The Colorado Avalanche pushed their second-round series with the San Jose Sharks to a seventh game following a 4-3 overtime victory Monday at Pepsi Center in Denver.

Gabriel Landeskog, who was without a point in the previous three games, scored the winning goal for Colorado at the 17:28 mark of the first overtime period. Fresh off making 37 saves in a losing effort Saturday, Philipp Grubauer stopped the Sharks 19 times in Game 6.

Landeskog did a little bit of everything to help set up the goal. He dumped the puck into the Sharks' zone before pressuring Erik Karlsson along the boards. The Sharks were unable to clear the danger, and Cale Makar found Landeskog in front of the net.

With the way the game had unfolded, some Avs fans likely wondered whether the team could grab yet another go-ahead goal.

Marc-Edouard Vlasic sent the game into overtime by scoring with only 2:28 remaining in regulation. It was part of a prolonged attacking spell by the Sharks, who were throwing everything they had at Avs goaltender Grubauer.

All told, Colorado led three different times, only to see the Sharks come back and tie the score.

With 4:05 elapsed in the second period, Tyson Jost got Colorado on the board, and the Avs' advantage held for a little over 10 minutes before Vlasic canceled it out.

J.T. Compher brought the home crowd back to life. With only 9.8 seconds remaining in the period, though, Brent Burns' wrist shot eluded Grubauer for another San Jose equalizer.

Finally, in the third period, the Avalanche appeared to be free and clear. Compher made Martin Jones look foolish to put the Avalanche ahead 3-2. The Sharks goaltender was left sprawled out on the ice as he watched Compher's shot hit the back of the net.

Much has been made of Nathan MacKinnon's production in this series. After getting eight points in the first round against the Calgary Flames, MacKinnon has five points through six games against the Sharks.

The sixth-year center is clearly exerting a tremendous amount of effort.

For whatever reason, things aren't coming off for MacKinnon, and he isn't the only star to provide underwhelming returns. Landeskog was struggling, and Mikko Rantanen is without a goal in the second round.

Normally, having three of your top attackers underperform would spell doom in the postseason. On Tuesday, Compher stepped up to lead the Avs' offense. The 24-year-old was an unlikely Game 6 hero.

Colorado can't count on a repeat of that in Game 7. The team will hope Landeskog's goal shook the 26-year-old out of his brief funk because more will be required of him, MacKinnon and Rantanen in order to win a winner-take-all game in enemy territory.

The Sharks, meanwhile, won't panic too much. They've already overcome a 3-1 series deficit to the Vegas Golden Knights, overturning Vegas' three-goal lead in the third period of Game 7 before prevailing in overtime.

What's Next?

The series moves back to San Jose for Game 7 on Wednesday. One of the Dallas Stars or St. Louis Blues will have already punched their ticket into the Western Conference Final by then. The two teams have a Game 7 of their own on Tuesday in St. Louis.
