Stephen Drew left the Yankees Wednesday for Pittsburgh to see a concussion specialist, Joe Girardi said before the game. "That was the gentleman he saw before, when he had his concussion years ago. I'm assuming he'll be back tomorrow," the manager said.

Drew appears unlikely to play again soon, if at all this season. He has been experiencing dizziness, which had at first been connected to an illness but has since been associated with the second baseman having been hit in the face with a ball while fielding. He experienced a concussion in spring training of 2013, having been hit in the head by a pitch. At the time, he left the Red Sox to be examined by Dr. Michael Collins, director of the sports concussion program at the University of Pittsburgh Medical Center.

After the game Tuesday, Drew told reporters, "If I can come back in two or three days and this is gone, praise God, then I can get going . . . I've got to kind of get this thing under control. That's the No. 1 goal and we'll go from there."

Bird starts against lefty

Greg Bird started at first base Wednesday night against lefthanded starter Wade Miley mainly because Girardi didn't have a righthanded-hitting option. Backup catcher John Ryan Murphy had taken ground balls there for only one day and Chris Young never has played first. "I think it would probably be too risky at this point," the manager said.

Major milestone

The historical significance of the Yankees seeking their 10,000th franchise win against the Red Sox was not lost on the visitors.

"It's a great history and it's a lot of wins. It gives the organization something it should be very, very proud of," said Boston's interim manager Torey Lovullo, who played 22 games for the Yankees in 1991.

Before the game, he added, "Yes, we are aware of that milestone that they are about to reach. It's going to happen at some point, we're just hoping it doesn't happen while we're here."

No other American League team has won 10,000 games. In the National League, which is older, the Giants, Cubs, Braves, Dodgers and Pirates all have reached that mark.
