Earlier this season, Mickey Callaway mentioned that he wanted to try to manage the workload of righty Robert Gsellman as he progresses in his transition from the starting rotation to a full-time reliever.
However, the training gloves have very quickly been removed. Just a month an a half into the 2018 season, Gsellman has quickly become one of Mickey Callaway’s first and most reliable options in the shaky New York Mets bullpen.
Over the last 15 days, Callaway has leaned on the right-hander and it has mostly paid off. He has made six different appearances over 12.2 innings, and has thrown a total of 153 pitches. His last three outings have also all covered two or more innings, including his three scoreless innings in Sunday afternoon’s loss to the Phillies.
The heavy workload has Gsellman showing some signs of fatigue. The strikeout numbers have been down, and he has been giving up a ton of hits as of late. Over the 15-day span, Gsellman has only struck out five batters. He has allowed six runs on 13 hits, three of which were home runs to raise his ERA to a 3.16 mark.
With the back-end of the Mets rotation struggling, it is possible Callaway is trying to stretch out Gsellman in anticipation of a return to the rotation. Either way, it is certainly vital to Gsellman’s success that he receives some rest or a smaller workload the next few days/weeks.
Gsellman has otherwise been one of the most consistent performers in an up-and-down Mets bullpen. In total during the 2018 season, he has a record of 4-0 with 24 strikeouts, nine earned runs, a 3.16 ERA , and a 1.32 WHIP over 25.2 innings.
