  • Mariners' Gregory Santos: Ups throwing distance

    Santos (lat) recently upped his throwing distance to 120 feet, MLB.com reports.

    A recent shift to the 60-day IL didn't impact Santos' return timeline, as he was never expected to be able to make his season debut before late May. That timeframe appears to still remain realistic, and he's slated to continue throwing at the 120-foot distance throughout this week before upping his intensity again.

  • Mariners' Gregory Santos: Shifts to 60-day IL

    The Mariners transferred Santos (lat) from the 15-day injured list to the 60-day IL on Thursday.

    The transaction was made in order to free up a spot on the 40-man roster for infielder Leonardo Rivas, whose contract was selected from Triple-A Tacoma. Santos is in the midst of a throwing program as he works his way back from a right lat strain, but the Mariners are proceeding conservatively with him. He won't be eligible to make his season debut until late May.

  • Mariners' Gregory Santos: Throwing from 75 feet

    Santos (lat) has progressed to throwing from 75 feet and could soon up his distance to 105 feet, SeattleSports.com reports.

    General manager Justin Hollander noted Friday that the hope is Santos will be able to boost that distance at some point in the coming week, after which he'd progress to throwing off a mound. Hollander added the team would continue to be "somewhat conservative" with the right-hander's recovery, which eventually is expected to culminate in a lengthy rehab assignment given he missed the entirety of the Cactus League slate.

  • Mariners' Gregory Santos: Inching toward mound work

    Santos (lat) has started a throwing program and is getting closer to beginning mound work, MLB.com reports. "I don't want to get into much more detail on timelines like that, but it has been very positive," manager Scott Servais said.

    Servais added that Santos is a "little bit" behind fellow sidelined reliever Matt Brash (elbow) in terms of his progress, but the Mariners' skipper seems encouraged overall by Santos' trajectory. Santos never did see Cactus League action this spring, so he'll be in line for what could be a full-length rehab assignment whenever he reaches that point in his recovery.

  • Mariners' Gregory Santos: Plays catch Monday

    Santos (lat) played catch Monday after an MRI showed improvement, Shannon Drayer of Seattle Sports 710 AM reports.

    Santos first felt tightness in his right lat at the beginning of spring training and has had trouble getting over the hump. It's certainly a good sign that he's throwing again, but the reliever has a long ways to go before a timeline to return is established.

  • Mariners' Gregory Santos: Shelved with lat strain

    The Mariners placed Santos (lat) on the 15-day injured list Thursday.

    Santos was shut down March 11 after he was diagnosed with a right lat strain. He was scheduled to undergo an MRI on Thursday, and if the testing reveals that the inflammation in his lat has subsided, Santos could be cleared to start at throwing program in the coming days. Whenever he's able to make his Seattle debut, the right-hander will likely deployed as a setup man in front of closer Andres Munoz.

  • Mariners' Gregory Santos: MRI date set

    Santos (lat) will undergo an MRI on Thursday and the results will determine the next steps in his recovery, MLB.com reports.

    If the inflammation in Santos' lat has subsided sufficiently, the Mariners will begin mapping out a throwing program. The right-hander still projects to be sidelined for several more weeks, as he'll need to eventually complete a rehab assignment at the minor-league level before being deemed ready for activation.

  • Mariners' Gregory Santos: Slated for MRI

    Santos (lat) will receive an MRI within the next few days, Ryan Divish of The Seattle Times reports.

    Santos strained his right lat during a bullpen session earlier in spring camp, and his MRI will determine if the inflammation has gone down enough for him to resume his throwing program. Santos will begin the year on the injured list, but his absence isn't expected to extend more than a month or two into the regular season.

  • Mariners' Gregory Santos: Not yet in rehab routine

    Santos, who suffered a mild lat strain Monday, is still "waiting to get things calmed down" before officially beginning a rehab routine, MLB.com reports.

    The update comes directly from manager Scott Servais, who's counting on Santos to play a key seventh- and eighth-inning role this season. Santos has already been ruled out for Opening Day, however, and it's likely extra caution is taken with the restart date of his baseball activities considering he's also already dealt with a shoulder problem this spring.

  • Mariners' Gregory Santos: Out for opener with lat strain

    Santos will not be ready for Opening Day after an MRI revealed a mild right lat strain, Shannon Drayer of Seattle Sports 710 AM reports.

    Santos had been slated for a bullpen session Monday, but that was scratched after he felt a pinch in his lat area. Testing has revealed a minor strain, and he will presumably be shut down from throwing for a while. Santos is slated to serve in a setup role once he's healthy, but he now joins Matt Brash (elbow) on the shelf for the time being.

  • Mariners' Gregory Santos: Throws bullpen Friday

    Santos (lat) threw a light bullpen Friday, Shannon Drayer of 710 ESPN Seattle reports.

    It was an important benchmark for Santos as he works back from being shut down with lat soreness in mid-February. Drayer notes the session appeared to go well, but there's not yet an indication of when the Mariners may be willing to allow Santos to test himself out in Cactus League action.

  • Mariners' Gregory Santos: Could throw off mound soon

    Santos (lat) will long-toss from 150 feet Tuesday and might be cleared to throw off a mound in a few days, Ryan Divish of The Seattle Times reports.

    Santos developed right lat soreness early on in camp and resumed throwing a week ago. The reliever should have time to ramp up for Opening Day if he can avoid setbacks, but it's going to be close.

  • Mariners' Gregory Santos: Checks out well after throwing

    Mariners manager Scott Servais said Santos (lat) checked out well after playing catch Tuesday, Shannon Drayer of Seattle Sports 710 AM reports.

    According to Servais, Santos was throwing hard while playing catch, but he's still not been cleared to advance to mound work as he looks to shake off right lat soreness. Santos could get the green light to throw a bullpen session after he plays catch again later this week.

  • Mariners' Gregory Santos: Resuming throwing program Tuesday

    Santos (lat) will resume a throwing program Tuesday, Ryan Divish of The Seattle Times reports.

    Santos has been slowed this spring by some soreness in his right lat, which cropped up during an early bullpen session. He's made the necessary progress to be cleared to throw again and will presumably start with some flat-ground work before progressing to the mound and facing hitters. Santos has time to be ready for Opening Day but can't afford a setback.

  • Mariners' Gregory Santos: Should start throwing soon

    Mariners manager Scott Servais said Monday that Santos (lat) is progressing and will begin ramping up his throwing program in the coming days, Ryan Divish of The Seattle Times reports.

    Seattle isn't yet ruling Santos out for Opening Day as he works through right lat soreness, but he'll likely need to navigate his upcoming throwing program without setbacks in order to guarantee that he avoids a stint on the injured list to begin his inaugural campaign with the Mariners. Santos was acquired from the White Sox earlier this month with the expectation that he would be a dependable part of the bridge to projected closer Andres Munoz, coming off a 2023 campaign in which he compiled a 3.39 ERA, 1.30 WHIP and a 66:17 K:BB in 66.1 innings.

  • Mariners' Gregory Santos: Nursing lat injury

    Santos is dealing with soreness in his right lat/teres major area, Ryan Divish of The Seattle Times reports.

    Santos ended last season with right elbow soreness, but now he's got a new injury which cropped up following a bullpen session this spring. It's not clear at this juncture whether the setback might be significant enough to delay his start to the season. Santos was acquired via trade from the White Sox earlier this month and, if healthy, is slated to serve as a setup man.

  • Mariners' Gregory Santos: Behind schedule

    Santos (elbow) will be a bit behind schedule at the start of Mariners camp, Ryan Divish of The Seattle Times reports.

    Santos ended last season with a right elbow injury and will be held back from mound work for a while this spring. Seattle felt confident enough in the reliever's health to trade for him earlier this month, so he doesn't seem to be in any danger of not being ready for Opening Day.
