Mora expects to miss at least a week

Third baseman left Friday's game with strained left hamstring

ST. PETERSBURG -- Melvin Mora may not know the extent of his injury, but he does know he won't play anytime soon. Baltimore's third baseman, who strained his left hamstring while trying to beat out a ground ball in Friday's game, said Saturday that he's never experienced an injury like this and that he'll probably be out for at least a week.

"You have to heal and let it heal. I don't want to blow it up, but it depends on how I feel this week," said Mora, who has batted .393 since the All-Star break. "I was trying to do that last step. I was thinking I could beat it. It beat me."

The Orioles are pessimistic about his chances to return during the current road trip, and they made a personnel move to cover themselves on Saturday. Baltimore recalled infielder Oscar Salazar from Triple-A Norfolk and optioned starting pitcher Radhames Liz to make room. Manager Dave Trembley declined to say how he expects to fill in for Mora.

Trembley put Aubrey Huff at third base on Saturday and would only say that Salazar is "on the roster."

"I would think the best-case scenario for Melvin would be to be ready to play when we get off this road trip," Trembley said. "That's kind of how I see it. If he can play before that, I think it's a bonus. From how he feels today, it's improved. But I think it would probably be doubtful for him to play in Boston. He might be limited, he might be able to pinch-hit. With a day off Thursday, I think it's more realistic for him to be able to play after the day off on Thursday."

Mora, who leads the Orioles with 97 RBIs and is second in home runs (23), said he feels the injury most when he bends down. He hasn't tried to run yet, and said that he's not particularly concerned with his offensive statistics.

"I just want it to heal. If I don't make it to 100 [RBIs], I don't make it. I need to get treatment and see what happens," he said of the ailment. "I've never had that thing. I've just had a little cramp or something, but I've never had a pull."
