Yankees 4, Red Sox 3 (12): Raul Ibanez tied it in the bottom of the ninth with a two-run homer and singled in the winning run in the 12th as host New York maintained its lead in the American League East.

Andrew Miller (3-2) issued back-to-back walks to Francisco Cervelli and Curtis Granderson with two outs in the 12th before Ibanez ripped an opposite-field single through the left side for the walk-off run. The victory kept the Yankees one game clear of the Baltimore Orioles, who won earlier in the night.

Andrew Bailey came on with a 3-1 lead to close it in the ninth for the Red Sox and surrendered a leadoff single to Granderson before Ibanez entered as a pinch hitter and lined a 1-2 fastball into the stands in right to knot the game at 3-3.

Dustin Pedroia, who sat out Monday’s opener with a broken finger, decided to play through the pain and doubled in a run in the first to spark a two-run rally. James Loney’s solo home run off Rafael Soriano in the top of the ninth made it a 3-1 gap for Boston.

Derek Lowe (9-11) allowed a pair of hits in two scoreless innings to earn the win in relief for the Yankees.
