The St. Louis Blues erased a pair of late third-period deficits before Tyler Bozek scored 3:38 into overtime to give them a 5-4 victory at Colorado in the Stanley Cup second-round series. Bozek capped a frantic rally in which teammate Robert Thomas tied the game with 54 seconds left in regulation. Nathan MacKinnon’s third goal of the night put the Avalanche ahead late in the third, but the Blues sent the series back to St. Louis for Game 6 on Friday.
