"Just go to the net and good things happen I guess," Schlemko said. "The rebound came right to me, and I just had to tap it in. I'll take those any day."

Mikhail Grigorenko and Francois Beauchemin scored for Colorado (13-29-2).
The Sharks are 15-1-0 in their past 16 home games against the Avalanche. Colorado is 2-14-1 in its past 17 games this season.
"I think you got a desperate team," Sharks coach Peter DeBoer said of the Avalanche. "They're better than their record. They're very skilled. And for us, this is a tough game. This was our fifth game in eight nights. It's been a long week. I feel the fatigue and I haven't played a game. I'm just coaching. We found a way to win. It was ugly, but we found a way."
Martin made 27 saves and helped keep Colorado in the game.
"It's the biggest thrill of my life so far," Martin said. "I'll never forget it. The first few minutes were tough, but after that I settled in."

The Avalanche tied it 2-2 on Beauchemin's unassisted goal at 10:24 of the third period when he beat Jones from the left circle with a slap shot inside the left post. It was his second goal of the season.

"I liked the way the team played. We're starting to get some traction on the way we want to play. We don't always get the results. A couple of mistakes ended up in our net." -- Avalanche coach Jared Bednar
"When we're on our game, we're making it tough with grind time and traffic at the net, some chances. Tonight, we didn't have as many as we could have had. We'll try to find a little bit more for next game." -- Sharks captain Joe Pavelski
