Mitch Marner scored a hat trick and also had two assists as the Vegas Golden Knights rallied for a 6-3 victory over the Calgary Flames on Thursday night in Las Vegas.

It was the sixth five-point game of Marner's career and his fourth career hat trick.

Ivan Barbashev had a goal and two assists and Pavel Dorofeyev and Brett Howden also scored for Vegas (34-26-16, 84 points), which remained three points behind co-leaders Anaheim and Edmonton in third place in the Pacific Division with six games remaining.

Shea Theodore had two assists to hit the 400-point mark in his career, and Carter Hart, making his first start since Jan. 8 after missing 33 games with a lower-body injury, made 19 saves as the Golden Knights won their second straight game under new head coach John Tortorella.

Blake Coleman scored two goals and Morgan Frost also scored for Calgary (31-36-8, 70). Dustin Wolf finished with 28 saves.

Calgary took a 1-0 lead at the 7:41 mark of the first period when Frost intercepted a pass in the neutral zone and then ripped a shot from the slot past Hart's glove side.

Vegas tied it early in the second period when Marner, stationed by the right post, deflected in a Theodore point shot.

The Flames regained the lead when Coleman finished an odd-man rush with Mikael Backlund with a shot over Hart's right pad.

The Golden Knights came right back to tie it just 2:04 later with Marner's second goal of the game, a one-timer from the low slot off a Rasmus Andersson pass.

Coleman put Calgary back ahead, 3-2, midway through the period when he finished another odd-man rush, firing a shot from the left circle that caromed off Hart's shoulder and then off the far right post and into the net.

Vegas tied it near the end of the period on a power-play goal by Dorofeyev, a one-timer from the middle of the right circle off a Marner setup. It was Dorofeyev's team-leading 35th goal, tying a career high and also snapping an eight-game goal drought.

Following a 26-minute delay to start the third period to repair a small ice patch below the Calgary goal line, Howden gave the Golden Knights their first lead of the game with 7:40 remaining when he snapped a shot from the slot past Wolf's blocker side.

Barbashev then made it 5-3 with 5:01 left, putting in a rebound of a Marner shot after Wolf misplayed a puck behind his net.

Marner then capped the scoring with a wraparound goal with 1:29 left to complete his hat trick.
