The Phillies moved Keller (elbow) to the 60-day injured list Friday.
Keller suffered a brutal blow July 16, tearing his UCL just eight days after returning from the injured list with a forearm injury. The 30-year-old will now officially miss the rest of the 2026 season and potentially the 2027 season if he elects to get surgery to repair his UCL. The Phillies selected Payton Henry's contract from Triple-A Lehigh Valley to take over Keller's spot on the 40-man roster.
