Gsellman was promoted to Triple-A Las Vegas on Wednesday, Adam Rubin of ESPN.com reports.

EDGE Analysis

The 22-year-old had a 2.71 ERA and 1.09 WHIP through 11 starts at the Double-A level and will now continue his progression through the minor leagues with Triple-A Las Vegas.

Gsellman gave up eight hits and three earned runs while striking out five during 6.2 innings of work on Thursday.

EDGE Analysis

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.

Gsellman was placed on the disabled list Friday, Adam Rubin of ESPN New York reports.

EDGE Analysis

Gsellman had been pitching very well as a member of the Double-A rotation, sporting a 2.21 ERA and 1.04 WHIP. It's unclear what's ailing the 22-year-old, but his timetable for return should become clearer once that information is revealed.
