PITTSBURGH -- With the Colorado Avalanche trailing late in the third period Monday, captain Gabriel Landeskog scored two goals, one in the third and another in overtime, to give them a 4-3 win against the Pittsburgh Penguins at PPG Paints Arena.
After helping to send the game into overtime with a power-play goal to tie it 3-3 late in the third period, Landeskog scored 22 seconds into overtime by tipping a fluttering puck by goalie Marc-Andre Fleury, who made 27 saves.
"I think the most important thing is getting the two points, at the end of the night," Landeskog said. "Sure, it feels good to contribute, but at the end of the day, it's a work ethic that you need to bring and the small details that you need to do on a daily basis to get the guys to follow you out there."
Landeskog's third-period goal erased the one-goal lead Trevor Daley gave the Penguins 9:12 into the third.
After Evgeni Malkin's apparent goal was waved off 7:07 into the third period following a coach's challenge, Daley gave the Penguins a 3-2 lead on Pittsburgh's second power-play goal. Matt Cullen set up Daley for a slap shot he sent by goalie Calvin Pickard, who made 28 saves in his first start of the season.
The Avalanche won the first game of a four-game road trip after defeating the Dallas Stars 6-5 in their season opener Saturday.
The Penguins won two of three games on their season-opening homestand despite being without center Sidney Crosby (concussion).

Phil Kessel scored his second power-play goal in as many games to open the scoring 8:57 into the first period. He shot past defensemen Francois Beauchemin and Erik Johnson before beating Pickard through the five-hole.
Cullen extended the lead 36 seconds later. After the puck slid out of the corner, Cullen retrieved it and drove to the net before shooting off Pickard, collecting his rebound and sending a wrist shot into the left side of the net.
With the goal, Cullen is the fourth-oldest player to score a point for the Penguins (39 years, 350 days).
"[Cullen] just plays the game the right way, for me," Penguins coach Mike Sullivan said. "He plays hard. He's a smart player. We can use him in all situations."
Fellow 39-year-old Jarome Iginla cut the Penguins lead in half with 3:33 remaining in the first period. The Avalanche went on a 5-on-3 power play for 1:11 after Penguins forward Chris Kunitz hooked Nathan MacKinnon with Nick Bonino already in the penalty box.
Iginla scored from the right circle 1:23 before Patrick Wiercioch tied it 2-2.

Unsung moment of the game
Avalanche coach Jared Bednar challenged after Malkin seemed to give the Penguins a 3-2 lead 7:07 into the third. Malkin skated through the crease with Colorado defenseman Fedor Tyutin falling behind him, collected a shot-pass from Kessel that ricocheted off the end boards and shot behind Pickard and by Tyutin. But following a video review, it was ruled Malkin interfered with Pickard.
