BOSTON — The American League East battle ended Friday night. It was probably over before that. And, after Saturday, the time when the Yankees really had a shot felt like eons ago.Still, the Yankees are ignoring — at least publicly — that they’re best hope is to reach the AL Wild Card on Oct. 3.They’re not winning the division, especially not after a 4-1 loss to Boston at Fenway Park that dropped them 8 1/2 games back of the Red Sox in the East.Yankees trade with IndiansGiancarlo Stanton, who doubled twice Saturday, said the Yankees understand the hole they have dug but can’t let themselves think that way.”It’s obviously a thought,” Stanton said. “It’s reality. You’ve got to understand it. But it is. You’ve got to try to keep it simple. We lost (Saturday). We’ve got to win tomorrow. That’s it. We know what the deficit is. We know what’s at stake. We’ve got a game we’ve got to win tomorrow.”Greg Bird, who flew out with the bases loaded in the ninth to end it, refused to call it over.”There’s a lot of baseball left,” he said. “You can’t look at it like that. We’ve got to bounce back and get a win tomorrow. That’s really the main thing. But a lot of baseball left. These kinds of things can really bring guys together (and) closer, I think can be good for a team. We go through it now, we learn from it and we keep moving on.”This group, we’ve got some new guys, but we’ve been through it together,” Bird added.
