Suarez sits with back tightness

DETROIT -- One-half of the left side of the Tigers' infield was back in commission Wednesday night.

Nick Castellanos, who sustained a contusion on his right index finger during batting practice Tuesday, was in the lineup for the second game of the series against the White Sox.

But Eugenio Suarez, who was forced out of Tuesday night's game by lower back tightness, was out of the lineup Wednesday.

"I feel better," the rookie shortstop said. "But my lower back is hurt. Not too much like yesterday, but right now I feel like a little pinch. When I bend down to take ground balls, it hurts."

Suarez said that he only feels the tightness while fielding grounders, and he hopes to return to the lineup Thursday.

Manager Brad Ausmus said he isn't "overly alarmed" by Suarez's back tightness. Andrew Romine filled in at shortstop Wednesday night.
