Seattle Mariners right-handed reliever Gregory Santos (biceps) has resumed throwing at the team's spring training facility in Arizona. General manager Justin Hollander said the team doesn't "have any reason to believe there's a kinetic chain issue" between Santos' latest injury and the right-lat strain that he suffered in spring training that forced him to miss over three months. The Mariners don't have a timeline on if Santos will return before the end of the season. He left his most recent outing on July 31 with right-biceps inflammation. The 24-year-old Dominican flamethrower has only appeared in six games for the Mariners in his first year with the team and has allowed four earned runs on six hits while walking one and striking out five in 5 1/3 frames. Santos has the ability to be an intriguing late-inning arm in the bullpen, but he just hasn't been healthy this year.

Seattle Mariners right-handed reliever Gregory Santos (biceps) left his appearance early on Wednesday at Fenway Park against the Boston Red Sox with a biceps injury, according to manager Scott Servais. Santos will undergo an MRI exam on Thursday back in Seattle. The 24-year-old Dominican hurler made it through two-thirds of an inning and didn't allow a run on Wednesday in the series finale while striking out one batter before being pulled. The M's have a day off on Thursday before opening a series on Friday versus the visiting Philadelphia Phillies, and it remains to be seen if Santos will be available out of the bullpen by then. It's been a tough first year in Seattle for Santos, who entered Wednesday's contest with a 7.71 ERA and 1.50 WHIP with four strikeouts and one walk in just 4 2/3 innings pitched after missing most of the year due to injury.

Seattle Mariners right-handed reliever Gregory Santos (knee) underwent an MRI exam that "came back OK," according to manager Scott Servais. It sounds like Santos will avoid a trip to the injured list and could potentially be available out of the bullpen as soon as Saturday on the road in Chicago against the White Sox. Santos will go through pre-game exercises on Friday to test his right knee after he hurt it in the eighth inning of Wednesday's loss to the Los Angeles Angels. The 24-year-old Dominican began the year on the IL in his first year in Seattle and has pitched just four innings in 2024, allowing three earned runs on four hits. It's been a disappointing year in Seattle so far, which is partly why the M's went out and acquired reliever Yimi Garcia on Friday from the Toronto Blue Jays.

Seattle Mariners relief pitcher Gregory Santos (knee) left Wednesday's game against the division-rival Los Angeles Angels in the eighth inning after injuring his right knee. Santos had just given up a game-tying single to Willie Calhoun when he attempted to pick off pinch-runner Kevin Pillar. After getting the ball back on the mound, Santos stepped off the mound grimacing. Manager Scott Servais came out with the trainer to talk with Santos, who spent the conversation on the mound doubled over before he was pulled. Santos was making just his fourth appearance of the season for the Mariners. The 24-year-old right-hander began the season on the injured list with a lat strain, and he didn't make his Seattle debut until July 9. The Mariners should lean on Andres Munoz and Ryne Stanek for the bulk of the high-leverage work out of the bullpen if Santos' absence extends beyond Wednesday.

The Seattle Mariners reinstated right-hander Gregory Santos (lat) from the 60-day injured list on Monday and optioned right-hander Emerson Hancock to Triple-A Tacoma in a corresponding move, according to executive vice president and general manager of baseball operations Justin Hollander. A right-lat strain has kept Santos from making his Mariners debut this year to this point, but he will now join Seattle's bullpen as a key late-inning setup man. Santos features a high-90s heater and could quickly become relevant in fantasy leagues that reward points for holds. Hancock, 25, gets sent back to the farm after making a spot start on Saturday against the Blue Jays, when he gave up two runs in four innings of work. Hancock should be back with the M's again in 2024 when they're in need of more rotation help.

The Seattle Mariners transferred right-hander Gregory Santos (lat) to the 60-day injured list on Thursday to open up a roster spot for infielder Leo Rivas, whose contract was selected from Triple-A Tacoma. The 24-year-old Santos has yet to make his debut with the Mariners due to a right-lat strain, although he has started a throwing program. Now that he's officially on the 60-day IL, he won't be able to return to the Mariners bullpen until at least late May. When he's healthy, Santos will be an option as a high-leverage reliever late in games as a bridge to Andres Munoz and Ryne Stanek, and he could even enter the picture for saves. The Dominican reliever had a career-best 3.39 ERA, a 1.29 WHIP, his first five career saves, 17 walks and a career-high 66 K's in 66 1/3 relief innings in 2023 with the White Sox.

Seattle Mariners GM Justin Hollander gave updates on several injured players. Relief pitcher Matt Brash (elbow) was shut down early in spring training with elbow inflammation. Hollander reports that Brash was able to throw live batting practice this week and that he will throw another in the next day or two. The hope is that Brash will be ready to head out on rehab assignment in the coming week when Seattle heads out on their next road trip this coming Wednesday after they finish the series with the Cincinnati Reds. Another high-leverage arm, Gregory Santos (lat), is playing catch from 75 feet out right now. He's a little behind Brash at this point, according to Hollander. The next progression is to throw at 105 feet in the next week and then progress to pitching off a mound after that. Santos has been out all season with a lat strain. At this time, Ryne Stanek and Andres Munoz continue to lead the Mariners' bullpen.

Seattle Mariners right-hander Matt Brash (elbow) threw a bullpen session in Arizona on Monday and mixed in some sliders. He hasn't started throwing at maximum effort yet but is making steady progress. Meanwhile, righty Gregory Santos' (lat) MRI exam came back clean and he began light baseball activities on Monday. There aren't any specific timetables for the return of Brash or Santos, but they are making progress. The 25-year-old Brash appears to be ahead of Santos in his recovery from injury. When healthy, both pitchers are expected to be key contributors in Seattle's bullpen in late-inning situations in front of closer Andres Munoz. Brash was a workhorse for the M's in 2023 with a career-high 70 2/3 innings pitched while finishing second among qualified relievers with 107 strikeouts.

Seattle Mariners relief pitcher Gregory Santos (lat) is scheduled to undergo an MRI on Thursday, per the Seattle Times' Ryan Divish. Santos has been dealing with a lat strain this spring which has slowed his progress on and off. The 24-year-old will continue his throwing program if the MRI comes back clean. While he may not provide a ton of fantasy value upon his return to the team, the Mariners will welcome him back as their bullpen depth is currently short with Matt Brash (elbow) dealing with right elbow inflammation.

Seattle Mariners reliever Gregory Santos (lat) will not be ready for Opening Day after he suffered a lat strain and will be shut down for a few days, per manager Scott Servais. Santos has been dealing with a lat issue this spring and was reportedly progressing well in his throwing program but has apparently suffered a setback and will not be ready for the start of the regular season. Acquired from the White Sox this winter, the right-hander worked to a 3.39 ERA across 60 starts as a rookie in the 2023 season. He was likely in line for some holds opportunities with fellow reliever Matt Brash also on the sidelines, but his fantasy value takes a notable hit with his injury to begin the season.

Seattle Mariners pitcher Gregory Santos (lat) is progressing well early in his throwing program, according to M's general manager Justin Hollander. Santos was cleared to begin a throwing program on Tuesday and the early reports are positive at this time. The 24-year-old was acquired from the Chicago White Sox on Feb. 3 for two minor leaguers and a draft pick. He enjoyed a nice rookie season in the bigs in the 2023 campaign when he worked to a 3.39 ERA and a 17% K-BB% across 60 appearances, even locking down five saves. He is slated for late-inning work again with the Mariners in 2024 but behind closer Andres Munoz. However, the unstable injury situation with Matt Brash could yield Santos some holds if Brash were to miss notable time.

Seattle Mariners right-hander Gregory Santos (lat) will begin his throwing program on Tuesday. The 24-year-old was acquired this offseason in a trade with the Chicago White Sox after he impressed in 60 appearances on the south side in his rookie campaign in 2023. Santos worked to a 3.39 ERA in his 66 1/3 innings of work but also posted a 2.65 FIP and allowed just two home runs on the season while posting a tiny 0.27 HR/9 clip. The Mariners have Andres Munoz and Matt Brash as the key late-inning arms at the back end of their bullpen, meaning Santos' chances at saves and holds could be limited. He is best left off the fantasy radar barring a notable injury to either Munoz or Brash.

Seattle Mariners manager Scott Servais said that relief pitcher Gregory Santos (lat) is progressing and will start ramping up his throwing program in the coming days at spring training. Santos reported right-lat soreness early in camp but could still be ready for Opening Day as long as he doesn't have a setback once he resumes throwing. The 24-year-old was acquired from the Chicago White Sox in a trade this offseason and is expected to serve in some sort of setup role for the M's in 2024 in his first year in Seattle. Unless you're in a really deep holds league, Santos probably shouldn't be on your fantasy radar. In 66 1/3 relief innings for Chicago last year, Santos had a respectable 3.39 ERA and 1.30 WHIP with 66 strikeouts and 17 walks.

Seattle Mariners right-hander Gregory Santos (lat) is a little bit behind the other pitchers in spring training due to a right-lat that has recently surfaced. Santos won't be able to throw off a mound right away in camp. The 24-year-old also dealt with right-elbow soreness last year and could be in danger of opening the 2024 regular season on the injured list. Santos came to Seattle this offseason in a trade from the Chicago White Sox and figures to serve in a setup role when healthy. The Dominican reliever made a career-high 60 appearances out of Chicago's bullpen last year and was solid with a 3.39 ERA and 1.29 WHIP with his first five career saves, 17 walks and 66 strikeouts in 66 1/3 innings. Unless injuries in the back of Seattle's bullpen open up save chances for Santos, he's unlikely to have much fantasy appeal in 2024.

The Seattle Mariners have acquired relief pitcher Gregory Santos from the Chicago White Sox in exchange for right-hander Prelander Berroa, outfielder Zach DeLoach, and the 69th pick in the 2024 MLB Draft, according to Jeff Passan of ESPN. Santos made a handful of appearances between 2021 and 2022 but truly emerged last year, amassing a 3.39 ERA, 8.95 K/9, and 2.31 BB/9 over the course of 66.1 innings before a late-season shoulder injury. Now healthy, he was in the mix to be the White Sox' closer and should maintain a high-leverage role in Seattle.

Chicago White Sox relief pitcher Gregory Santos (elbow) is working out in Arizona and has had good medical reports, according to general manager Chris Getz. The team's goal is to have Santos ready for the start of the 2024 season, but he just started a throwing program, so he might not be full-go for the start of spring training. The 24-year-old is projected to share the closer's role next year with left-hander Garrett Crochet, but first Santos must fully recover after closing the 2023 campaign on the injured list with right-elbow inflammation. The White Sox are in full rebuild this offseason, though, so the Chicago bullpen may not yield many saves for Santos and company. The Dominican reliever had a 3.39 ERA (2.65 FIP) and 1.29 WHIP with his first five career saves and 66 K's in 66 1/3 relief innings this past season in his first full MLB season after debuting in 2021.

The Chicago White Sox placed right-hander Gregory Santos (elbow) on the 15-day injured list on Wednesday with right-elbow inflammation and reinstated left-hander Garrett Crochet (shoulder) from the 15-day injured list in a corresponding move. The move ends Santos' 2023 season. The 24-year-old reliever hadn't pitched since Sept. 16 and will now be ineligible to return this year. Santos was not good in his role as the team's closer in the second half of the season, and he posted a rough 6.00 ERA, 1.47 WHIP and three saves in six chances in the second half. The White Sox's bullpen just isn't really a place that fantasy managers chasing saves down the stretch should be looking at. With Santos now out, Bryan Shaw and Aaron Bummer figure to share save opportunities to close out the year.

Chicago White Sox relief pitcher Gregory Santos blew his fourth save of the season in Tuesday's 7-6 loss to the Royals. Santos entered the game to pitch the bottom of the ninth up by one. The leadoff hitter reached on a throwing error. He then allowed a single, got the first out at second on a groundout, allowed a game-tying RBI double, got the second out on a lineout, intentionally walked the bases loaded, and balked in the winning run. The 24-year-old has now converted half of his save opportunities this season with a 3.18 ERA and a 9.10 K/9 rate. While he has pitched well overall and may see whatever save opportunities the White Sox get, the low volume limits his fantasy value, even in deeper roto leagues.

Chicago White Sox relief pitcher Gregory Santos earned his fourth save of the season in Tuesday's 5-3 win over the Cubs. Santos entered the bottom of the eighth inning up by one with one out and the bases empty. He got the final two outs on a groundout and a strikeout and stayed on to pitch the ninth, turning in a 1-2-3 inning with another two strikeouts. The 23-year-old has pitched well all season and could continue to see increasing high-leverage opportunities now that Kendall Graveman is no longer on the team. The White Sox may not see a ton of save opportunities, but Santos' 2.53 ERA and 9.00 K/9 rate make him worth a look in deeper roto leagues at this time.

The Chicago White Sox reinstated right-handed reliever Gregory Santos from the bereavement list on Tuesday and optioned right-hander Edgar Navarro to Triple-A Charlotte in a corresponding move. Santos will return to the late-inning bullpen mix in Chicago after being away from the club since Saturday. With Santos away, Bryan Shaw picked up a save on Monday, a day after Jimmy Lambert recorded a save for the Pale Hose on Sunday. The 23-year-old Santos picked up his first two career saves in July and could be the favorite for the majority of the save opportunities the rest of the season in Chicago now that Liam Hendriks (elbow) is done for the rest of the year. Fantasy managers desperate for saves should speculate on Santos in deeper leagues.
