"It's the first time Kevin has ever had any symptoms like that," Showalter said. "I'm hoping that it was simple tendinitis. Obviously, it wasn't hurting him pitching physically. Once he got loose, he was fine. Until we get through tomorrow, I am going to be very cautious with him about what the future holds."
Gausman, 24, has appeared in eight games (12 innings) out of the bullpen this season. He is 1-0 with a 4.50 ERA with 13 strikeouts and five walks.
If Gausman is cleared physically, he could begin a rehab assignment.
