At the very least, Girardi said that he does not expect Teixeira to be available for any of this week's games against the Red Sox. Teixeira said that his calf doesn't feel as bad as the original injury, and he wasn't ready to consider the possibility of sitting out for the rest of the year.
"No, that would be worst worst-case scenario," Teixeira said. "Let's just hope the MRI says there's no new injuries or anything, and I'll just have to make sure that it's a little more healed the next time I come back."
Teixeira missed 10 games before returning to the lineup as the Yankees' first baseman on Saturday. He said that his calf felt tight all night, but he protected it by running at half-speed, including chugging to second base on a first-inning double.
That wasn't an option in the ninth inning, as Teixeira had to try to beat out a ground ball to second base with the potential tying run coming home from third base. Teixeira felt his calf grab as he raced down the line, sliding head-first into first base, where he was called out on the game-ending play.
"I thought I could play on it at 80 percent or whatever it was," Teixeira said. "I couldn't, so when I come back next time -- whether it's two days or a week, whatever it's going to be; I don't know how long it's going to be. I'll just make sure that it's better than 80 percent. Again, it's not going to be 100 percent, we know that. We just know that I have to make sure I can do a little more."
With Teixeira out of the lineup, Girardi said that he plans to continue playing Nick Swisher and Steve Pearce at first base. Pearce got the start on Sunday against Baltimore left-hander Zach Britton, but Girardi said the Yankees will have trouble replacing Teixeira.
"He's one of the guys that has been a huge part of our lineup, middle of the order, an RBI guy," Girardi said. "We talked about it yesterday, that until you got through a couple of days of playing, there would be concern."
