GOODYEAR, Ariz. -- Shortstop Hiro Nakajima left the Oakland Athletics game Tuesday with a strained left hamstring. After reaching base on a single in the 10th inning, Nakajima grabbed his left hamstring while advancing to second base on a sacrifice bunt.
With his left hand on the back of his left leg, Nakajima motioned toward the dugout as A's manager Bob Melvin, trainer Nick Paparesta and interpreter Hiroo Nishi rushed to his aid. He left the field under his own power with a slight limp.
Nakajima, 30, didn't stop to address the media as he boarded the team bus after the game. He mentioned in passing to the Japanese media that he felt a cramp in his leg, and joked that he'd be fine in time for Wednesday's game.
The hamstring hadn't been bothering him previously. The timing of the injury is especially difficult for Nakajima, who broke an eight-game 0-for-20 slump with his 10th inning hit.
"It's too bad," Melvin said. "Hopefully it's nothing significant and he'll be back out playing in a few days. You don't know with hamstrings. They can be difficult injuries."
Nakajima's injury comes on the heels of an injury to infielder Adam Rosales, who was placed on the 15-day disabled list on Tuesday.

If both Rosales and Nakajima start the season on the DL, then the A's infield roster battle essentially solves itself. The team would then have room for Scott Sizemore, Eric Sogard and Nate Freiman.
"We know we have some depth and we have guys playing well," Melvin said.
