TAMPA, Fla. (AP) — Juraj Slafkovsky scored his third power-play goal 1:22 into overtime and the Montreal Canadiens beat the Tampa Bay Lightning 4-3 in Game 1 of their first-round series on Sunday night.

Slafkovsky fired a slap shot from the left circle that beat Andrei Vasilevskiy to the far side for the hat trick.

Game 2 is Tuesday night at Benchmark International Arena, where Tampa Bay has lost eight of its last nine home games in the postseason.

Josh Anderson also had a goal for Montreal and rookie goalie Jakub Dobes made 20 saves.

Brandon Hagel scored two goals and Darren Raddysh also scored for Tampa Bay.

The Lightning have been knocked out of the playoffs in the first round three straight seasons after falling two wins shy of a three-peat in 2022.

The Canadiens, coached by Lightning icon and Hockey Hall of Famer Martin St. Louis, are seeking their first Stanley Cup since winning their NHL record 24th in 1993. They haven’t won a playoff series since the Lightning beat them in the Cup Final in 2021.

Hagel’s power-play goal — a tip-in off a precise pass by Jake Guentzel 8:58 into the third — tied it at 3-3 a few minutes after Slafkovsky put Montreal ahead.

Slafkovsky’s shot from the high slot slid under Vasilevskiy’s left pad for a short-lived lead. He one-timed a perfect seam pass from Ivan Demidov into the net from the right circle to make it 2-2 in the final minute of the second.

Raddysh tied it at 1 with a powerful slap shot in the second. The Lightning quickly went ahead 2-1 just 29 seconds later when Hagel picked up a loose puck from the side of the net and backhanded a shot past Dobes.

Montreal’s fourth line gave the Canadiens a 1-0 lead in the first when Anderson flipped a top-shelf shot into an open net.

Anderson had another goal overturned by video review midway through the second period. He deflected Mike Matheson’s slap shot past Vasilevskiy but it was waved off because his stick was above the crossbar.

WESTERN CONFERENCE

AVS 2, KINGS 1

Logan O’Connor scored for the first time in more than a year, Scott Wedgewood stopped 24 shots in his first Stanley Cup playoffs start and the top-seeded Colorado Avalanche beat the Los Angeles Kings 2-1 in Game 1 on Sunday.

O’Connor’s third-period tally was his first since March 31, 2025. He missed most of the season with a hip injury. Artturi Lehkonen had a second-period goal for the Presidents’ Trophy-winning Avalanche.

Wedgewood got the nod in net over Mackenzie Blackwood after leading the league in goals-against average and save percentage. Wedgewood made four career playoff appearances in relief before Sunday’s start.

Game 2 is Tuesday night in Denver.

Artemi Panarin scored a power-play goal with 2:22 left to make it 2-1. Shortly after, forward Joel Armia was called for high-sticking and the Kings were unable to tie it up.

Anton Forsberg stopped 28 shots in his NHL postseason debut.

Nathan MacKinnon had an assist on Lehkonen’s goal to give him 32 career points in Game 1s. He trails only Joe Sakic (42) for the most Game-1 points in franchise history.

The game got chippy in the third period, with Cale Makar taking a shove to the back by Adrian Kempe. Captain Gabriel Landeskog later stood up for Makar and got into it with Kempe. Both drew roughing calls.

There were a combined 84 hits.

Colorado nearly scored earlier in the second when O’Connor sent a shot past Forsberg. But as the horn sounded, the officials signaled no goal. It was ruled Jack Drury made contact with Forsberg following a collision with Drew Doughty. The Avalanche challenged but the call stood.

GOLDEN KNIGHTS 4,MAMMOTH 2

Nic Dowd redirected Noah Hanifin’s shot from the point to put Vegas ahead at 7:20 of the third period and the Golden Knights beat the Utah Mammoth 4-2 in Game 1 of their first-round series in Las Vegas.

Game 2 is Tuesday night in Las Vegas.

The Golden Knights, who twice trailed before scoring three third-period goals, have not lost in regulation since John Tortorella (8-0-1) took over as coach.

The Mammoth lost in the franchise’s first playoff game since 2021. They are in their second season in Utah after leaving Arizona.

Colton Sissons had a goal and assist for the Golden Knights and Mark Stone and Ivan Barbashev also scored. Carter Hart stopped 32 shots. Hanifin had two assists.

Logan Cooley and Kevin Stenlund scored for the Mammoth. Karel Vejmelka, playing in his first playoff game after five years in the Utah/Arizona organization, made 27 saves. Captain Clayton Keller, who closed the regular season with 16 assists over a 10-game streak, failed to record one in this game.
