Martinez suffers hamstring tightness

Catcher pulls up lame on the basepaths in second inning

CLEVELAND -- Home openers, whether they're completed or not, have not been kind to Victor Martinez lately.

Martinez left Monday's game against the White Sox in the second inning with left hamstring tightness, suffered when he tried to advance from first base to second on a ball in the dirt. After the game, the Indians did not yet have the results of an MRI performed on the leg. Martinez is listed as day-to-day.

"It's something going on with his hamstring," manager Eric Wedge said. "I have not received a report, outside of the fact that they're taking a look at it."

Last year, Martinez left the original home opener against the Mariners when he strained his left quadriceps muscle while running to first. That game, called because of snow in the top of the fifth inning, didn't count, but Martinez's injury did. He ended up missing six games because of the quad problem.

This time around, Martinez hurt his hamstring while trying to get to second when one of Nick Masset's pitches was thrown in the dirt. Martinez pulled up lame before getting to the bag and was easily tagged out. Before the injury, he had two hits, a run scored and an RBI in two second-inning at-bats.

"We'll hope for the best and see what we find out," Wedge said.

Martinez was the key to the Indians' offense last season, batting .301 with 25 homers and 114 RBIs and ably filling the void left by Travis Hafner's struggles. He reported to Spring Training camp this year looking to be in better physical shape than ever.

Backup Kelly Shoppach replaced Martinez on Monday and went 1-for-2, scoring the go-ahead run in the eighth inning. If Martinez is down for a substantial amount of time, the Indians have Yamid Haad and Wyatt Toregas available at Triple-A Buffalo to back up Shoppach.
