The Philadelphia Phillies got rolling just in time. After a brutal April that had fans calling for heads to roll, the firing of Rob Thomson and promotion of Don Mattingly turned things around. The Phillies are back in the NL East race and looking like a real threat. But the bullpen just took a hit they can’t ignore.
Brad Keller is out with a UCL injury. That’s a tough loss for a team that needs late-inning stability. The Phillies are going to be buyers at the trade deadline, and they don’t have much time to figure out who they’re targeting.
The New York Mets are having the opposite kind of season. They’re sellers. And they have exactly what Philly needs.
Luke Weaver Looks Like the Right Fit
Luke Weaver has quietly put together one of the better reliever seasons in baseball. He went into the All-Star Break with 25 straight appearances without giving up an earned run. Yeah, Trea Turner took him deep on Thursday, but that shouldn’t scare anyone off.
Weaver revived his career with the Yankees in 2024, working as their closer during the World Series run. He had a rough 2025 and the Yankees let him walk. The Mets scooped him up on a two-year deal and now they have a trade chip they can flip for prospects.
Weaver would slide right into the role Keller was filling. Jhoan Duran is the closer, no question, but Weaver has ninth-inning experience if something happens. It would cost the Phillies a lot to get him. But if they want to hang with the Braves and Dodgers in October, they need to pay up.
Still, one arm isn’t enough for what this bullpen needs.
The Phillies Need Left-Handed Help Too
Tim Mayza and Jose Alvarado are the top lefty options right now. In the NL playoffs, they’ll face Shohei Ohtani, Freddie Freeman, Matt Olson, Christian Yelich. That’s a murderer’s row of left-handed hitters. You need more than two guys you trust.
The Mets actually have two lefty relievers who could help: AJ Minter and Brooks Raley. Dave Dombrowski could solve two problems in one trade. It sounds unlikely because the Mets and Phillies hate each other. Deep-seated division rivals rarely make deals, especially when one team thinks it’s a contender. But this Mets season has been such a disaster that they have to prioritize the best return over old grudges.

The Phillies gave up premium prospect capital for Duran last year and got bounced early. That didn’t work, but the logic was sound. They need to do it again. The Mets have a young outfield built around Juan Soto, so they need pitching and infield bats. Right-handed pitcher Moises Chace, Philly’s No. 8 prospect, makes sense as a centerpiece. He’s 23 and close to MLB-ready.
The trade deadline is August 3. With the Wild Card races as tight as they are, there aren’t many clear sellers. The Mets are one of the few. And the Phillies have the need and the prospects to get something done. It just comes down to whether two division rivals can see past the history and make a deal that helps both sides.
