Piatti opened the scoring in the 51st minute when he powered a left-footed shot past goalkeeper Luis Robles. Eight minutes after New York tied it, Piatti iced it with his right foot. Dominic Oduro raced down the left sideline on a breakaway and waited for help. Didier Drogba trailed up the middle, drew two defenders and found an open Piatti for a close-range shot.

New York needed a two-goal home win to advance to its third straight conference title game after being shut out 1-0 in Game 1.

Bradley Wright-Phillips, who won his second MLS Golden Boot in the last three seasons with 24 regular-season goals, scored on a deflected shot in the 78th minute.
