The Yankees formally introduced new outfielder Jacoby Ellsbury at Yankee Stadium Friday.
Ellsbury, a former member of the Red Sox, will wear number 22 in pinstripes.
The 30-year-old Ellsbury inked a seven-year, $153 million deal with the Yanks.
Ellsbury led the majors with 52 steals last season, despite breaking his foot late in the season.
He also posted a .298 average, nine homers and 53 RBIs in 2013.
"I'm excited for this opportunity, coming to a storied franchise, looking outside today, seeing the banners on the wall, seeing the great players that have played here," Ellsbury said. "Hopefully, when it's all said and done, we can hoist that trophy above our head."
"You are going to make my job a lot easier," said Yankees manager Joe Girardi. "You no longer are a thorn in my side. You are a flower in our clubhouse, and I'm happy to have you."
Ellsbury wore number 2 with the Red Sox, but that number is already taken by Derek Jeter.
