The Avalanche received their third power play just 1:20 into the frame as Nico Sturm - who was on the team's 2022 Stanley Cup-winning roster - went to the box for hooking. The Avs didn't manage to convert and Georgiev came up with a timely shorthanded chance from Marc-Edouard Vlasic.
Shortly after, the Sharks tilted the ice as received their first power play of the night - at 4:59 as MacDermid was called for tripping - and they capitalized to trim their deficit down 3-2 at 5:50.
On a tic-tac-toe passing play, Logan Couture sent a pass to the near post for Gushchin. The Sharks winger played the puck to the net front where Peterson chipped his shot over Georgiev's stick and right shoulder for the power-play strike.
Soon enough, the Sharks secured a 3-3 equalizer. Noah Gregor picked up a pass from MacDonald and carried it around the net and attempted a wraparound, but Georgiev denied it. The rebound shot out into the low slot where Labanc corralled it, turned past Samuel Girard and fired a wrist shot past Georgiev's glove in tight for the equalizer at 7:11.
After the power-play goal, San Jose came to life and dominated the offensive zone, but the Avalanche managed to hang on. With the game headed to overtime, Colorado officially clinched its spot in the 2023 Stanley Cup Playoffs.
In overtime, Toews intercepted a pass and sprung MacKinnon for a breakaway. The centerman carried the puck between the circles, stickhandled and roofed his shot past Kahkonen for the OT game winner and his 100th-career point.
