"I'm feeling pretty good," Cain said. "I've got to go out there and make adjustments as quick as possible. I didn't get a chance to rehab, but at the same time I've got to go out there and get it done because we're in a playoff run here. I've got to do what I can to help this team."
Entering Sunday's game, Cain was batting .259 with 26 extra-base hits and 43 RBIs. He's also been a force on defense with a career-high seven outfield assists this season.
"He really improves our defense when he's out there," manager Ned Yost said. "With him, [Jarrod] Dyson and Alex Gordon in the outfield, it's as good an outfield defensive alignment as you can ask for, in my opinion. Once he gets hot, he can really drive the ball. I thought he had some good swings. We had to start working him back in there sooner or later, so we decided sooner."
