter) that the Royals have outrighted outfielder Carlos Peguero to Triple-A Omaha after he cleared waivers. According to a previous report from McCullough, the Royals made a clever move — Peguero and his agent might use a different adjective — by claiming left-hander Patrick Schuster from the Padres and designating Peguero for assignment. Per McCullough, Schuster never really had a shot to crack the roster, and the Rule 5 pick was returned to his original organization, the Diamondbacks. However, the move gave Kansas City cause to DFA Peguero, and the 10-day DFA window helped ensure that he could be slipped through waivers more easily, as he didn't have to be waived until eight days after his DFA (most teams' 40-man rosters were set by the time Peguero was placed on waivers). 

The 27-year-old former Mariner has had a sparkling spring, posting a .313/.436/.563 triple-slash in 39 plate appearances. But he always faced an uphill battle in unseating Justin Maxwell for the fourth outfielder role. He could find a new home via trade, though any team acquiring him that way (rather than by signing him if he is waived) would need to consider him a strong candidate for an Opening Day spot, as Peguero is out of options.
