Mariners' George Kirby: Battling shoulder fatigue

Mariners general manager Jerry Dipoto said Monday that Kirby hasn't pitched at High-A Everett since July 10 due to right shoulder fatigue, Ryan Divish of The Seattle Times reports.

Dipoto noted that Kirby isn't dealing with any structural issues with the shoulder, and the Mariners remain optimistic that he'll slot back into the Everett rotation in a week or two. The 23-year-old right-hander posted a 2.56 ERA, 1.05 WHIP and 50:8 K:BB across 38.2 innings over his first eight starts with Everett before the shoulder issue surfaced.
