Lynch exited Thursday's start against the Athletics due to left calf tightness, Alec Lewis of The Athletic reports.

EDGE Analysis

Lynch appeared to tweak his calf on a pitch in the top of the third inning Thursday and was immediately removed from the contest. It's not yet clear whether the issue will force him to miss additional time. If he's able to make his next turn through the rotation, the southpaw tentatively lines up to start Tuesday against Cleveland.
