Teixeira, Unsure of Return, Is Heading to Tampa Yankees first baseman Mark Teixeira said he plans to travel to Tampa, Fla., on Monday to ramp up the rehabilitation efforts on his strained left calf, but he remains unsure when he might return to the lineup. Teixeira said Thursday he is hesitant to put any timetable on his return after what happened last time, when he rushed back and ultimately reinjured the calf diving for first base against the Baltimore Orioles on Sept. "It is what it is," Teixeira said. It's not like I can play through it. I tried. So we just have to be a little bit smarter about it. Teixeira said he has only been getting treatment and doing pool exercises since the game in Baltimore, but would take some swings in the batting cage Thursday. He hoped to do some work in the field later this weekend. In Tampa, Teixeira said he could play in an instructional league game at some point. Teixeira first strained the calf on Aug. 27 and did not play until 10 games later, against the Orioles. But in the ninth inning, hurrying to beat out a game-ending double-play ball, Teixeira dove into first. He has not played since, and he said the calf is still sore, swollen and tight. "Once that goes away, and they can see that I'm running full speed, making cuts, being able to do everything I need to do on a baseball field, then I'll be able to come back," he said.
