The Dallas Stars and Pittsburgh Penguins played the sixth scoreless tie in the NHL this season Sunday, a tight-checking battle of division leaders.

Dallas, leading the Central Division, had won its previous four games. The Stars improved their league-leading point total to 95 despite missing six regulars due to injuries.Pittsburgh, the leader in the Northeast, is 4-1-1 in its last six games.

The Penguins last scoreless draw came this season on Jan. 20 against Ottawa. The Stars' previous 0-0 game was on Feb. 24, 1994, against Los Angeles.

Penguins goalie Tom Barrasso made 28 saves for his seventh shutout. Dallas' Ed Belfour needed 20 stops for his ninth shutout, extending the Stars single-season record.

Dallas' Jamie Langenbrunner had the best scoring chance of the overtime but Barrasso stopped his backhander from in front with 2:10 left.

The Stars thought they'd taken the lead with 12:42 left in a scoreless game, but the goal was disallowed after video review when it was ruled that Joe Nieuwendyk kicked the puck into the net.

Each team managed only four shots on goal in a cautious first period. The Penguins didn't get their first attempt on net until there was 10:45 left in the opening period.

Both goalies were sharp in the scoreless second period, with Belfour stopping Jaromir Jagr on a breakaway with 2:41 remaining.

CHICAGO 1, BOSTON 0: At Chicago, Jeff Hackett stopped 26 shots for his second straight shutout - and eighth of the season.

Defenseman Cam Russell's first goal of the season, at 3:06 of the first period, helped the Blackhawks post their fourth straight victory.

Chicago snapped Boston's four-game winning streak and the Bruins' seven-game road unbeaten string. The Blackhawks are 5-0-1 in their last six meetings against Boston and 10-1-1 in the last 12 games between the teams.

Hackett, who blanked Montreal 1-0 Thursday, has not surrendered a goal in 127 minutes, 9 seconds.
