The Red Sox led 6-1 after 4 1/2 innings but the Yankees chipped away at the lead until Mark Teixeira unleashed a two-run homer in the eighth to tie it.
Ciriaco followed by lining a shot that Yankees center fielder Curtis Granderson misjudged -- the ball went over his head and to the wall for a triple, giving Boston a 7-6 lead.
Ciriaco came home on Dustin Pedroia's sacrifice fly and Alfredo Aceves notched his 22nd save for Boston, which evened its three-game series and broke a three-game skid against New York.
