The 2015 season has come to an end for New York Mets‘ pitcher Jack Leathersich. The left hander underwent successful Tommy John surgery on Thursday in Manhattan. Mets team doctor David Altchek performed the procedure.

According to ESPN, it was unclear if the pitcher would require the ligament-replacement procedure. The initial hope was that a less serious procedure could be performed to address a bone spur and nerve issue, but that wasn’t the case.

Leathersich went 0-1 with a 2.31 ERA, 1.629 WHIP and 14 strikeouts over 11.2 innings in 17 relief appearances for the Mets at the major league level this season. While with the Mets Triple-A affiliate Las Vegas 51s, the lefty posted a 5.40 ERA with 22 strikeouts over 13.1 innings in 13 games.

The Beverly, Massachusetts native was sent to the minors prior to the procedure, therefor he will not accumulate major league service time while he heals and rehabs the injury. This is unless New York opts to put Leathersich on the 60-day disabled list to free up a spot on the 40-man roster.

Leathersich made his major league debut on Wednesday, April 29 after spending the past five seasons in the Mets’ minor league system. The 24-year-old entered Wednesday night’s game against the Miami Marlins with two outs in the eighth inning. After bringing the count to 1-2 on four pitches, Leathersich gave up a pinch-hit single to Justin Bour to right fielder Curtis Granderson. However, Bour was tossed out at second base when he over-slid the bag trying to stretch the hit into a double.

The former UMass Lowell River Hawk standout pitcher remains the highest-ever drafted player out of the University. Leathersich was taken in the 5th Round (162nd overall) by the Mets during the 2011 MLB June Amateur Draft. He was the first River Hawk taken in the MLB Draft in seven years and the first player out of UMass Lowell drafted in the first 10-rounds since 2002.
