ST. LOUIS - Brad Boyes scored the lone goal early in the third period, and Chris Mason made 22 saves to shut out the Chicago Blackhawks for the second straight time in the St. Louis Blues' 1-0 victory Friday night.
Boyes scored on a 4-on-3 power play, converting a one-timer from the left circle 57 seconds into the third period. Chicago's Adam Burish was in the box for a slashing penalty at the end of the second period after offsetting roughing penalties on the Blues' Barret Jackman and the Blackhawks' Colin Fraser.
Andy McDonald's cross-ice feed to Boyes into the left circle led to the shot that Cristobal Huet seemed to get a piece, but still found its way into the net.
Mason, who shut out Chicago 2-0 on Jan. 21, helped the Blues break a modest two-game losing streak in which they blew two-goal leads in each game.
The Blackhawks wrapped up an eight-game trip with the loss
The first period between the Central Division rivals was pretty quiet, with the Blues having the best scoring chance. But Huet made a glove save on Boyes with 7:27 to play in the period after the Chicago gave the puck up in its own zone.
Chicago also had a chance 11:19 left in the second, but Andrew Ladd's backhander hit the right post, and Mason denied him with a glove save on the rebound.
Notes: The Blackhawks went 5-3 on the longest trip of the season by an NHL club. Chicago returns home Saturday night for a game against Dallas, its first home game since losing to the Blues on Jan. 21. ... The Blues improved to 4-0-1 against the Blackhawks this season.
