But he felt something in that intercostal area, and Gausman said the treatment he's been getting has helped.
"I think it was more of a kind of a cramp, just a little bit of a tweak, but [I] feel fine a couple days later," Gausman said before Saturday's game against the D-backs. "They wanted to get some treatment on it and so after a couple days' treatment, it feels ready to go. I feel fine, like nothing even happened."
Showalter said he's hopeful that if everything falls into place, then Gausman would start Tuesday with Chris Tillman going Wednesday. No starter has been picked yet for Thursday.
