OTTAWA, Ontario — Dale Weise scored the tying goal late in the third period and then won it 8:47 into overtime, leading the Montreal Canadiens to a 2-1 victory Sunday night in their first-round playoff series.

Montreal has a chance to complete a four-game sweep Wednesday, with Game 4 in Ottawa.

Weise skated in on the left side and beat Craig Anderson with a shot inside the near post. Many of the Senators fans in the stands urged officials to call for a hand pass by Brandon Prust on the play, but the goal stood – and the Canadiens have a commanding lead.

Weise sent the game to overtime with his goal with 5:47 remaining in the third. Torrey Mitchell assisted on both goals, and Carey Price made 33 saves.

Clarke MacArthur opened the scoring for the Senators at 11:28 of the first period. Anderson, making his first start of the playoffs after Andrew Hammond started the first two games, made 47 saves in the loss.

Montreal dominated at times in the second and third periods, outshooting Ottawa 31-15 through the final 40 minutes of regulation.

The Senators scored when Montreal defenseman P.K. Subban went for a hit on Erik Karlsson, and Mark Stone was able to slip the puck in front of the Montreal net, where two Ottawa players were parked. MacArthur deked Price and slid in is second of the series.

The Canadiens turned it around in the second, outshooting Ottawa 19-6, but couldn’t get one past Anderson.

It took until their 36th shot, at 14:13 of the third, for Weise to tie the game as he slapped one into an open side off a pass from Prust with a crowd of players jostling near the net.

BLACKHAWKS 4, PREDATORS 2: Jonathan Toews had a goal and an assist, and Chicago used a three-goal second period to beat Nashville at home for a 2-1 lead in their first-round playoff series.

Goalie Scott Darling made 35 saves to help Chicago win for the 20th time in its last 24 postseason home games.
