Prucha scored his first goal at 6:59 of the first, off assists from Brendan Shanahan and Fedor Tyutin, and made it 2-1 at 14:05 of the second on a play set up by Thomas Pock and Marek Malik. Florida's Steve Montador opened the scoring at 2:12 of the first.
Al Montoya and Stephen Valiquette split time in goal for the Rangers. Montoya made nine saves in relief of Valiquette, who stopped eight shots. Both allowed one goal.
