Yankees manager Joe Girardi was relieved to learn that Teixeira's issue was not related to the oblique, which could have necessitated a stint on the disabled list. Teixeira leads the Yankees in homers (11) and RBIs (31).
"He's a big home run threat. He's an RBI guy," Girardi said. "He's huge in the middle of the order between some lefties; a switch-hitter that really does damage against left-handers if they want to bring in a lefty to face some of our guys."
Teixeira likened the issue more to a spasm below his left shoulder.
"We're not sure exactly what it is," Girardi said. "I think we all wake up with some aches and pains some days, and the next day, you feel a lot better. It's hard to say what exactly it was."
