Athletics pitcher Drew Pomeranz is dealing slight tightness in his right hip that came up during warmups Tuesday, according to CSN California.
Pomeranz, who has posted a 2.00 ERA in three starts, has dealt with the issue in the past and said it doesn't normally last beyond a day.
"It never loosened up," Pomeranz said to MLB.com. "I thought it would and it didn't, so I was fighting myself, fighting my front side the whole day. Made it a little difficult to fill up the zone."
He went 2 2/3 innings Tuesday, allowing two runs on three hits.
