Fister missed his last scheduled start with a groin injury sustained on Aug. 19. He threw a bullpen session on Tuesday and said he was feeling good.
Drew Smyly, who filled in for Fister on Saturday against the Angels, will pitch in a bullpen role starting Wednesday night against the Royals, according to manager Jim Leyland. When asked if that's a role Smyly will stay in the rest of the season, Leyland said that other circumstances could dictate that situation, particularly focusing on potential rainouts.
"That depends," Leyland said. "That depends on what happens with the weather, if you need another starter. You'll probably have some additional help here shortly [when rosters expand on Saturday] in the bullpen. Smyly will be in the bullpen, but if you needed a sixth starter for some reason, he would certainly, I think, be a candidate. But I can't predict what's going to happen with the weather."
