Mario Lemieux and the Pittsburgh Penguins are making opponents pay attention to the NHL's crackdown on penalties.

Lemieux scored a goal and had two assists to lead the Penguins to a 4-1 victory over the host Ottawa Senators last night.

Dick Tarnstrom, Jan Hrdina and Alexei Kovalev also scored for Pittsburgh, which won its third straight to improve to 6-2-2.

The Penguins scored twice in five power-play opportunities. Pittsburgh has scored 17 power-play goals in 10 games and leads the league with a 27.8 percent success rate with the man advantage.

"We've always had a good power play in Pittsburgh but not like this one, so far, early in the season," Lemieux said. "We've spent a lot of time on it and we talk a lot about it, and the guys know exactly what their jobs are -- how we're going to react in certain situations."

Lemieux increased his league-leading points total to 23, setting up goals by Tarnstrom and Kovalev before scoring his sixth of the season on a power play 2 minutes 56 seconds into the third.

"The personnel we have, everybody can handle the puck and see the ice very well so it makes it easy," Lemieux said.

* LIGHTNING 3, RANGERS 0: Nikolai Khabibulin made 24 saves for his 29th career shutout as Eastern Conference-leading Tampa Bay won at home.

It was Khabibulin's first shutout in 34 games, dating from a 1-0 victory over the Rangers last Jan. 28.

"When a goalie stands on his head like he did and gives you a chance to win, you need to step up," Lightning Coach John Tortorella said. "He certainly gave us a chance."

Tim Taylor had a first-period goal for Tampa Bay, which opened the season a franchise-best 7-1-2. Fredrik Modin and Vincent Lecavalier scored late third-period goals.

* HURRICANES 4, ISLANDERS 2: In Raleigh, N.C., Sami Kapanen, Jeff O'Neill and Niclas Wallin scored during an 111/2-minute stretch in the second period as Carolina rallied for the win.

The Hurricanes overcame a 2-0 first-period deficit to win the first of a nine-game homestand and improve to 4-1-1 in their last six games.

* BLUES 7, PREDATORS 0: Reed Low, Al MacInnis and Keith Tkachuk scored on successive shots during a four-goal second period as host St. Louis won its sixth straight.

The Blues are 6-0-1 since losing the season opener, despite being forced to use four goalies because of injuries, and are tied the Red Wings for first place in the Central Division.

St. Louis's 6-1-1 overall record is the second-best start in franchise history after the 1997-98 team began 7-1-1. St. Louis scored seven goals for the second time this season.

* PANTHERS 3, STARS 2: In Dallas, Valeri Bure scored 3:21 into overtime, and backup Jani Hurme made 42 saves for Florida.

Bure took possession in the right corner as Dallas goalie Marty Turco skated out of his net to play the puck, leaving Turco out of position. Bure skated around the back of the net and stuffed in his second goal of the season.
