CHICAGO -- Tigers first baseman Carlos Guillen was out of Saturday's lineup and is listed as day-to-day with a mild strain of his right hamstring.

Guillen suffered the injury in the ninth inning of Friday's 5-2 win over the White Sox, when he was running out a ground ball. He said he felt a little pull as he sped into first base to avoid a double play.

"It's pretty tight and sore," Guillen said Saturday morning.

After the game, Guillen said his hamstring was feeling better, but he did not expect to return for Sunday's series finale.

Guillen was out of the starting lineup for the first time this season. He's had one of the more productive bats for a Tigers offense that struggled for the first week and a half or so before producing 18 runs over a three-game stretch. Without Guillen, the Tigers didn't record a hit against White Sox starter Gavin Floyd for 7 1/3 innings in a 7-0 loss.

Guillen scored three times in Wednesday's 7-2 win at Boston, including once on a solo homer, and added a run in Friday's victory. He's batting .314 (11-for-35) with four doubles, two home runs, nine walks, eight runs scored and two RBIs.

To take Guillen's place, Detroit manager Jim Leyland moved starting third baseman Miguel Cabrera to first base and center fielder Brandon Inge to third while inserting hot-hitting rookie Clete Thomas in center. It marked Cabrera's first start at first in the Major Leagues.

The Cabrera shift, Leyland emphasized, was a preventative move to avoid worsening his sore left quadriceps.

"We are not moving Cabrera," Leyland said.
