Kelly was optioned to Triple-A Worcester on Tuesday.

Kelly got the call Sunday and gave up two runs (one earned) on one hit and one walk with zero strikeouts in two innings against the Orioles. Richard Fitts (pectoral) was activated in a corresponding move.

Penrod (elbow) was activated from the 60-day injured list Tuesday and optioned to Triple-A Worcester, Chris Cotillo of MassLive.com reports.

Penrod opened the year on the IL with a left elbow UCL sprain and he was activated after one scoreless rehab appearance Saturday in the Florida Complex League. The 27-year-old lefty will knock some rust off at Triple-A before potentially being an option in the majors later this summer.

The Guardians optioned Cantillo to Triple-A Columbus on Tuesday.

The left-hander has been solid in relief for Cleveland this year with a 3.81 ERA across 28.1 innings, but he'll head to the minors after giving up a run over three innings Monday versus the Dodgers. Hunter Gaddis (personal) was reinstated from the bereavement list in a corresponding move. According to Tim Stebbins of MLB.com, Cantillo will be stretched out as a starter with Columbus.

The Guardians reinstated Gaddis (personal) from the bereavement list Tuesday.

The right-hander stepped away from the team for a few days for personal reasons but is back on the active roster ahead of Tuesday's matchup with the Dodgers. Gaddis has been a key bullpen piece for Cleveland this season with 13 holds and a 0.86 ERA, 1.14 WHIP and 29:8 K:BB across 21 innings.

The Athletics designated Krook for assignment Tuesday.

The left-hander was optioned to Triple-A Las Vegas on Thursday and has now lost his place on the 40-man roster. Krook will likely remain with Vegas if he passes through waivers unclaimed.

The Athletics acquired Newcomb from the Red Sox on Tuesday in exchange for cash considerations.

The left-hander was designated for assignment by Boston over the weekend, but he found a new home on an MLB roster. Newcomb opened the season in the Red Sox's rotation before shifting to a long-relief role, and overall he had a 3.95 ERA, 1.76 WHIP and 41:17 K:BB across 41 innings. The 31-year-old spent the 2023 and 2024 campaigns with the Athletics but pitched in just 14 games (two starts).

Kahnle tossed a scoreless inning of relief in Monday's 3-1 win over the Giants to record his sixth hold of the season.

Kahnle is now second on the team with his six holds, and he also has six saves, which is tied with Will Vest for the team lead. It was Vest who earned the save Monday, working the ninth inning after Kahnle cruised through the eighth on only 10 pitches. The two veteran righties are locked into a closer-by-committee arrangement for the time being, giving them both some fantasy value but also limiting their upside. Kahnle has earned the right to close out games, as he's now sitting with a 1.66 ERA, 0.88 WHIP and 20 strikeouts across 21.2 innings this year.

De Los Santos notched a hold against the Angels on Monday, striking out three batters while allowing one hit over 1.1 scoreless innings.

De Los Santos entered in the seventh frame and retired all three batters he faced in that inning, striking out Jorge Soler and Logan O'Hoppe. The right-hander continued into the eighth and gave up a leadoff single but then struck out Chris Taylor before exiting. De Los Santos has pitched well in a limited sample size while with the big club this season, allowing just two runs over 11 innings covering eight appearances. However, he's posted an unimpressive 9:5 K:BB and has a 1.45 WHIP, so he seems to have been a bit lucky so far in avoiding giving up runs.

Yarbrough (2-0) allowed a run on two hits and a walk while striking out seven over six innings to earn the win Monday over the Angels.

Yarbrough's sixth pitch of the game was taken 440 feet out to center field by Zach Neto. That would be Yarbrough's only blemish in an otherwise stellar start, his longest outing of 2025. He's now at a 3.06 ERA, 1.05 WHIP and 35:11 K:BB across 35.1 innings over 12 appearances (four starts) this season. He's tentatively projected for a road start versus the Dodgers this weekend, though the Yankees skipped his turn the last time the schedule allowed them to get by with a four-man rotation, so it's not set in stone that he'll get a chance to face his former team.

Vest picked up the save in Monday's 3-1 win over the Giants, surrendering one hit and striking out one.

In what has been a closer-by-committee of sorts in Detroit to start the season, it was Vest who was asked to get the final three outs against the Giants on Monday, earning his sixth save of the season. That pulls him even in saves on the Tigers with fellow high-leverage arm Tommy Kahnle. The 29-year-old Vest has now recorded six straight scoreless outings, allowing just three hits with five strikeouts over six innings during the streak.
