The A’s made a roster move prior to Saturday afternoon’s game against the White Sox, placing starting pitcher JT Ginn on the 15-day IL with right elbow inflammation, with left-hander Jacob Lopez taking his spot on the active roster:
The Athletics placed right-handed pitcher J.T. Ginn on the 15-day injured list retroactive to April 25 with right elbow inflammation and recalled left-handed pitcher Jacob Lopez from Triple-A Las Vegas.

This comes as a surprise as there was no indication that Ginn wasn’t fully healthy.
