The Stanley Cup Playoffs continued on Friday with two games, both in the Eastern Conference.
Justin Williams scored the winning goal 64 seconds into overtime as the Washington Capitals defeated the visiting Toronto Maple Leafs 2-1 in game five of their conference quarterfinal series.
The Caps can finish off the Leafs with a game-six victory in Toronto on Sunday.
Sean Kuraly's second goal of the game was the winning tally at 10:19 of the second overtime period as the Boston Bruins came back from two goals down to upend the Ottawa Senators 3-2 on the road in game six of their opening-round series.
The Senators, who still lead the series three games to two, can finish off the Bruins on Sunday afternoon with a game-six victory on Boston ice.
