Showalter said Gonzalez would be available today in relief of Gausman, but Gonzalez also gives the club options in case right-handers Chris Tillman and Bud Norris cannot make their next starts.
Tillman, who walked five batters in five innings and allowed three runs and four hits in Sunday's 5-2 loss to the Houston Astros, threw a bullpen session Tuesday, but Showalter said he has “a little groin tenderness.
“I think that's going to manage well,” Showalter said. “But I want to make sure we're covered for him and Bud, depending on if the league decides to do something there [with a suspension], that we're covered pitching-wise there.”
Showalter said he hadn't heard any indication from Major League Baseball that Norris could face additional discipline from his eighth-inning ejection for hitting the Tigers' Torii Hunter on Monday night.
Gonzalez said he expects to return to the rotation, though he doesn't know when.
“It might be Friday, Saturday, Sunday,” Gonzalez said. “It depends on how the other guys are feeling.”
Bundy throws to live hitters in Sarasota
Orioles pitching prospect Dylan Bundy, who underwent Tommy John surgery in June to repair the injured ulnar collateral ligament in his right elbow, took another step in his rehabilitation Tuesday in Sarasota, Fla., when he faced live batters for the first time.
Showalter said it was a hybrid simulated game and live batting practice session, and the right-hander threw 20 pitches. Bundy, 21, reached 93 mph in the session, according to Showalter.
“Everything went real well, threw all his pitches,” Showalter said.
