Kelley, who has had Tommy John surgery twice, said that his right elbow was fine and that the issue was a nerve problem in his fingers.
"I got ready quick and it's cool out there," Kelley said. "I threw that slider to Turner. I felt some numbness going down my hand. It took a second to try to get some blood flowing to it. When I threw the next pitch to Gonzalez, I didn't have any feeling in my fingers. It was tough to pitch."
After the game, Kelley told manager Dusty Baker that he was getting some feeling back in his fingers.
Kelley plans to talk to the team trainers and doctors.
"Hopefully, it's just a nerve thing," Kelley said.
