DENVER (AP) -Chris Mason made 28 saves for his sixth shutout of the season, helping the St. Louis Blues take the sixth playoff spot in the Western Conference with a 1-0 win over the Colorado Avalanche on Sunday in the regular-season finale.
In the playoffs for the first time in five years, the Blues - 9-1-1 in their final 11 games - will face Vancouver in the opening round.
Brad Boyes scored the only goal of the game early in the first period.
PHILADELPHIA (AP) - Sean Avery and Blair Betts scored third-period goals to rally New York, spoiling Philadelphia's shot at home-ice advantage against Pittsburgh in its opening playoff series against Pittsburgh.
Brandon Dubinsky scored two goals for the Rangers, set to open the playoffs against Southeast Division champion Washington.
Dubinsky's second goal was short-handed, wrecking Philadelphia's shot at becoming the first team in NHL history to play an entire season without allowing one.

Chicago, a 4-2 winner over the Red Wings on Saturday in Detroit, was 6-0-1 in its final seven games. They will open the playoffs against Calgary, while the defending Stanley Cup champion Red Wings will face Columbus in the first round.
