Penrod isn't expected to need surgery on his injured left elbow, Chris Cotillo of MassLive.com reports.

Penrod has been dealing with a sore left elbow and got an MRI on Thursday. The results of the test were encouraging, as the lefty reliever doesn't appear to be slated to go under the knife. However, manager Alex Cora said Saturday that Penrod will be "out a while," which could impact his chances of making the Opening Day bullpen.

Burr has been managing shoulder tendinitis and "backed off" throwing for a few days, though he's playing catch Saturday, Keegan Matheson of MLB.com reports.

Burr may be able to build back up quickly and doesn't seem to be at risk of missing time to start the regular season. The veteran reliever is slated for a middle-relief role in Toronto's bullpen for the coming campaign after posting a 4.13 ERA, 1.26 WHIP and 47:12 K:BB over 32.2 innings in 34 games during the 2024 season.

Soriano (arm) is scheduled to start Tuesday's Cactus League game against the Padres.

Soriano ended last season on the injured list with arm issues, which prompted an MRI on his elbow and shoulder in September. The testing came back clean, and Soriano's inclusion in the spring rotation suggests he's back to full strength. If he makes it through camp unscathed, Soriano will likely be part of the Angels' starting rotation to begin the 2025 regular season after he put up a 3.42 ERA and 1.20 WHIP over 113 innings last year.

Sisk is dealing with an illness that has been going around the Royals' clubhouse, Anne Rogers of MLB.com reports.

Sisk was originally expected to pitch in the Royals' Cactus League game versus the Rangers on Friday, but his illness kept him out of action. The 27-year-old southpaw was added to the 40-man roster in November after posting a 1.56 ERA and 1.03 WHIP across 57.2 innings at Triple-A Omaha, and he'll make his spring debut once he's feeling better.

Marsh (shoulder) is slated to throw a bullpen session Friday, MLB.com reports.

Marsh first experienced tightness in his right shoulder during his offseason throwing program and has been brought along slowly early in camp. Returning to mound work Friday offers him time to ramp up ahead of Opening Day, although he probably can't afford any setbacks. Marsh is competing for the final spot in the Royals' rotation.

Swanson (forearm) threw 10 pitches off a mound Tuesday, MLB.com reports.

Swanson is a little behind at the beginning of camp due to right forearm fatigue. He was never totally shut down though, and now that he's progressed to mound work, he could build up quickly. Swanson is on track to be ready for Opening Day, and while he's coming off a rough 2024 campaign, the right-hander is out of minor-league options and should have a spot in the Blue Jays' big-league bullpen.

The Blue Jays signed Yarbrough to a minor-league contract Thursday with an invite to spring training, Robert Murray of FanSided.com reports.

Yarbrough made his first appearances with the Blue Jays in August after being dealt by the Dodgers in late July. With Toronto, he recorded a 2.01 ERA across 31.1 innings in 12 games. The southpaw was used out of the bullpen in all 12 of his appearances and will presumably fill a piggyback or long-relief role if he gets onto the MLB roster this year.

Hamilton (calf) threw a live batting practice session Thursday, Pete Caldera of The Bergen Record reports.

The right-hander faced off against Austin Wells, Aaron Judge, Jasson Dominguez and Cody Bellinger in the live session. The 29-year-old reliever didn't make any appearances after injuring his calf in Game 3 of the Yankees' loss to the Guardians in the ALDS last fall, but his ability to face hitters early on during spring training suggests he's fully healthy.

Hader worked this offseason on limiting his movements before his windup in an effort to not tip his pitches, Brian McTaggart of MLB.com reports.

Houston failed to make the ALCS for the first time in eight years, with Hader giving up a three-run double to Andy Ibanez as the Tigers were able to break open Game 2 of the American League Wild Card Series and eliminate the Astros early. During the regular season, Hader logged a 3.80 ERA, 0.96 WHIP, 105 strikeouts and 34 saves in 71 innings. In addition to trying to cut down on any pre-windup tells, Hader said he is working on making his changeup a bigger part of his arsenal, although that's something he's wanted to do for years, by his own admission, so it's too early to say this will actually be the year he can rely on anything besides his sinker and slider. Regardless of whether he has a more reliable third pitch, Hader should once again rank near the top of the majors in saves and strikeouts among relievers.

The Red Sox signed Moore to a minor-league contract Thursday that includes an invitation to spring training, Rob Bradford of WEEI.com reports.

The Red Sox were looking for some left-handed relief depth with Zach Penrod going down with an elbow injury. Moore is coming back from an injury of his own, having missed the final month of last season with a left forearm strain. However, the southpaw has been throwing this offseason without any apparent issues, per Bradford. Moore held a 5.03 ERA and 41:26 over 48.1 frames with the Angels in 2024, but he was very effective from 2022 to 2023 with a 2.20 ERA and 27.4 percent strikeout rate. If heathy, the 35-year-old should have a good shot to make Boston's Opening Day roster.
