The Mets transferred left-handed reliever Danny Young to he 60-man injured list on Sunday morning, and the 30-year-old is reportedly set to undergo Tommy John surgery.
Will Sammon of The Athletic was the first to report.
Young, like A.J. Minter, has been a valuable lefty reliever for the Mets this season, pitching to a 4.32 ERA in 8.1 innings. Young also appeared in 42 games last season for New York, posting a 4.54 ERA.
Dealing with a forearm issue for a few weeks, per Carlos Mendoza, Young had not pitched in a game since April 27.
