Detroit Tigers manager Jim Leyland had a sneaking suspicion something might be wrong with right-hander Al Alburquerque on Wednesday night.

So he and Tigers head athletic trainer Kevin Rand made a trip to the mound in the seventh inning to check on the 26-year-old.

Sure enough, Alburquerque's hip had tightened up.

"I was real suspicious when I saw him throwing to the last batter," Leyland said.

Alburquerque said he "felt something pinching me in the groin" on his right side, but didn't expect it to be a "serious" problem.

"I think I need to stretch more before I pitch in the game," he said. "It's nothing serious. I don't feel like it's anything serious."

Alburquerque said tightness developed after he threw his second pitch to Royals first baseman Eric Hosmer in the seventh. He eventually walked Hosmer and after his first pitch to Lorenzo Cain, a ball, Leyland took a visit to the mound.

"He saw something wrong with me -- like it wasn't normal," Alburquerque said. "But I said I was OK because I wanted to make it through my inning."
