According to Matthew Brownstein of MetsMinors.net, Mets pitching prospect Colin Holderman underwent Tommy John surgery and will not pitch in 2018. Holderman is currently on the Columbia Fireflies’ disabled list, along with fellow Tommy John patients Joel Huertas, Max Kuhns, and Thomas Szapucki.

Holderman, 22, was the Mets’ ninth-round pick in the 2016 June draft from Heartland Community College (IL). He made his professional debut that summer with the Kingsport Mets, where he worked 18.2 relief innings. To begin the 2017 season, the 6’7″ right-hander was promoted to the Fireflies and began the season with a six-inning, one-hit, no-walk, 11-strikeout performance against Hickory.

Holderman would end up making three more starts in April for Columbia but quickly succumbed to a labrum injury in his shoulder that took him out of game action until late July. He made three rehab appearances for the Brooklyn Cyclones and GCL Mets before returning to the Fireflies.

In seven total starts in Low-A last season, Holderman was 2-3 with a 4.94 ERA, striking out 25 and walking 11 in 31.0 innings.
