Mark Stone scored on a breakaway with 3:49 remaining in overtime to cap a four-point night and the Vegas Golden Knights became the first NHL team to hit the 20-win mark this season, beating the Calgary Flames 5-4 on Tuesday in Las Vegas.

Stone took a stretch pass from Jack Eichel and then fired a wrist shot from the left circle past the glove of Calgary goalie Dustin Wolf and inside the far post for his second goal of the game and 10th of the season. It was the sixth career overtime goal for Stone.

Jonathan Marchessault had three assists, William Karlsson and Chandler Stephenson each had a goal and an assist and Ivan Barbashev also scored a goal for the Golden Knights. Vegas won its fourth straight game while extending its point streak to nine games (6-0-3).

Logan Thompson made 27 saves for the victory.

Yegor Sharangovich scored two goals, Nazem Kadri had a goal and an assist, and MacKenzie Weegar also scored for Calgary, which lost its third straight game. Wolf finished with 34 saves.

Calgary, playing the second game of a back-to-back set that started with a 6-5 loss at Colorado on Monday, took a 1-0 lead at the 6:27 mark of the first period on a slap shot by Weegar from the top of the right circle inside the near post.

Vegas tied it a little over seven minutes later on a power play. Stephenson scored on a backhand rebound shot to extend his goal streak to three games.

The Flames regained the lead at 2:37 of the second period when Connor Zary's shot from the high slot bounced into the goal off Kadri's left side.

The Golden Knights tied it 2-2 less than three minutes later when Barbashev ripped a wrist shot from the high slot past Wolf's blocker side.

But Calgary, despite being outshot 15-4 in the period, went back ahead 3-2 at the 17:58 mark. Sharangovich came down the right wing on an odd-man rush and fired a wrist shot that hit Thompson's glove and then rolled into the net.

Vegas tied it for the third time early in the third period on a power-play goal by Stone. He took a pass from Karlsson while cutting down the slot and then put a backhand shot under Wolf's right arm.

Karlsson then gave Vegas its first lead of the game, 4-3, with 3:46 left when he one-timed a Stephenson pass from the right circle past Wolf's glove side.

Calgary, which pulled Wolf for an extra attacker with 1:42 to go, tied it with 59.3 seconds left when Sharangovich deflected Noah Hanifin's point shot past Thompson for his ninth goal of the season.
