Athletics' Zack Gelof: Likely headed for IL

Gelof was diagnosed with a left oblique strain Wednesday, Martin Gallegos of MLB.com reports.

Gelof's injury was initially described as "left abdominal soreness" and caused him to be scratched from Oakland's lineup prior to Wednesday's game. However, his injury now appears to be more severe than initially thought, and it will likely cause him to land on the injured list. The A's haven't specified how long the 24-year-old may be out for, but Abraham Toro, who filled in for Gelof on Wednesday, will likely see consistent reps at second base in his absence.
