Gsellman gave up eight hits and three earned runs while striking out five during 6.2 innings of work on Thursday.
Gsellman missed a start due to a strained groin injury that caused him to spend a week on the disabled list after the mild incident occurred on May 13. Since then, he has made two starts for Double-A Binghamton, allowing three earned runs in each and picking up losses in both outings. Before the injury Gsellman held an impressive 2.21 ERA and 1.04 WHIP, and with a 42:13 strikeout to walk ratio this season, he has the ability to keep opposing hitters off the basepaths. The 22-year-old could earn the chance to compete at a higher level at some point this year if he can settle back in and continue to pitch well for his club.
