Athletics left-hander Drew Pomeranz played catch on Tuesday after leaving Monday's start with tightness in his left shoulder. Pomeranz said he felt some "normal soreness" which he expected, according to the San Francisco Chronicle.
The team has not confirmed if Pomeranz will be forced to miss his next start, but it does not appear this injury as all too serious at this time.
"We're going to have him looked at," manager Bob Melvin said to Bay Area News Group. "We'll probably make a decision on where we are tomorrow. Obviously there’s a chance he will go on the DL.
"This is something that’s been going on for a while, and we don't want it to continue to go on, but we haven’t made a definitive decision."
