Defenseman scores winner in overtime for Blues

ST. LOUIS -- Carlo Colaiacovo happened to be in the right place at the right time Saturday night.

Colaiacovo deflected in a shot from Patrik Berglund 3 minutes, 18 seconds into overtime to give the Blues a 3-2 win over Colorado.

David Perron added two goals and an assist, and T.J. Oshie also had two assists to help the Blues win for the fourth time in five games and improve to 15-0-3 in their last 18 at home.

Colaiacovo, who was stationed 20 feet from the net, got his elbow on Berglund's drive, re-directing it behind goalie Semyon Varlamov. It wasn't a picture-perfect tally, but Colaiacovo, who has two goals this season, will take it.

"I didn't need my stick to put it in," Colaiacovo said jokingly. "I felt it glance off my elbow. I didn't care who got it. I was just happy that it went in."

St. Louis, which is among the NHL's best home teams at 23-3-4, has recorded at least one point in a franchise-record 18 straight games.

Colaiacovo's 30th career tally helped the Blues improve to 15-0-3 during that stretch. They have outscored their opponents 53-30 during the home-ice run.

"We battled hard tonight and played an excellent game," Colaiacovo said. "At the end of the day, we found a way to win. That's one thing about us. We've been finding a way to do it at home."

Colaiacovo broke a 37-game scoreless drought with his fourth shot on goal of the night.

"I didn't really have any other choice but just to throw it on the net," Berglund said. "Luckily, it got through and it went in. It's nice to get out of here with two points."

Colorado defenseman Erik Johnson said the puck bounced off several players on the way to the net.

"It hit two guys, including me," Johnson said. "That's just how it bounces sometimes."

Johnson and Shane O'Brien scored for the Avalanche, who snapped a two-game winning streak and dropped their sixth in eight games.

O'Brien put Colorado ahead 1-0 midway through the first period before Perron scored twice in a span of 4:05 later in the first.
