The Red Sox acquired Miller and outfielder Carlos Gutierrez from the Giants on Monday in exchange for infielder Marcelo Mayer (forearm), Jeff Passan of ESPN.com reports.

Miller will make his way to Boston in the midst of one of the more dominant stretches of his career. Dating back to June 12, the 28-year-old has delivered 14 consecutive scoreless appearances. The left-hander appeared to have worked his way into the Giants' unsettled closer picture, but with the move to Boston, he'll operate as a setup man in front of Aroldis Chapman.

The Rays acquired Wells from the Orioles on Monday in exchange for right-hander Michael Forret, Marc Topkin of the Tampa Bay Times reports.

Wells boasts a 2.67 ERA, 0.96 WHIP and 53:13 K:BB over 54 innings out of the Baltimore bullpen this season. He should handle a setup role for the Rays, who will have him under club control through the 2027 campaign.

The Royals transferred Seabold (lat) from the 15-day injured list to the 60-day IL on Monday.

Seabold will give up his spot on the 40-man roster to right-hander Nolan Hoffman, whom the Royals acquired in a trade with the Phillies. Since Seabold was initially placed on the IL on July 1, he won't be eligible for activation until Aug. 30. Seabold is currently rehabbing in Arizona while he recovers from the right lat strain, and a potential target date for his return likely won't be known until he heads out on a rehab assignment.

The Royals acquired Hoffman from the Phillies on Monday in exchange for Manuel Colon.

Hoffman had been booted off the Phillies' 40-man roster earlier Monday, but he'll now join a new 40-man roster in Kansas City. The right-handed reliever has logged a 4.72 ERA and 40:18 K:BB over 34.1 innings at the Triple-A level this season and has given up two runs in 4.2 frames in the majors in 2026.

The Rays recalled Grove from Triple-A Durham on Monday.

Grove will give the Rays a fresh arm to round out their bullpen after Craig Kimbrel was designated for assignment and Alex Cook was optioned to Triple-A earlier Monday to create room on the roster for the club's recent trade additions. The right-hander has been up with the Rays on two other occasions this season but made his lone appearance with the big club June 27, when he struck out four over three scoreless innings in a win over the Diamondbacks.

The Yankees recalled Castro from Triple-A Scranton/Wilkes-Barre on Monday.

Castro has allowed one run with a 4:0 K:BB in 2.2 innings out of the Yankees bullpen this season. He'll be used in middle relief.

The Rays optioned Cook to Triple-A Durham on Monday.

Cook allowed three runs with a 2:2 K:BB over 3.2 innings in his first two major-league appearances. He's being sent down in order to free up a spot on the active roster for right-hander Freddy Peralta, who was acquired from the Mets on Sunday.

The Royals acquired Duran from the Dodgers on Monday in exchange for Kris Bubic (elbow/shoulder), Mark Feinsand of MLB.com reports.

Duran has spent the entirety of the 2026 season at Triple-A Oklahoma City, where he's collected a 3.38 ERA and 61:28 K:BB over 42.2 innings. The 25-year-old made one appearance in the majors with the Athletics in 2025, yielding three runs while recording only one out.

The White Sox designated Davitt for assignment Monday.

The move clears a spot on the 40-man roster for outfielder Brenton Doyle, who was acquired from the Rockies on Monday. Davitt has allowed one run over two innings during his brief time in the majors this season and holds a 6.22 ERA and 64:25 K:BB across 59.1 frames at Triple-A Charlotte.

The Rangers acquired Macko from the Blue Jays on Monday in exchange for Josh Smith and Josh Stephan, Ken Rosenthal of The Athletic reports.

Macko has made a full-time move to the bullpen this season, posting a 4.91 ERA and 23:10 K:BB over 22 innings for the Blue Jays and a 4.07 ERA and 29:11 K:BB across 24.1 frames with Triple-A Buffalo. The 25-year-old had been optioned to the minors last week, but it's unclear whether the Ranger intend to put him on the big-league roster or send him to Triple-A Round Rock.
