Phillips exited in the fifth inning of a 4-3 Reds win Sunday as a precaution. Two innings earlier, he had slipped on loose dirt while rounding second base.
"I feel all right," Phillips said Monday. "If I feel it again taking ground balls or something, I'd probably say something about it. I think it was the wet conditions yesterday. They wanted to be safe with the postseason coming up."
In Monday's 4-2 loss, Phillips slipped again, in the third, and was again removed for precautionary reasons in the eighth.
"I felt like I could play the whole game," he said after Monday's loss. "It's just something I felt at the time. There's something about that turn going to the left. I'm OK. It's something I feel every once in a while. I told everybody I'm good and they have nothing to worry about. I will be ready to perform."
