Rivera (0-1) took the loss Wednesday against the Orioles, allowing four runs on three hits and two walks in two-thirds of an inning. He struck out one.

Rivera couldn't escape a laborious opening frame in the nightcap of Wednesday's twin bill, tossing 41 pitches before his outing mercifully came to an end. Ranger Suarez (groin/illness) is on the cusp of coming off the injured list after being pushed back from starting Wednesday, so Rivera may not be sticking around on the major-league roster much longer. The rookie left-hander has yet to complete four frames in any of his three starts for Boston, recording a 9.45 ERA and 7:6 K:BB across 6.2 innings.

The Yankees optioned Castro to Triple-A Scranton/Wilkes-Barre on Wednesday.

Castro struck out the only two batters he faced during New York's loss in the first half of Wednesday's twin bill against Pittsburgh, but he'll now end up as the roster casualty necessary to make room for Max Fried's (elbow) return from the IL. Castro boasts a 2.39 ERA and 0.88 WHIP across 26.1 innings in the minors, so he could soon get another opportunity with the Yankees if his performance holds at Triple-A.

Quantrill is expected to work in bulk relief behind opening pitcher Tyler Alexander during Wednesday's game against the White Sox, Evan Grant of The Dallas Morning News reports.

The White Sox will roll out a starting lineup featuring three left-handed batters in the top four spots, so the left-handed Alexander will likely work the first inning or two in an effort to neutralize those hitters. Quantrill is then expected to enter the game once Alexander exits, which could aid Quantrill's chances of coming away with a win. Quantrill had started in each of his last five appearances, going 0-2 with a 4.29 ERA, 1.33 WHIP and 12:4 K:BB across 21 innings.

The Orioles recalled Walker from Triple-A Norfolk on Wednesday.

Walker has been appointed as the club's 27th man for the second game of Wednesday's doubleheader in Boston. The southpaw has permitted three runs with a 7:2 K:BB over six innings during his time in the Orioles' bullpen this season. Walker will likely be dispatched to Norfolk following the twin bill.

The Red Sox recalled Gamboa from Triple-A Worcester on Wednesday.

Gamboa will serve as the 27th man for the second game of Wednesday's doubleheader versus the Orioles. The lefty has logged a 2.25 ERA and 5:4 K:BB in eight innings for Boston this season and could offer some length out of the bullpen in Wednesday's nightcap, if needed.

Rivera will start the second game of Wednesday's doubleheader versus the Orioles, Christopher Smith of MassLive.com reports.

The Red Sox had left open the possibility of Ranger Suarez (groin/illness) coming off the injured list to start Wednesday's nightcap, but they'll hold Suarez back for now and give Rivera another turn. Rivera has allowed three runs with a 9:4 K:BB over 9.1 frames covering two starts and one relief appearance for Boston this season. He's thrown 64 pitches in both of his starts and not lasted more than 3.2 innings in either outing, so Rivera is unlikely to offer significant length Wednesday.

Chapman secured the save in Game 1 of Wednesday's doubleheader against Baltimore, allowing one hit and one walk in a scoreless ninth inning.

Chapman threw only six of his 13 pitches for strikes and failed to record a strikeout, so he didn't have his best stuff on the hill Wednesday. Even so, the veteran southpaw successfully converted his seventh consecutive save and hasn't given up a run in six straight outings. Through 32.2 innings this year, Chapman has a 1.93 ERA, 1.26 WHIP and 40:16 K:BB with 23 saves in 25 attempts.

The Athletics recalled Barnett from Triple-A Las Vegas on Wednesday.

Barnett is grabbing the roster spot vacated by the injured J.T. Ginn (finger). He's also a candidate to take Ginn's rotation spot even though all 13 of his appearances in the majors this season have been in relief. Barnett has made 10 starts in 2026 with Las Vegas, posting a 4.34 ERA and 42:26 K:BB over 45.2 frames.

The Royals acquired Pearson from the Astros on Wednesday in exchange for Max Martin.

Pearson had been designated for assignment by Houston, but he will now join a 40-man roster in a new organization. The hard-throwing righty holds a 3.60 ERA, 1.40 WHIP and 16:12 K:BB in 20 innings in the majors this season. Pearson does not have any minor-league options remaining, so he will join the Royals' bullpen.

Smith struck out one in a perfect ninth inning Tuesday to record his 29th save of the season in a 5-2 win over the Twins.

The 27-year-old closer fanned Kody Clemens as he extended his MLB saves lead, with the Padres' Mason Miller, the Rays' Bryan Baker and the Cardinals' Riley O'Brien tied for second with 25. Smith has allowed an earned run in only one of his last 10 appearances, and on the season he's produced a 2.72 ERA, 1.06 WHIP and 66:11 K:BB over 46.1 innings.
