Manager Joe Girardi originally had Teixeira in his customary third spot in the order, acknowledging that it was a "wait-and-see" approach during pregame warmups. But after stretching with the team, Teixeira had difficulty even picking up a bat without pain, and so decided to wait at least one more day.
"It didn't feel good, so I figured it'd be best to give it a rest and hopefully it feels better tomorrow," Teixeira said after the Yankees' 2-1 win.
Teixeira suffered the injury on Friday night, diving for a ball down the first-base line in the fifth inning. He stayed in that game for a pair of at-bats, and he said the thumb didn't start bothering him until Saturday morning. He started Saturday's contest, only to exit after two innings.
He said on Sunday that it didn't feel that much better from Saturday.
"Maybe a little better, but not much," he said, while maintaining that it won't be a long-term issue. "I'm definitely day to day."
"Day to day, we'll see how he feels," Girardi said. "Hopefully it's not as sore tomorrow. If he needs another day, he needs another day."
With Teixeira out, Nick Swisher moved from right field to first base and up to the three-hole, with Austin Kearns taking over in right field.
Sunday marked the first game this season Teixeira missed due to injury. It's only the third time this year he wasn't in the starting lineup, with the other two coming because of the birth of his son earlier this month.
