Mets' Robert Gsellman: Will undergo surgery Wednesday

Gsellman will undergo arthroscopic surgery Wednesday to repair a partially torn labrum in his left shoulder, Adam Rubin of ESPN.com reports.

Analysis:

The injury did not prevent Gsellman from pitching in 2016 because the damage was to his non-throwing shoulder, but it did prevent him from taking swings at the plate, and the decision was ultimately made to send him under the knife so he does not enter next season with any limitations. Gsellman will need at least three weeks to recover from Wednesday's procedure, but he is expected to be back at 100 percent when spring training begins.
