2025 MLB Trade Deadline: Key Deals, Rumors & Statistical Insights

The 2025 MLB Trade Deadline is approaching fast, with teams making bold moves and strategizing for a postseason push. As of July 31 at 6 p.m. ET, all eyes are on front offices as they navigate a competitive market to address roster needs—whether it’s shoring up rotations, adding power bats, or acquiring high-leverage relievers. Below, we break down the most notable trades, emerging rumors, and the statistical context behind the decisions shaping this year’s deadline.

Yankees Address Hot Corner, Eye More Pitching

The New York Yankees made one of the first major splashes by acquiring third baseman Ryan McMahon from the Rockies in exchange for top pitching prospects Griffin Herring (No. 8) and Josh Grosz (No. 21). McMahon, a left-handed bat, has already slugged 16 home runs this season and has eclipsed the 20-homer mark every year since 2021. His manageable contract ($16 million in 2026 and 2027) gives New York cost certainty, while previous target Eugenio Suárez (36 HR, .918 OPS, MLB-leading 86 RBI) remains a free agent after this season. The Yankees’ infield defense and depth improve significantly, though rumors persist they are still pursuing rotation upgrades, including Pirates starter Mitch Keller (3.72 ERA, under club control through 2028).

Mets Bolster Bullpen, Seek More Outfield Help

The Mets addressed a glaring bullpen need by trading for left-handed reliever Gregory Soto from the Orioles, giving up right-handed prospects Wellington Aracena (No. 19) and Cameron Foster. Soto, a two-time All-Star, brings a 3.96 ERA and 44 strikeouts in 36.1 innings this season. With Brooks Raley returning from injury, the Mets now have a formidable pair of lefties in their bullpen but are rumored to be exploring moves for a slugging center fielder to boost their lineup.

Mariners and D-backs: Bat Swaps and Selling Mode

The Mariners filled a key hole at first base by acquiring Josh Naylor from Arizona, sending back Brandyn Garcia (No. 13 SEA prospect) and Ashton Izzi (No. 16). Naylor, who posted an .807 OPS and 11 homers in his first 93 games with Arizona, adds much-needed left-handed power. For the D-backs, the move signals a potential shift to seller mode. Arizona is reportedly shopping several key players, including Eugenio Suárez, Zac Gallen, and Merrill Kelly—all impending free agents. Suárez in particular is drawing heavy interest from contenders like the Yankees, Mariners, Cubs, and Astros.

Padres, Red Sox, and the Outfield Market

San Diego continues to be one of the most aggressive teams, proposing a blockbuster deal to Boston for outfielder Jarren Duran that would have included starter Dylan Cease and top prospect Ethan Salas. While the Red Sox declined, both clubs remain active in the market. The Padres are also linked to Marlins ace Sandy Alcantara (2022 NL Cy Young winner), while the Red Sox are exploring upgrades to their rotation—possibly targeting Kansas City’s Kris Bubic, a 2025 All-Star with club control through 2026.

Brewers, Phillies, and Bullpen Arms

The Brewers are rumored to be targeting Eugenio Suárez to solve their lackluster third base production (26th in MLB in OPS at the position). Meanwhile, the Phillies are in the market for high-leverage relievers and have been linked to Minnesota’s Griffin Jax (K/9 over 14, three years of club control) and Guardians closer Emmanuel Clase. Philadelphia may need to part with top prospects like Justin Crawford (.329 AVG, .400+ OBP) and Keaton Anthony to get a deal done.

Other Notable Moves and Rumors

Braves: Acquired RHP Dane Dunning from the Rangers to bolster a depleted rotation.
Royals: Reacquired 2B Adam Frazier from the Pirates, signaling buyer intent despite a sub-.500 record.
Rays: Traded for Orioles reliever Bryan Baker, giving up a Competitive Balance Round A pick for 2025 to strengthen their bullpen.
Giants: Pulled off a blockbuster by landing DH Rafael Devers from the Red Sox in exchange for four prospects, including top lefty Kyle Harrison.

Statistical Context & Deadline Outlook

With several division races tight and wild card berths up for grabs, teams are leveraging statistical analysis and prospect capital more than ever. The deadline is defined by a mix of high-powered bats (Suárez, McMahon, Naylor), elite relievers (Soto, Jax, Clase), and controllable starters (Keller, Bubic, Alcantara). Clubs like the Yankees and Mariners are making aggressive moves to shore up weaknesses, while teams like the D-backs and White Sox are looking to maximize return on their expiring contracts and high-upside players. Expect more movement and surprises as July 31 approaches, with playoff hopes hanging in the balance for many contenders.
