Jesse Hahn left the game tonight in the top of the third with an apparent injury.
Hahn showed no signs of anything being wrong on pitch before he came out. Unclear what happened.

Hahn has had multiple arm injuries before, so the drop in velocity is particularly alarming.
Hahn’s velocity noticeably down this inning by about 4-5 mph.

Hahn was replaced by Bobby Wahl.
Update
It is in fact an arm injury. No word on the severity, but arm injuries are bad.
