Teixeira dealing with ailing left hamstring

KANSAS CITY -- On Sunday, it was Brett Gardner and Jacoby Ellsbury nursing injuries. Mark Teixeira added his name to the list Monday, as the first baseman was not in the starting lineup for the makeup game against the Royals.

Teixeira, who was available to pinch-hit, suffered a minor injury to his left hamstring while running the bases Thursday or Friday. New York playing 13 straight games, including three games in three cities, factored into Yankees manager Joe Girardi giving Teixeira the break from the starting lineup.

"This is a brutal stretch of games, and we've got some guys banged up, so any opportunity to get some rest, we're going to try to take advantage of it," Teixeira said.

Gardner joined Teixeira on the bench, as the left fielder missed his second straight game with an injury to his right ankle.

"I'm encouraged with the way it feels today, hopefully I can do some things on it today and get back to full speed tomorrow," said Gardner. "I feel a lot better today than I did yesterday."

Gardner was absent from his team's 7-4 win over the White Sox on Sunday, one day after fouling a ball off his ankle.

"He's a huge part of our lineup, but guys have to step up," Girardi said. "Guys stepped up yesterday, and we need to do it again today."

Ellsbury returned to his spot atop the Yankees' order Monday.
