Defenseman Ian White broke a tie with 1 minute, 22 seconds to play with his third goal in four games and the Toronto Maple Leafs held on for a 4-3 victory over the Stanley Cup champion Pittsburgh Penguins last night.

White gave the visiting Maple Leafs their fourth lead of the game, beating goalie Marc-Andre Fleury with a slap shot from the right point.

"I think we kept a quiet confidence after [Pittsburgh's tying goal]," White said. "We didn't get deflated, and that's a pretty deflating time to get one scored against you. But we kept on pushing, had a couple more hard shifts, and it paid off."

Lee Stempniak had a goal and two assists, and Luke Schenn and Jason Blake also scored for the Maple Leafs. The victory was only Toronto's second in its past seven games.

Pittsburgh's Mike Rupp had tied the score at 3-3 53 seconds before White's goal. Matt Cooke and Sidney Crosby also scored for the Penguins, who lost in regulation for only the third time since Nov. 27.

Penguins-killer Blake scored his 25th goal and 48th point in 48 games against Pittsburgh - his most versus any NHL team - on a wrist shot from the slot that beat Fleury with 4:53 to go in the second.

"I think our execution wasn't there, and that's pretty typical when you come back from a break and we were playing a team who had already played and had their legs under them a little bit," Crosby said. "We worked hard, but it seems like we just couldn't execute the way we needed to."

In other games:

* At Sunrise, Fla., Marco Sturm broke a third-period tie, and Tim Thomas made 25 saves in the Boston Bruins' 2-1 victory over the Florida Panthers, the bruins' third straight victory.

Sturm scored at 4:39 of the final period, tipping the puck past Scott Clemmensen for his 11th goal of the season. Clemmensen started in place of Tomas Vokoun, the Florida regular who had shut out the Bruins in their last two meetings.

Dominic Moore opened the scoring for Florida at 4:09 of the first period, and Michael Ryder tied it late in the second. That was the Bruins' first goal against Florida in three games over two seasons. Vokoun beat the Bruins 2-0 on Feb. 21 and 1-0 on Nov. 12.

* At Chicago, Patrick Kane scored with 43.4 seconds to play, his second goal of the game, capping a wild third period and lifting the Blackhawks to a 5-4 victory over the Nashville Predators.

John Madden scored twice in the third for the NHL-leading Blackhawks, who beat Nashville on consecutive nights to open an eight-point lead in the Central Division over the second-place Predators.

The Blackhawks have won seven of their last eight games and their 55 points are the most they've had after 38 games since the 1982-83 team had 56, back when points were not awarded for losses after regulation.

* At St. Louis, Tim Connolly scored twice in Buffalo's three-goal third period and had an assist in the Sabres' 5-3 victory over the Blues.

* At Calgary, Mason Raymond scored three times in a 14:15 span for a natural hat trick, and Roberto Luongo made 29 saves in the Vancouver Canucks' 5-1 victory over the Flames.

Raymond scored twice in a 34-second span late in the first period to give Vancouver a 4-1 lead, and completed the hat trick on a power play at 12:31 of the third. Henrik Sedin and Kyle Wellwood also scored for the Canucks. Jarome Iginla scored his 20th goal for Calgary.
