MESA, Ariz. -- Dontrelle Willis left the Reds' split-squad game against the Cubs after one-third of an inning with an injury sustained on a run-scoring play.
Willis was backing up the plate on Bobby Scales' two-run single and may have tripped on a bat in the process. He limped back toward the pitcher's mound and was taken out of the game before facing another batter.
"He just had a little roll over with his ankle, and we wanted to get him out of there and make sure he doesn't get hurt," bench coach Chris Speier said after managing the split-squad game in Mesa. "It's not bad. They'll know more tomorrow."
Willis, battling to make the club as a non-roster invitee, walked two and gave up two hits, allowing two runs. He had been on a roll entering the game, having pitched scoreless two-inning outings his last two times on the hill.
Willis will undergo further evaluation at the team's complex in Goodyear, Ari.
