MLB Player News

The Brewers acquired May and JoJo Romero (abdomen) from the Cardinals on Monday, Ken Rosenthal of The Athletic reports.

May has turned in a nice 2026 campaign, collecting a 4.38 ERA and 106:35 K:BB over 109 innings covering 21 starts for the Cardinals. The right-hander is earning $12.5 million this season and is an impending free agent.

The Pirates acquired Weaver and cash considerations from the Mets on Monday in exchange for shortstop Sammy Stafura, Jorge Castillo of ESPN.com reports.

Weaver receives a potentially big boost in fantasy value with a move to Pittsburgh, where he could be the favorite to serve as the Pirates' closer. The righty reliever has posted a 1.84 ERA and 45:11 K:BB over 44 innings this season for the Mets. Weaver is under contract for 2027 as well, with a salary of $12.5 million.

The Cubs acquired Detmers from the Angels on Monday, Michael Cerami of Bleacher Report reports.

The Cubs previously traded for Kevin Gausman and have further bolstered their rotation with the addition of Detmers, who has logged a 4.03 ERA and 145:38 K:BB across 125 innings covering 22 outings for the Angels this season. The 27-year-old left-hander will be under team control through the end of the 2028 campaign.

The Giants acquired Mendez (undisclosed) and shortstop Joniel Hernandez from the Padres on Monday in exchange for left-hander Robbie Ray, Alex Pavlovic of NBC Sports Bay Area reports.

San Diego added Mendez to its 40-man roster over the winter, but the 24-year-old righty has yet to pitch above the Double-A level and probably won't be a realistic candidate to make his MLB debut until 2027. Mendez turned in a 4.93 ERA, 1.46 WHIP and 38:17 K:BB in 34.2 innings over 11 starts with Double-A San Antonio this season before landing on the 7-day injured list June 27 due to an unspecified injury. He was cleared to begin a rehab assignment in the Midwest League last week and could soon be ready to come off the IL and report to Double-A Richmond with his new organization.

The Nationals recalled Ortiz from Triple-A Rochester on Monday.

The 24-year-old will join the big club ahead of its four-game series in Philadelphia and is likely to settle into the strong side of a platoon at first base with Andres Chaparro (head), after the Nationals traded Luis Garcia to the Yankees on Sunday. Ortiz previously made his MLB debut in the Nationals' final game before the All-Star break but has otherwise spent the entire 2026 campaign at Triple-A. He's kept his strikeout rate at a manageable 19.5 percent and has produced a .244/.348/.497 slash line with 18 home runs across 365 plate appearances with Rochester.

The Marlins acquired Kisting and infielders Brayden Taylor and Adrian Santana from the Rays on Monday in exchange for catcher Liam Hicks, Joel Sherman of the New York Post reports.

Kisting, 23, has logged an impressive 1.67 ERA and 96:18 K:BB over 86 innings with High-A Bowling Green this season. It's the second time since last offseason that Kisting has been traded, as he went from the Twins to the Rays in November in exchange for right-hander Eric Orze.

The Dodgers acquired Bubic (shoulder/elbow) from the Royals on Monday in exchange for right-hander Carlos Duran, Jeff Passan of ESPN.com reports.

Though the Dodgers don't appear to have any room in the rotation after acquiring Tarik Skubal over the weekend and with Blake Snell (elbow) and Tyler Glasnow (back) nearing returns from the injured list, the organization didn't pass up on the chance to add another talented arm in Bubic to its deep stable of hurlers. Like Snell and Glasnow, Bubic is currently rehabbing an injury, though he doesn't appear to be nearly as close to coming back from the shelf and may not have enough time to get stretched back out for a starting role. According to MLB.com, Bubic increased his throwing distance off flat ground to 80 feet last week, so he could be a realistic option for the Dodgers at some point in the second half of August if they elect to bring him back as a reliever, per Jack Harris of the California Post. Bubic -- who is headed for free agency this winter -- submitted a 4.11 ERA, 1.23 WHIP and 51:26 K:BB across 50.1 innings in nine starts this season before being deactivated May 18 due to left shoulder discomfort and left elbow soreness.

The Marlins acquired Santana, infielder Brayden Taylor and right-hander Jacob Kisting from the Rays on Monday in exchange for catcher Liam Hicks, Joel Sherman of the New York Post reports.

The 21-year-old Santana has hit .316/.381/.400 with three home runs, 23 stolen bases and a 19:23 BB:K over 51 contests with High-A Bowling Green this season. Santana was a first-round pick in the 2023 First-Year Player Draft and has been used mainly at shortstop in pro ball, though he's also gotten some work at second base.

The Padres acquired Ray from the Giants on Monday in exchange for right-hander Miguel Mendez and shortstop Joniel Hernandez, Alex Pavlovic of NBC Sports Bay Area reports.

The addition of Ray provides a much-needed upgrade to the San Diego rotation, which has struggled throughout the season to get quality results from any of its starters beyond ace Michael King. Though the 3.08 ERA that Ray has posted over 122.2 innings in 2026 hasn't been supported by most of his underlying metrics (4.76 SIERA, 4.43 xERA, 9.8 K-BB%), the veteran southpaw has performed better overall since the beginning of June. Over his final 10 appearances (nine starts) with the Giants, Ray went 7-0 with a 1.65 ERA (3.53 xERA) and 1.17 WHIP. Per Pavlovic, the Giants and Padres are expected to split coverage of the approximately $8 million remaining on Ray's contract.

The Marlins acquired Taylor, shortstop Adrian Santana and right-hander Jacob Kisting from the Rays on Monday in exchange for catcher Liam Hicks, Joel Sherman of the New York Post reports.

Taylor is the most well-regarded of the three prospects headed to Miami. A first-round selection in the 2023 First-Year Player Draft, Taylor had a terrible 2025 campaign but has bounced back nicely in 2026, slashing .284/.384/.513 with 17 home runs, 20 stolen bases and a 51:87 BB:K over 88 games with Double-A Montgomery. The 24-year-old has mostly played third base in pro ball, but he has experience at second base and shortstop, as well.
