DETROIT -- Cubs catcher Geovany Soto was pulled from Tuesday's game after he tweaked his left thumb on a swing in the eighth inning but said the move was precautionary.

Soto struck out swinging to end the eighth inning, and Koyie Hill was inserted behind the plate for the final two innings of the Cubs' 5-4 loss to the Detroit Tigers.

"I've done it a hundred times," said Soto, who aggravated an old injury with his swing. "My thumb, I pulled it a little bit. It hurt a little but nothing major. Lou [Piniella] asked me if it hurt a little bit, and I said it bothered me. He took me out to try to protect me in that situation right there."

The Cubs had taken a 4-3 lead at that point on Micah Hoffpauir's two-run homer in the eighth. Soto was 0-for-3 in the game with a sacrifice fly and batting .222. He expected to be in the lineup for Wednesday's game.

"I could've kept going today," Soto said. "[Piniella] told me to give it a rest. I could've played, no problem."
