Reds pitcher Aroldis Chapman left an appearance on Monday early with a stiff lower back.
Chapman has been bothered by the stiffness for several days.
"I'm not hurt," Chapman said through a translator. "I had a little stiffness in my lower back. It has been bothering me for a couple days. I was able to work through it in the first inning, but it didn't get loose in the second inning."
