The moment Philadelphia Phillies reliever Brad Keller went down with a UCL tear, panic struck within the fanbase. An already shaky bullpen has now become pure uncertainty weeks out from the MLB trade deadline. After signing a two-year deal this past offseason, Keller was expected to be the setup man ahead of closer Jhoan Duran, but the injury will now take him out for most of his remaining Phillies tenure. The Phillies need a lot of help and do have an immediate team they could purge from before Aug. 3, but it could cost them extra to get it done.
The New York Mets just took two of three from the Phillies coming out of the break, but they remain strong sellers heading into the deadline. They could go on a fire sale, and that could include right-handed reliever Luke Weaver. The Phillies need to consider a big name on the market, and Weaver would be a strong replacement for Keller; according to MLB insider Bob Nightengale, such a match is a possibility. The Mets would have to wrestle with the idea of sending Weaver to Philadelphia but could balance it out with a heftier ask.
Phillies-Mets trade rumors would come with a potentially inflated price for key reliever
Weaver signed the same contract with the Mets as Keller did with the Phillies (two years, $22 million). In 38 games in 2026, Weaver has pitched to a 2.03 ERA, 0.83 WHIP, and 43 strikeouts in 40 innings pitched. He's been great during his time in Queens, along with his previous few seasons with the New York Yankees. He will cost a pretty penny to get him to Philadelphia, given the Mets' desire to gouge the Phils, but Dave Dombrowski should spare no expense here, given their growing void in the bullpen.
The Mets will be offloading a bunch of money at the deadline, but selling to a division rival won't be a given. The conversation might have to start with their top pitching prospect and recent Futures Game starter Gage Wood. It's a risk the Phillies have to at least entertain, given the market and the position they're already in with the carousel at the right field position. They want to maintain the playoff spot, and it will cost them to retain it.
The other big name on the market is San Diego Padres' closer Mason Miller. He's the ultimate prize if the Phillies wanted the best one-two punch in MLB. What the Padres had to give up to get Miller at the deadline last year in the first place does, however, make it less appealing or even feasible. The Phillies would be looking at cleaning house of the farm system to haul him in. Who only knows what Miller would cost now?
The Phillies should be cautious of Weaver's price tag. It would be another roadblock in their quest of assembling a competent relief corps. On the other side, taking Weaver away from a division rival and having that immediate success would also do wonders for an unsettled fan base in Philadelphia. It's a big splash for an already expensive roster, but that's where the Phillies are at right now with building a championship-caliber team.
