Hunter day to day after hurting right hamstring

DETROIT -- After exiting Monday night's game with what Brad Ausmus called a "knotted" hamstring, right fielder Torii Hunter is day to day, according to the Tigers manager.

Hunter blooped a single before sustaining the injury to his right hamstring while rounding first.

"We don't expect, at this point, that it'll be anything long term," Ausmus said. "We'll see how it is tomorrow. [Trainer Kevin Rand] was more optimistic than pessimistic."

The 38-year-old Hunter has had no trouble staying healthy the past few seasons. His last trip to the disabled list came in 2009 when he strained a muscle in his thigh.

In 59 games this season, Hunter is batting .264 with an on-base percentage of .289. He has 13 doubles and nine home runs.

J.D. Martinez, who knocked his second career grand slam in the ninth inning, replaced Hunter on the basepaths. The Tigers still fell to the Royals, 11-8.
