Ellsbury popped up on the slide and briefly stumbled before getting back to the bag, but he was called out on the initial slide by second-base umpire Paul Schrieber, who ruled that Ellsbury had been tagged by shortstop Xander Bogaerts.
Yankees manager Joe Girardi challenged the call, and after a review of one minute and 46 seconds, it was determined that Ellsbury slid in safely ahead of Bogaerts' tag.
Ellsbury moved to third on a Teixeira groundout and scored on Carlos Beltran's single to center field, trimming Boston's lead to 3-2 at the time.
Girardi and the Yankees have made 20 challenges this season; 15 have been overturned, three have been confirmed and two have been ruled to stand.
