Forget about the Bronx Bombers, and meet the go-go Yankees. Early on, the station-to-station team that relied on the home run has been replaced by an aggressive group that puts pressure on the opposition.

Through 11 games, the Yankees lead the American League with 12 stolen bases after finishing 18th in baseball a year ago. This philosophical change began in the spring, when manager Joe Girardi told the two fastest Yankees, Brett Gardner and Jacoby Ellsbury, he wanted them to score 100 runs apiece.

“However you do it, I don’t care,” Girardi told them. “Just score 100 runs and whenever you can get an extra base, get an extra base.”

The trend continued in Saturday’s 3-2 win over the Cardinals at the Stadium, the Yankees’ sixth straight, with two more stolen bases, one apiece by Ellsbury and Chase Headley. The Yankees’ 12 steals have all come by Ellsbury, Headley and Gardner, who has a team-high five.

Ellsbury and Gardner are known quantities as base-stealers, despite not running as much in recent years, but Headley hasn’t reached double figures since 2012, when he equaled a career high with 17 stolen bases. The third baseman already has three after nabbing just eight last year and zero the season before.

“I used to run a lot, and I think the more that I’ve been here, Joe’s given me a little bit more freedom, given me some green lights to run when I have the opportunity and the numbers are right,” Headley said. “You’re not always going to hit the ball out of the ballpark, not always not going to stack four hits together. So you have to be able to do score runs in different ways, and this is a way we’re able to do that.”

Indeed, while the Yankees have hit 14 home runs in 11 games, they are fourth in the American League in runs scored with 51. They are being aggressive on the bases, forcing the issue, making up for the absence of catcher Gary Sanchez and shortstop Didi Gregorius, along with first baseman Greg Bird’s struggles at the plate.

“I’ve never wanted our club not to be aggressive on the bases,” Girardi said. “But sometimes, with the people you have, they’re not going to steal a lot of bases in a sense. Gardy has done a good job. Ells has done a good job. Headley has done a good job.

“So, I told our guys, whenever you can get an extra base, get an extra base, and that’s the bottom line. I’ve been saying that since Day 1, but sometimes your teams are more constructed to be more aggressive on the bases.”
