Yankees Lose Brad Keller As Rivals Snag Another Top Bullpen Arm

As the bullpen market heats up, the Yankees risk falling behind after missing out on another ideal fit in Brad Keller.

Yankees Miss on Brad Keller as Phillies Land Premier Reliever - and the Bullpen Clock Is Ticking

The Yankees just watched another key bullpen target slip through their fingers - and this one stings.

Brad Keller, one of the breakout arms of 2025, is heading to the Phillies on a two-year, $22 million deal. For a Yankees team in desperate need of bullpen reinforcements, especially ones who can induce ground balls and miss bats, Keller wasn’t just a good fit - he was arguably the perfect one.

Instead, he’s off to Philadelphia, and the Yankees are left staring at a thinning market with their fiercest rivals scooping up the arms they should’ve been locking down.

Keller Was Built for the Bronx

Let’s not sugarcoat it: Keller was a tailor-made addition for this Yankees bullpen. After reinventing himself with the Cubs last season, the 30-year-old right-hander delivered a 2.07 ERA across 68 appearances, striking out 75 in just under 70 innings.

But the numbers go deeper than that - this wasn’t a flash-in-the-pan season. Keller was dominant, efficient, and reliable in high-leverage spots for a playoff-caliber team.

He posted a 0.96 WHIP, a mark that screams late-inning trust. He didn’t just keep runners off base - he suffocated lineups. His 56.6% ground ball rate made him one of the best in the league at keeping the ball out of the air, and in Yankee Stadium - where fly balls can become souvenirs in a hurry - that kind of profile is gold.

Metrics That Should’ve Made This a No-Brainer

Keller’s 2025 advanced metrics weren’t just good - they were elite. We’re talking 99th percentile in hard-hit rate, 95th percentile in ground ball percentage, and top-10 percentile marks in both expected ERA (2.82) and expected batting average (.200). That’s not just a reliever who can get outs - that’s a guy who can shut the door and keep the ball in the yard.

His fastball averaged 97.1 mph and sat in the 88th percentile for velocity, but it wasn’t just the heat that made him effective. He mixed in sliders, sweepers, and sinkers with precision, keeping hitters guessing and off balance. That kind of arsenal plays in October - and now it plays in Philadelphia.

Meanwhile, Across Town…

To make matters worse, the Mets continue to build their own bullpen Frankenstein, adding both Devin Williams and Luke Weaver - two more arms with Yankees connections - as they load up for a run of their own. The Yankees, meanwhile, are watching the market shrink by the hour.

It’s not just that Keller is gone - it’s that the options behind him are dwindling fast.

All Eyes Now on Bednar and Doval

With Keller off the table, the pressure now shifts to David Bednar and Camilo Doval. Both are All-Star caliber relievers, but asking them to shoulder the bulk of the high-leverage innings without a deeper supporting cast is a risky bet. October baseball demands depth - not just talent - and the Yankees are flirting with danger by standing pat.

Unless Brian Cashman and the front office are ready to open the checkbook for another top-tier arm, this bullpen could enter 2026 looking strong on paper but thin where it matters most: durability and depth over a 162-game grind and a potential postseason run.

The Clock Is Ticking

The Yankees still have time, but not much. The market is moving fast, and the teams that are serious about October aren’t waiting around.

The Phillies just added a proven weapon to the back end of their bullpen. The Mets are stacking arms like they’re building a playoff fortress.

The Yankees? They’re watching the board shrink, hoping their internal options can hold up.

Hope isn’t a strategy - not when the AL East is this competitive and the postseason margin for error is razor-thin. If the Yankees want to avoid déjà vu come October, they’ll need to act - and fast.
