Manager Joe Girardi revealed before Wednesday's 6-4 Yankees win over the Twins in Game 1 of the American League Division Series that Teixeira had the shot administered after his team's Sept. 17-19 series in Baltimore. From that point through the end of the regular season, Teixeira slugged three homers and knocked three doubles, after owning only two extra-base hits -- and no homers.
Teixeira continued his revival in Game 1 of the ALDS, hitting a tiebreaking homer that put the Yankees up for good.
"It encouraged me that after he got the shot, he seemed to be swinging the bat a lot better," Girardi said. "His hand was feeling better. The [dangerous] part for him is when he dives after a ground ball. His instincts are always going to tell him to dive; he puts that hand down and it hits, and it bothers him when he dives. You hope that it doesn't happen a whole lot here."
Teixeira bruised his right thumb while diving for a ground ball on Aug. 27 in Chicago. The switch-hitter has also been fighting a fractured pinkie toe on his right foot, having batted just .220 (24-for-109) with three homers and 13 RBIs in September and October before Game 1.
