Broxton, who said he felt fine throughout warmups, opened the eighth by allowing a solo home run to Gerardo Parra. After the first pitch to Wil Nieves, Broxton said he knew something was wrong when it felt like a knife went through the belly of his forearm, but he tried to battle through the pain. He then walked Nieves on three more pitches before coming out of the game.
"Just that one pitch, it felt like it pulled apart," Broxton said. "Next pitch -- the cutter -- it hurt even worse. After that, I was just trying to get through it, try not to embarrass yourself or get somebody hurt. At that point, all your thinking about is trying to get out of it with no pain. You can't pitch up there like that."
Closer Aroldis Chapman replaced Broxton and picked up the two-inning save. Although he had to look out for his own health, Broxton appeared most disappointed after the game that he put more pressure on Chapman and the rest of the bullpen. Manager Dusty Baker, however, was more concerned about the 29-year-old right-hander, who just returned to the Reds on Aug. 7.
"That was really disheartening to have to go and get Broxton," Baker said. "I went out there. [Pitching coach] Bryan Price said, 'Aw man, he's done.'"
Baker and the Reds will know more after Broxton sees a doctor on Friday, but the Cincinnati skipper was not optimistic following Wednesday night's game.
"He told me it's not something that's going to be OK in a couple of days," Baker said. "Plus, we can't afford to be short in the bullpen. I don't know what we're going to do tomorrow."
