The Athletics acquired Johnson from the Phillies on Monday in exchange for outfielder Colby Thomas.

Johnson has yet to find much success in the majors, putting up a 7.18 ERA and 37:21 K:BB over 31.1 frames covering parts of three seasons. However, he's a hard thrower who holds a 2.17 ERA and 40:11 K:BB across 29 frames this season at Triple-A Lehigh Valley. Johnson might get a chance to pitch high-leverage innings as part of a patchwork Athletics bullpen.

The Blue Jays acquired Klein, left-hander Dasan Hill, infielder Dameury Pena and $250,000 in international bonus pool space from the Twins on Monday exchange for right-hander Jeff Hoffman on Monday, Mark Feinsand of MLB.com reports.

Klein appeared in three games for Minnesota this season, but spent most of his time with Triple-A St. Paul. At the Triple-A level, the 24-year-old has recorded a 5.91 ERA, 1.52 WHIP and 74:34 K:BB in 64 innings this season. The right-hander will report to Triple-A Buffalo to begin his time in the Toronto organization.

The Twins acquired Hoffman from the Blue Jays on Monday in exchange for Dasan Hill, John Klein and Dameury Pena, Ben Nicholson-Smith of Sportsnet.ca reports.

Hoffman lost his closer job with the Blue Jays early on this season, but he's been dominant since the beginning of June, turning in a 1.21 ERA and 30:8 K:BB over 22.1 innings. Yoendrys Gomez has fared well as the Twins' closer, but he will have competition with Hoffman for saves now. Hoffman is under contract for 2027 with a salary of $12.67 million.

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.
