This marks the second suspension of note for Santiago this season alone. He was served a 10-game suspension for possessing a foreign substance. Santiago was adamant in his defense in that case, though the suspension was ultimately at the discretion of the umpires who made the call on the field.

The well-traveled veteran had been a solid contributor for the Mariners this season through 13 appearances. As a multi-inning option out of the pen, the 33-year-old pitched to a 3.42 ERA/3.12 FIP across 26 1/3 innings with a 25.6 percent strikeout rate, 9.4 percent walk rate, and 44.7 percent groundball rate. The strikeout rate was quite a bit higher than his 20.7 percent career average, though the improvement tracks back through the 2019 season as well. He did not pitch in 2020.

For his career, Santiago owns a 4.12 ERA/4.86 FIP across 947 innings for the White Sox, Angels, Twins, Mets, and Mariners. He was mostly a starter earlier in his career, making at least 23 starts in each season from 2013 to 2016. His success in that role was marginal, however, as he never again topped the 1.2 fWAR he put up for the White Sox in 2013.

2:20pm: Major League Baseball announced Tuesday that Mariners lefty Hector Santiago has been suspended 10 games and been fined an undisclosed amount for possessing a foreign substance on his glove in the fifth inning of Sunday’s game against the White Sox. Santiago is appealing the decision.

Mariners manager Scott Servais said after the game that umpire Phil Cuzzi was mistaken and that there was no illegal substance on Santiago’s glove — only rosin (which is permissible under MLB rules) and sweat. The league, after conducting an analysis of Santiago’s glove, clearly does not agree and has elected to punish the veteran lefty. Santiago’s suspension will be held in abeyance until the appeal process is complete. As ESPN’s Jeff Passan tweets, Santiago’s case will now be heard by an arbiter  who works for Major League Baseball, which all but eliminates the possibility of the suspension being overturned. It could potentially be reduced, Passan suggests.

The 33-year-old Santiago has been quite effective with the Mariners thus far in 2021 after not pitching in the big leagues last season. He’s worked to a 2.65 ERA with a 23-to-7 K/BB ratio in 17 innings of work. This year’s 32.4 percent strikeout rate is easily a career-high, which will raise some eyebrows in light of the suspension, but it should be noted that Santiago hasn’t seen any appreciable uptick in spin rate this year. The spin on his four-seam fastball, in fact, has dropped from its previous levels, while the spin on his slider is right in line with his career marks.

Under the league’s new enforcement policy for foreign substances, the Mariners won’t be able to replace Santiago on the roster if his suspension is indeed upheld. They’ll have to play a man down while he serves his punishment.

Seattle manager Scott Servais confirmed (via Jesse Rogers of ESPN) that Santiago was deemed to have used a foreign substance but claimed Cuzzi’s judgment was incorrect. “He had rosin all over himself. Phil thought he had sticky stuff on his glove,” Servais said. “There is no sticky stuff in the glove.” Rosin is permitted under the league’s substance policy.

If Santiago’s ejection is ultimately deemed to be due to a foreign substance and not rosin, as Servais suggested, the left-hander wiill be subject to a ten-day suspension under the terms of Major League Baseball’s new enforcement of the prohibition against ball doctoring. Santiago would become the first player to be disciplined since MLB’s crackdown went into effect on Monday. The Mariners would not be permitted to replace him on the active or 40-man rosters during the course of any suspension.

The 33-year-old Santiago first appeared in the majors in 2011 and has thrown just under 1000 innings at the big league level. Signed to a minor league deal last month, he’s made nine appearances since being selected to the roster. Santiago entered play today with a 2.45 ERA/2.89 SIERA across 14 2/3 innings.

Santiago, whom the Mariners signed to a minor league contract earlier this season, will now have an opportunity to appear in the majors for a 10th year. The 33-year-old is best known for a productive run with the White Sox and Angels from 2011-15, but his numbers have fallen off since then among a few teams. He most recently pitched in the majors in 2019 between the White Sox and Mets, with whom he combined for a 6.68 ERA/4.89 SIERA in 33 2/3 innings (most of which came in relief). Santiago has thrown 14 frames with the Mariners’ Triple-A affiliate this year and yielded seven earned runs on 10 hits (including five home runs) with an eyebrow-raising 22 strikeouts against five walks.

Delaplane, 26, has been with the Mariners since they chose him in the 23rd round of the 2017 draft. He has since posted impressive minor league production, including a stunning 0.49 ERA with a similarly excellent 43.3 percent strikeout rate against a 6.7 percent walk rate during a 37-inning Double-A debut in 2019. However, with Delaplane having undergone Tommy John surgery in April, Seattle doesn’t believe he’s worth a 40-man roster spot at this point.

Kelly, 32, announced his retirement from professional baseball in August 2019. He sat out the 2020 season but is making a comeback attempt after more than a year and a half away. Kelly’s MLB time to this point has been bookended by stints with the Mets in 2016 and 2018, although his most extensive playing time came with the 2017 Phillies. Altogether, he’s taken 188 plate appearances at the highest level, slashing .203/.288/.323. Kelly carries a much better .268/.368/.382 mark in parts of eight seasons at Triple-A and has experience all around the diamond.

The Mariners also signed southpaw Williams Jerez to a minors deal, per his transactions log at MLB.com. He’s also been assigned to Triple-A. Jerez tossed 25 1/3 innings across 29 major league relief appearances for the Angels, Giants and Pirates from 2018-19. He didn’t find much success at the MLB level, working to a 5.33 ERA/5.02 SIERA. Jerez has been better in Triple-A, where he’s tossed 123 2/3 frames of 4.15 ERA ball with solid strikeout and walk rates (27.1% and 8.9%, respectively).

Kelly and Jerez are joined on the Rainiers active roster by longtime big leaguer Héctor Santiago. The veteran lefty signed with Seattle earlier this month and has already made a pair of starts for Tacoma, working nine innings of four-run ball with a whopping 16 strikeouts and five walks. Santiago was a mainstay in big league rotations for much of the last decade, throwing 100-plus innings in five different seasons. He didn’t pitch last year after being released by the Tigers in July. Santiago offers an experienced depth option for a Seattle club relying on quite a few young arms at the major league level right now.

Santiago, 32, joined the Tigers on a minor league deal last offseason after mostly working as a reliever in 2019 and combining for 33 2/3 innings of 6.68 ERA/5.89 FIP ball with the White Sox and Mets. That continued a multiyear run of subpar production in the majors for Santiago, who served primarily as a starter earlier in his career and generated solid results for for the White Sox and Angels. During his peak from 2011-15, Santiago notched a 3.55 ERA/4.54 FIP with 8.25 K/9 and 4.00 BB/9 over 532 2/3 innings.

The Tigers didn’t say why they placed Skubal on the injured list when they made the move July 10. Regardless, it’s encouraging to see one of baseball’s top pitching prospects on his way back. The 23-year-old Skubal, who ranks as MLB.com’s 46th-best farmhand, was dominant in his first taste of Double-A action in 2019 with a 2.13 ERA/1.26 FIP and 17.43 K/9 against 3.63 BB/9 across 42 1/3 frames.

TODAY: Jordan Zimmermann is dealing with the same sort of forearm soreness that sapped him of much of the 2019 season, per Chris McCosky of The Detroit News. If he can stay healthy – a big if – Zimmermann would look to make the most of a short season by proving his arm still plays at the major league level. This will be the final year of the five-year, $110MM pact he signed with the Tigers before the 2016 season.

It’s been a tough couple of years for Zimmermann, who will end his contract without ever making 30 starts in a season after doing so in each of his final four seasons with the Nationals. Despite the precipitous drop in performance, the Tigers were nonetheless turning to Zimmermann as a veteran stopgap in a rotation that will soon be overrun by high-upside prospects like Tarik Skubal, Matt Manning, Franklin Perez, Casey Mize, and Joey Wentz. The rotation is already without Daniel Norris, who has yet to pitch in camp after testing positive for coronavirus.

In the meantime, the Tigers are scrambling to fill out the rotation behind ace Matthew Boyd. Veteran Ivan Nova was brought in to soak up innings (34 starts, 187 innings in 2019), and Spencer Turnbull figures to slot in somewhere in the middle of the rotation after a mostly-strong showing in 2019. Turnbull went 3-17 last season with a 4.61 ERA/3.99 FIP. He’s done a nice job of limiting long balls throughout his two seasons in the majors, and if he can improve upon some control issues that led to an AL-high 16 hit batters and 3.6 BB/9, the Tigers hope Turnbull can level off his 4.76 career ERA and land closer to his 3.88 career FIP mark.

Beyond those three, the Tigers are working on extending the innings of Dario Agrazal, Shao-Ching Chiang, Hector Santiago, and Tyler Alexander to potentially fill out the rotation. Former Rookie of the Year Michael Fulmer also has a chance to get some rotation innings, writes McCosky. Fulmer missed all of 2019 after undergoing Tommy John surgery.

Of the youngsters in camp, Mize probably has the best shot of cracking the rotation. Under normal circumstances, Mize would be ticketed for Triple-A after 22 starts with a 2.55 ERA in Double-A last year, but without minor league games to further his development, count Mize among the many young stars with a slightly better chance of breaking into the big leagues sometime during the shortened 2020 season. Seven days on the taxi squad will be enough for the Tigers to secure an extra year of service time, notes McCosky, but manager Ron Gardenhire doesn’t plan on making any official decisions until knowing more about the health of Zimmermann and Norris.

Santiago had some rather productive campaigns earlier in his career. But at 32 years of age, he has settled into the existence of a journeying southpaw swingman.

Over the past three years, Santiago has transitioned from membership in a 5-man rotation to long relief duties. He carries only a 5.20 ERA in the 206 innings he has thrown during that span. Santiago has struck out 8.5 batters per nine over that time but has also handed out excessive numbers of walks (4.9 per nine) and home runs (1.7).

It’s tough to imagine Santiago having much of a shot at the Detroit rotation in camp. But he could challenge for a bullpen role or otherwise slot into the Triple-A staff to provide depth.

In other news, backstop Welington Castillo was reinstated from the family medical emergency leave list. He’ll technically serve as the 26th man in today’s doubleheader, meaning that the team will have to make a further active roster move thereafter.

Santiago, 31, is in his third stint with the Chicago organization. He opened his career on the South Side and also pitched there last year. Santiago struggled in a brief MLB stint earlier this year with the Mets. In eighty total frames at Triple-A in 2019, he carries a 4.50 ERA with 71 strikeouts and 32 walks.

This will be the third White Sox tour for Santiago, whom the team selected in the 30th round of the 2006 draft. Santiago wound up pitching with the White Sox from 2011-13, during which he notched a 3.41 ERA/4.49 FIP in 224 2/3 innings.

Chicago dealt Santiago to the Angels in a noteworthy three-team trade heading into the 2014 campaign. After stints with the Halos and Twins, Santiago returned to the Sox on a minors deal in February 2018. He went on to throw 102 innings (49 appearances, seven starts) of 4.41 ERA/5.09 FIP ball with 9.09 K/9 and 5.29 BB/9 at the big league level last season.

Now, Santiago will once again try to turn a minors pact with the White Sox into a major league opportunity. He’ll have to perform better than he did as a Met, though. While Santiago did log a 3.35 ERA over 43 innings with the Mets’ Triple-A affiliate this year, his run prevention success came with far less encouraging peripherals. The 31-year-old then fell flat over eight innings with New York, where he gave up six earned runs on 10 hits and five walks (with six strikeouts).

A former starter for the White Sox, Angels and Twins, the 31-year-old Santiago joined the Mets on a minor league deal over the winter. Santiago didn’t crack the Mets’ roster at first, instead opening the year at the Triple-A level. He logged a 3.35 ERA/4.94 FIP with 7.95 K/9 and 4.81 BB/9 in 43 innings as a member of New York’s top affiliate before the club summoned him to the majors in late May.

While Santiago has worked as a starter in the minors this season, he functioned exclusively as a reliever with the Mets before they cut him from their 40-man. In eight innings, Santiago allowed six earned runs on 10 hits and five walks (against six strikeouts). Santiago could end up heading back to Syracuse next, though he’ll be able to reject an outright assignment to the minors if he wants.

There’s no timetable for how long Lugo is expected to miss. The right-hander himself told reporters that the plan is to rest for a few days, adding that he’s hopeful this can be a relatively short absence (Twitter link, with video, via Anthony DiComo of MLB.com). The discomfort in his shoulder began in his most recent outing and is only something he feels when pitching, per Lugo.

It’ll be another hit to the Mets’ pitching staff, as Lugo has arguably been their best setup reliever, pitching to a 3.12 ERA with 11.8 K/9, 2.1 BB/9, 1.04 HR/9 and a 43.9 percent ground-ball rate in 26 innings so far in 2019. Only fellow righty Robert Gsellman, the team’s other top setup option, has logged more innings (27 1/3) out of the bullpen so far.

Meanwhile, free-agent signee Jeurys Familia, brought back to solidify the team’s late-inning mix, has struggled and already spent a bit of time on the IL himself. With Lugo sidelined for at least 10 days, Familia will have to take on a larger role. To his credit, however, Familia has tossed a pair of shutout innings since returning from that short stay on the injured list.

As for Santiago, he’ll join the club after logging a 3.35 ERA in 43 innings of Triple-A ball (seven starts, one relief outing). Solid as that number appears, Santiago is toting an unsightly 38-to-23 K/BB ratio in that time and has benefited from a .235 average on balls in play while pitching for Syracuse. Santiago struggled with similar control issues for the White Sox last year when he averaged 5.3 BB/9 over 102 innings, en route to a 4.41 ERA.

Although Santiago has been starting in the minors, he won’t get the ball for tonight’s game. That nod will go to Wilmer Font, the team announced an hour ago. The Mets had originally indicated that Drew Gagnon would start tonight, but they announced earlier this morning that Gagnon wouldn’t take the ball to open the game after all.

Mesoraco, Hechavarria, and Davis each had upward mobility clauses in their contracts that went into effect last Wednesday, though there hasn’t been any word on whether any other teams had interest in any of the trio.  This doesn’t appear to have been the case for Mesoraco, as Mike Puma of the New York Post reports (Twitter link) that Mesoraco has informed the Mets that he won’t go to Triple-A, and wants to be released.  Mesoraco is even prepared to retire if he isn’t granted his release, according to MLB.com’s Anthony DiComo (via Twitter).

Mesoraco’s situation is perhaps the most surprising, as indications were that he would serve as the backup catcher, since Travis d’Arnaud is likely to begin the season on the injured list.  This could mean that a change in d’Arnaud’s status, or that the Mets would simply instead prefer to use another internal candidate in Tomas Nido as Wilson Ramos’ backup.

The Mets’ outfield situation was already pretty crowded, so Gomez and Davis faced something of an uphill battle in winning jobs.  Brandon Nimmo and Michael Conforto have everyday jobs spoken for, while Jeff McNeil will get at least a share of the left field playing time, with Keon Broxton and Juan Lagares serving as backup outfielders.

O’Rourke pitched quite well in camp while Santiago struggled, though in the end, the Mets chose to take neither left-hander on their Opening Day roster.  This will leave Justin Wilson and Luis Avilan (another minor league signing who is likely to make the team) as the southpaw options out of New York’s bullpen.

The Hechavarria news bodes well for Luis Guillorme’s chances of winning the utility infield job.  McNeil will also see some time in the infield mix when he isn’t playing left field, and J.D. Davis looks to be the team’s top option at third base for the time being.  Of course, the Mets’ infield situation will be in flux once Todd Frazier and Jed Lowrie are healthy.

Elsewhere in the division…

• Because of the numerous off-days baked into the early-season schedule, the Mets are likelier to open the season with seven relievers than they are with eight, tweets Mike Puma of the New York Post. Edwin Diaz, Jeurys Familia, Justin Wilson, Robert Gsellman and Seth Lugo are locks to hold down five of those spots, and Puma adds that non-roster lefties Luis Avilan and Hector Santiago are strong candidates to claim the other two slots. Both veterans signed minor league contracts with invites to Spring Training, and both have thrown quite well to open camp. That’d give manager Mickey Callaway three lefties to utilize out of the ’pen early in the season, although it wouldn’t leave the team with too much in the way of roster flexibility. With so many veteran relievers on board, the only three pitchers of that bunch who could technically be optioned to the minors would be Lugo, Gsellman and Diaz — none of whom would figure to be sent down to the minors at any point. If the Mets do eventually shift to carrying eight relievers, they’d be able to use that final ’pen slot to shuffle some fresh arms back and forth between the Majors and Triple-A Syracuse.
• Left-hander Sammy Solis was caught “completely off guard” by the Nationals’ decision to release him, the pitcher tells Richard Justice of MLB.com. Solid seemingly took the abrupt and unexpected news in good stride, thanking the organization and expressing some disappointment over having to say goodbye to longtime teammates. As manager Dave Martinez explains, the move was made with an eye toward giving Solis a chance to find another organization before the season begins. “For me, it was more about giving Sammy an opportunity to latch on with another team and get a chance to have that Spring Training elsewhere,” said Martinez. The Nats also shed $713K in salary with the move, which surely played a factor as well. The 30-year-old Solid has had a pair of unsightly seasons over the past two years, including a 2017 campaign that was shortened by elbow troubles. He maintains that he’s healthy now, though, and one would imagine that a lefty who averaged nearly 94 mph on his fastball to go along with a 12.9 percent swinging-strike rate in 2018 will garner interest — even if only on a minor league contract.
• Right-hander Pablo Lopez is making a strong case to open the season in the Marlins’ rotation, but manager Don Mattingly said this weekend that no decisions have been made as to who’ll round out the rotation behind Jose Urena and Dan Straily, per Jordan McPherson of the Miami Herald. Lopez tossed four perfect innings and picked up four punchouts in his most recent outing against a Nationals lineup featuring many regulars. He’s now allowed just one run on three hits and a walk with eight strikeouts in nine spring frames. Wei-Yin Chen’s contract — he’s owed $42MM over the next two seasons — makes him a likely candidate to get a long look, while other rotation hopefuls include Sandy Alcantara, Trevor Richards and southpaw Caleb Smith.

Jan. 5: The Mets have reportedly picked up some rotation and bullpen depth, adding veteran left-hander Hector Santiago on a minor league deal. He’ll head to Major League Spring Training as a non-roster invitee. Santiago is repped by Excel Sports.

Santiago, 31, appeared in 49 games (7 starts) for the White Sox last season, pitching to a sub-replacement-level 4.41 ERA/5.09 FIP/5.38 xFIP in 102 IP. The journeyman lefty apparently brought back one of the league’s only screwballs last season – which he featured regularly in his first stint on the Southside – in an effort to rejuvenate a floundering career. He was, yet again, quite homer-prone, surrendering 1.41 big flies per nine, a mark just slightly above his career average of 1.37 HR/9 a season.

The lefty has shown occasional aptitude for the strikeout over the course of his career, but it’s too often been offset by command issues – Santiago walked 5.29 men per nine last season, and has yet to finish a single big-league campaign with a total under 3.5 BB/9 in that category. He’ll look to compete for the 5th-starter role in the Mets’ rotation, currently occupied by Jason Vargas, with Seth Lugo, Corey Oswalt, and others – P.J. Conlon, Drew Gagnon, Chris Flexen, and more – also in the mix.

In 887 career MLB innings pitched with the ChiSox, Angels, and Twins, Santiago sports a career 4.05 ERA/4.88 FIP/5.05 xFIP.  The lefty, it should be noted, is one of the rare pitchers to outperform his fielding-independent marks in every career season, owing in large part to his stellar 77% career strand rate.

Rich Mancuso first reported that the Mets and Santiago had a deal (Twitter link), and SNY’s Andy Martino clarified that it was a minor league pact (Twitter link).
