John Tavares scored his second goal of the game with 9 minutes, 49 seconds left, and the host New York Islanders tied their first-round series with the Pittsburgh Penguins on Tuesday night with a wild 6-4 victory.
Only the final lead was safe in Game 4.
Tavares slammed in his own rebound in front after Brad Boyes fed him following a turnover by Penguins star Evgeni Malkin. It was the Islanders' third one-goal advantage in the game and the one that earned them a 2-2 tie in the highly entertaining series that has featured 5-4 and 6-4 finishes at Nassau Coliseum.
Tavares was serenaded with cheers of "M-V-P" from the frantic crowd that is believing an upset is possible. Casey Cizikas shoved in a shot with 1:16 left to add some much-needed insurance.
Brian Strait, captain Mark Streit, and Kyle Okposo also had goals, and Evgeni Nabokov made 27 saves for the eighth-seeded Islanders.
Kyle Turris scored 2:32 into overtime, lifting the Ottawa Senators past the visiting Montreal Canadiens, 3-2, to grab a three-games-to-one lead in their playoff series.
Turris' shot from the sideboards sneaked past Montreal backup goalie Peter Budaj, who came on for the injured Carey Price at the start of overtime.
Cory Conacher scored with 22.6 seconds to go in regulation to force overtime. Mika Zibanejad had the other goal for the Senators, who got 26 saves from Craig Anderson.
P.K. Subban and Alex Galchenyuk scored 62 seconds apart in the second period for Montreal. Price made 30 saves two nights after allowing all six goals in Ottawa's 6-1 win in Game 3.
