Semyon Varlamov tied the franchise single-season record for goalie wins held by Colorado Avalanche coach Patrick Roy and Paul Stastny had another big game in his hometown in a penalty-filled 4-0 victory over the St. Louis Blues on Saturday.

Stastny had a goal and two assists and Nathan Mackinnon had a goal and an assist for Colorado, which has won six in a row and has 106 points, third-most in franchise history. Roy became the fifth coach in NHL history to win 50 games in his first season.

Varlamov made 31 saves for his second shutout of the season and NHL-leading 40th win, matching Roy's total in 2000-01. The Avalanche reached 50 wins for the second time in franchise history and tied the franchise mark with 24 road victories.

The Blues fell two points behind Boston, which beat the Flyers 5-2, for first place overall. They've been dependent on goalie Ryan Miller with Vladimir Tarasenko out since mid-March with a hand injury and Alexander Steen also sidelined, and scored two or fewer goals for the seventh time in 10 games.
