Ichiro remains hot, hitting .327 (71-for-217) as a Yankee after a .385 (35-for-91) September, but Girardi said Swisher's career numbers against Boston starter Jon Lester prompted the move. Swisher entered the evening hitting .318 (14-for-44) in his career against the left-hander and is 4-for-8 against him this year.
Ichiro's numbers are similar -- .294 (10-for-34) in his career and 4-for-9 this year -- but Swisher has a larger sample size, and Girardi likes his familiarity with Lester.
Ichiro moved to the nine-hole, where he will hit behind Eduardo Nunez, who was at designated hitter and 9-for-35 since returning to the Yankees as a September callup, but the only middle infielder available to Girardi off the bench.
"He's been swinging the bat pretty good," Girardi said. "The one thing it does is it's my backup infielder and that's something I have to worry about, but I like the way the kid's swinging the bat."
