Detroit manager Brad Ausmus said he held Davis out of Thursday's series finale with the Oakland Athletics because of the shoulder soreness.
"I didn't want to throw him back in there the next day," Ausmus said. "He's still a little sore. I can't say, if he didn't hurt his shoulder, he would have been out of the lineup. He's not in the lineup because of the shoulder."
Outfielder Torii Hunter, who hit solo home runs on Tuesday and Wednesday, was also out of the starting lineup, but for a different reason.
"I give Torii a day off because he's old, and you can tell him I said that," Ausmus said, smiling. "I played when I was his age. We need Torii for the long haul."
Left-handed-hitter Don Kelly took Hunter's place in the lineup.
