Phillies Bullpen Suffers Significant Blow with Brad Keller Injury

The Philadelphia Phillies’ bullpen has suffered another major setback with the announcement that right-handed reliever Brad Keller has a torn ulnar collateral ligament in his throwing elbow. This devastating injury means that Keller is likely to miss the remainder of the 2026 season and may potentially be out of action for a significant portion of the 2027 campaign as well.

Keller, who turns 31 soon, is in the first year of a two-year, $22 million contract he signed with the Phillies during the offseason. If his UCL injury eventually requires Tommy John surgery, it is possible that he may not pitch again under his current deal. This season, Keller has registered a 4.02 ERA (114 ERA+) with 32 strikeouts and 13 walks in 31 ⅓ innings in a setup role for the Phillies.

‘Pen Problems Plague the Phillies

The Phillies’ bullpen has been a weak spot for the team in 2026, despite strong numbers from All-Star close Jhoan Duran. As of the second half of the season, Philly relievers rank 21st in MLB in bullpen ERA (4.44) but a more encouraging eighth in bullpen FIP. However, three of the Phillies’ left-handed relievers – Tanner Banks, José Alvarado, and Kyle Backhus – have particularly struggled this season, each with an ERA above 5.80. They have combined to allow 58 earned runs in 77 1/3 innings (a collective 6.75 ERA).

Looking ahead to the near-term, Keller’s injury may add an item or two to the trade-deadline shopping list of lead executive Dave Dombrowski. While the Phillies have surged back into playoff position and into contention in the National League East under interim manager Don Mattingly, help is still needed. In particular, the Phillies could use an additional starting pitcher and a right-handed-hitting outfielder, and that’s in addition to bullpen help. A trade for a reliever was probably already on the front office’s radar, and now losing Keller may mean that they’ll be seeking out multiple relievers before the Aug. 3 deadline.

In theory, bullpen help isn’t hard to find leading up to the deadline, but this time around the low bar for contention may mean fewer sellers and more competition for the players that are on the trading block.

The Phillies have been struggling to find consistency in their bullpen, and the loss of Keller is a significant blow. With the trade deadline approaching, the team will need to act quickly to address their bullpen needs. The Phillies’ front office will be under pressure to make a move, and the team’s fans will be eagerly waiting to see what they have in store.
