ATLANTA -- New York Mets reliever Dellin Betances will have surgery on his right shoulder and miss the remainder of the year after pitching just once this season.

Betances gave up one run in one inning against the Philadelphia Phillies on April 7 and was placed on the 60-day injured list the next day with a right shoulder impingement.

Mets manager Luis Rojas said Wednesday that Betances "has been playing with some shoulder pain." Betances had a 19.24 ERA with two minor league teams in his rehabilitation assignments.

"He's always a good presence for your bullpen, and from an experience standpoint pitching in New York, it's always an asset," Rojas said. "It's unfortunate to hear about this."

The 33-year-old Betances was a four-time All-Star with the New York Yankees. He pitched only once in 2019 because of injuries, then signed a one-year, $10.5 million deal with the Mets that included a $6 million player option for 2021, which he exercised.

Betances was 0-1 with a 7.71 ERA in 15 games with the Mets in 2020.
