PITTSBURGH (AP) -- Montreal Canadiens goaltender Carey Price saw the NHL's leading scorer bearing down on him and figured he had maybe an inch or two over his right shoulder exposed. Thing is, an inch or two is all Sidney Crosby needs these days. Crosby beat Price with a laser to the top corner of the net late in the second period, Marc-Andre Fleury and Tomas Vokoun teamed up to stop 37 shots, and the Penguins extended their winning streak to 13 games with a 1-0 victory on Tuesday night. ''He's the best player in the world, so we got beat tonight by the best player in the world, by the perfect shot,'' Montreal coach Michel Therrien said. One Crosby delivered after a rare defensive breakdown by the Canadiens. Chris Kunitz found Crosby with a pretty cross-ice pass and Crosby did the rest. His 15th goal of the season turned out to be just enough to keep Pittsburgh's march through March going. ''To win that many, your goaltenders have to steal a game or two over that time period,'' Crosby said. ''Sometimes we've had tough periods and they've bailed us out.'' Against the surprising Canadiens, the Penguins needed both. Fleury stopped all 22 shots he faced, but did not play in the third period following a collision in front of the Penguins' net. Vokoun filled in and made 15 saves to give Pittsburgh just the fourth combined shutout in franchise history. Fleury appeared woozy after he was slammed into by teammate Tyler Kennedy and Montreal's Brian Gionta with less than a minute to go in the second. He laid on the ice for a moment to collect himself and managed to finish the final 49 seconds, but did not come out of the dressing room for the third. Pittsburgh coach Dan Bylsma said Fleury - who leads the NHL with 18 victories - would ''continue to be evaluated'' but offered no specifics. The Penguins are off until Thursday when they host Winnipeg. Given an entire intermission to warm up, Vokoun played solidly as Pittsburgh continued to tighten things up on the defensive end. The Penguins have allowed nine goals in their last nine games, the lowest total in the league over that span. ''I think guys are just really buying in to what our ultimate goal is here,'' defenseman Brooks Orpik said. ''We're winning games 2-1, 1-0 and guys are ecstatic.'' Price finished with 24 saves for the Canadiens, but couldn't stop Montreal from losing consecutive games for the first time this season. ''We've got to take the positive out of it,'' Price said. ''We keep playing the way we are, we're not going to lose that many games like that, so I think we've just got to stick to it.'' The Penguins welcomed back defenseman Kris Letang - who missed the last three games with a lower body injury - and didn't take long to put newly acquired forward Brenden Morrow to work. Bylsma sent the veteran winger out to take the opening faceoff and kept Morrow on the move, sending him out with different combination hoping to find a rhythm. Montreal did its best to prevent Pittsburgh from finding any, taking away open ice early and spending most of the time keeping Fleury busy. It hardly looked like the wild 7-6 overtime victory by the Penguins three weeks ago that kick-started what is now the second-longest winning streak in franchise history. Pittsburgh ripped off 19 straight during the 1992-93 season. Pittsburgh needed more than six minutes to register a shot, then again coach Michel Therrien knows a few things about handling the Penguins. He coached Pittsburgh to the 2008 Stanley Cup finals before Bylsma replaced him in February 2009. The Penguins won the Cup four months later. Tuesday night was Therrien's first game in Pittsburgh since his ouster. He politely nodded during a brief video tribute in the middle of the first period, but that would be the extent of the pleasantries on a night both teams hope served as a preview of a late postseason series for the top two teams in the Eastern Conference. Pittsburgh is gearing up for a Cup run, picking up Morrow from the Dallas Stars on Sunday then adding burly defenseman Doug Murray from San Jose on Monday. Murray won't arrive until Wednesday, but his new team certainly could have used him to clear some space in front of the net against the persistent Canadiens. Montreal spent most of the night driving at Fleury. He was more than equal to the task and spectacular at times, helped by a pair of shots by Canadiens forward Michael Ryder that hit off the post. ''You need a break if you want to win some hockey games,'' Therrien said. ''Certainly we didn't have any break tonight. Twice (we) hit the crossbar. It's a matter of inches to get out of the building with a win.'' NOTES: Montreal F Jeff Halpern played 14:51 in his debut with the Canadiens. Halpern was claimed off waivers last Saturday ... Orpik played in his 619th game, tying him with Ron Shock for the sixth-most games in franchise history. ... The Canadiens scratched D Tomas Kaberle and Fs Mike Blunden and Ryan White. ... The Penguins are 11-2 this season when playing without reigning NHL MVP Evgeni Malkin, who remains sidelined with an upper body injury.
