EDMONTON, Alberta (AP) — Radek Faksa had a goal and two assists, Roope Hintz scored the last of three power-play goals by Dallas and the Stars beat the Colorado Avalanche 5-4 on Sunday night, taking a 3-1 series lead in the Western Conference semifinal series.

The Stars, who led 3-0 in the first period before Colorado had its first shot on goal, saw their margin cut to one before Hintz was patient with the puck about 7 1/2 minutes into the third period. There were only a couple of seconds left on a power play when he scored on Dallas’ seventh shot during that segment after initially waiting for some traffic to clear.

Dallas then got a gift goal only 32 seconds later when Avalanche rookie defender Cale Makar, who had scored late in the second period, tried to clear a puck from behind his own net and flubbed the attempt. Goalie Pavel Francouz didn’t see it go in front of him, and Stars rookie Denis Gurianov knocked it in for a 5-2 lead.

John Klingberg had a goal and an assist for the Stars, who need one win to get to their first conference final since 2008. Game 5 is Monday night, a previously scheduled back-to-back though initially those consecutive games were supposed to be Games 5 and 6.

Colorado was within 3-2 on Makar’s goal with 25 seconds left in the second period, only 11 seconds after they went on a 5-on-3 advantage because of penalties against Blake Comeau (hooking) and Jamie Oleksiak (interference) at the same time.

Islanders 3, Flyers 1

TORONTO (AP) — Matt Martin and Leo Komaroz scored in the second period and the New York Islanders rallied to beat the Philadelphia Flyers 3-1 on Saturday night, taking a 2-1 lead in the Eastern Conference semifinal series.

Anders Lee also scored, and Semyon Varlamov had 26 saves to rebound after a rocky Game 3 that saw him benched in the first period.

The playoffs resumed after a two-day break to protest racial injustice, the latest twist in an unprecedented, pandemic-halted season. Game 4 is Sunday night.

Tyler Pitlick scored for the Flyers in the first period, and Carter Hart had 26 saves.

Pitlick’s wrist shot from the top of the right circle flashed past the glove of a screened Varlamov glove to give the Flyers a 1-0 lead 5:42 into the game. The play was set up by a puck battle behind the net won by Scott Laughton, who was able to power his way out and drop the pass off to Pitlick.

New York surged in the second period.

After a couple near misses by Mathew Barzal early, the Islanders’ center shoveled a pass out from the back boards to a wide-open Martin on the doorstep for the tying goal at the 7:12 mark.

Lightning 3, Bruins 1

TORONTO (AP) — Ondrej Palat scored twice, Andrei Vasilevskiy made 29 saves and Tampa Bay beat Boston to take a 3-1 lead in the second-round series.

Victor Hedman also scored a pinball, bouncing goal on goalie Jaroslav Halak, who has started every game since starter Tuukka Rask opted out of the playoffs in the middle of the first round. Halak, who was pulled last time out Wednesday, allowed three goals on 26 shots in Game 4.

Tampa Bay has won three in a row since losing the series opener. Palat has four goals in that time, including the Game 2 overtime winner.

Jake DeBrusk scored for Boston.

Golden Knights 3, Canucks 0

EDMONTON, Alberta (AP) — Robin Lehner stopped 32 shots and Vegas beat Vancouver to take a 2-1 lead in the Western Conference semifinal series.

Alex Tuch, got his seventh goal of the postseason, and Mark Stone and Zack Whitecloud also scored.

Lehner got his second career playoff shutout — and the second of the series. He blanked Vancouver 5-0 in the series opener and improved to 7-2 in the return-to-play tournament.

Jacob Markstrom made 31 saves for Vancouver.
