Mikko Rantanen scored at 2:07 of overtime and the Colorado Avalanche beat the Vegas Golden Knights 3-2 in Game 2 of the West Division final in Denver on Wednesday night.

Tyson Jost and Brandon Saad also scored goals, Samuel Girard had two assists and Philipp Grubauer stopped 39 shots for the Avalanche, who lead the series 2-0.

Colorado is the third President's Trophy winner to start a postseason 6-0. The 1994 New York Rangers and the 1999 Dallas Stars both did it on their way to winning the Stanley Cup.

Alec Martinez and Reilly Smith had goals, Shea Theodore added two assists and Marc Andre-Fleury had 22 saves for the Knights.

Game 3 is Friday night in Las Vegas.

The Avalanche got a power play 44 seconds into overtime when Smith was called for slashing. Nate MacKinnon had the puck on the left side of the Knights' zone and sent a pass across to Rantanen. His snap shot went off Fleury's left shoulder and in for his third goal of the playoffs.

Saad gave Colorado a 1-0 lead when his whiffed shot crossed up Fleury and went through his pads at 3:39 of the first.

It was Saad's fifth goal of the playoffs.

The Knights got even on a power play midway through the first. Max Pacioretty had the puck near the left circle and sent a pass to Martinez at the opposite circle, and his one-timer beat Grubauer at 9:32. It was Martinez's second of the postseason.

The Avalanche made it 2-1 on a power play when Jost got a pass from Girard in the slot and beat Fleury at 17:08. It was his second goal of the postseason.

Smith tied it in the second period when he roofed a backhander past Grubauer at 10:28 for his second of the playoffs.

Both teams had chances in the third period, with the best coming when Alex Tuch came out of the penalty box and went in alone on net, but Grubauer made a glove save to keep it 2-2.
