According to Adam Rubin of ESPN New York, lefthanded reliever Jack Leathersich may have to undergo Tommy John surgery. He will be evaluated by team doctors who will make a final determination.
Leathersich, 25, has not appeared in a game since June 29 when he threw 57 pitches during a relief outing with Triple-A Las Vegas a day after he was demoted from the big league team.
In 17 appearances this season for the Mets, Leathersich had a 2.31 ERA and 1.629 WHIP in 11.2 innings pitched with 14 strikeouts and seven walks.
