ATLANTA – Mets reliever Dellin Betances will undergo season-ending shoulder surgery after feeling discomfort during his rehab assignment, Luis Rojas announced – potentially putting in jeopardy a career that has been riddled with injury in recent years.

Betances had just one appearance with the Mets this year, a single inning against the Phillies, before landing on the 60-day injured list with a shoulder impingement. Betances previously missed significant time with the Yankees with a shoulder impingement in 2019 and then tore his Achilles. After joining the Mets on a one-year, $10.5 million in 2020, he was sidelined with a lat injury. He exercised his $6 million player option for this year, but didn’t have much to show for it.

"It’s always a good presence for a bullpen and from an experience standpoint, pitching in New York…it’s always an asset," Rojas said. "It’s unfortunate to hear about this and I feel for him. My prayers are with him, so we pray for a prompt recovery. We never want to see this happen but we pray Dellin’s career keeps moving forward."

Betances allowed eight earned runs over 3 2/3 inning in his rehab assignment before being shut down.

The Mets bullpen is already shorthanded, having lost Robert Gsellman to a torn right lat. The news is better for Jeurys Familia, who pitched a perfect inning in his rehab assignment Tuesday, and is expected back this weekend.
