Brad Keller’s injury in Philadelphia doesn’t just sting the Phillies. It also nudges Luke Weaver’s trade market higher.
The Phillies announced Thursday, ahead of their game against the Mets, that Keller is done for the rest of 2026 and could miss a significant chunk, if not all, of 2027 as well if surgery is required on his right elbow. Jeff Passan reported that Keller has a torn UCL and is expected to miss the rest of the season. Keller had signed a two-year, $22 million deal over the winter.
For Mets fans, the first reaction is obvious: what does that mean for Luke Weaver?
It doesn’t necessarily mean Philadelphia is suddenly the team to watch for a Weaver deal. But it does make the right-hander more valuable around the league. The Phillies’ bullpen just took a hit, and even if they aren’t the most obvious fit for Weaver, their need for help only got sharper.
That matters because the market for Weaver is already built on scarcity. Rising Apple’s Steve Parello recently identified three teams that should be willing to make the Mets a strong offer for him, and the Phillies were not among them. The reason is simple: their bullpen situation, even with Keller out, doesn’t line up as cleanly as teams that are hunting for a closer.
Still, if Philadelphia goes out and trades for another reliever, that changes the board for everyone else. Say the Phillies land someone like Adrian Morejon of the San Diego Padres. That’s one fewer high-leverage arm available to the rest of the market, and it pushes the price on Weaver even higher.
And the Mets don’t exactly have to move him. That gives them leverage.
At minimum, Weaver should cost a top 100 prospect, or something close to it, along with a major league-ready player. With so much uncertainty around Devin Williams as the closer, the Mets have every reason to wait for the best possible return. Weaver has shown he can handle multiple roles, and teams looking for stability in the eighth or ninth inning would be wise to pay up.
For the next two and a half months, Weaver is going to be one of the most closely watched names on the board. Trade rumors around him figure to run right up to the deadline.
Keller’s injury doesn’t bring the Mets and Phillies any closer to a deal, but it does reinforce one thing: Philadelphia needs a high-leverage right-hander, and whoever they add is one less option for everybody else. That only makes Weaver more expensive.

This Feels Like Exactly The Risky Mets Pitching Bet Stearns Loves
The Mets have already shown a willingness to keep turning over pitching bets, and late June brought another reminder when David Peterson was shipped to the Cubs for Cole Mathis. Around the league, Lance McCullers Jr. has become one of the more intriguing names to watch after Houston sent him and Colton Gordon to Milwaukee for Jadyn Fielder, a move that puts a once-promising arm in a new setting and gives clubs a fresh chance to evaluate what he has left.
For New York, the appeal is obvious enough even with the risk baked in. McCullers has spent the last two seasons fighting through major health issues and uneven results, and the kind of pitcher he becomes with the Brewers will matter more than his reputation ever could. If he can stay on the mound and show something closer to his old form, he could fit the sort of upside play the Mets have not been shy about exploring, especially with David Stearns having known him from their time together in Houston.

Mets Deadline Selloff Could Soon Cost Them A Trusted Bullpen Arm
As the deadline approaches, the Mets are widely expected to move into sell mode, and one of the more appealing pieces on the roster is a left-handed reliever who has quietly been one of their steadier bullpen arms this season. Brooks Raley has given New York the kind of late-inning reliability contenders tend to chase in July, which is why he has started to surface in conversations around clubs looking for help on the left side.
Boston has been one of the teams linked as a possible fit, especially with a need for another matchup lefty to pair behind Aroldis Chapman. But the Red Sox have also played their way into a murkier spot, and their recent surge has made it harder to tell whether they will push in for bullpen help or stay patient, leaving any potential deal hanging on how they read the next few days.

Phillies Are Eyeing A Mets Starter And Fans Wont Like It
The Phillies have surged since Don Mattingly took over as interim manager, and their push toward the NL East race has only sharpened the focus on the trade deadline. According to ESPNs Buster Olney, Philadelphia is prioritizing starting pitching, with the middle of the rotation emerging as the area it wants to upgrade as it tries to keep pace in a tight division battle.
For Mets fans, the more unsettling part is that one of the names floating into that discussion is a current New York starter who is still working back from injury. He is on the 60-day injured list and expected to return in August, which makes him an especially intriguing possibility for a contender looking to add help without waiting too long, and it adds another layer to a deadline market that could get complicated quickly.
