DETROIT (AP) -- Johan Franzen had a natural hat trick in a 3:26 span of the first period, scored a fourth goal in the third, and set a Red Wings playoff record with six points as Detroit stayed alive with a 7-1 rout of the San Jose Sharks on Thursday night in Game 4 of the Western Conference semifinals.
San Jose will host Game 5 on Saturday night with another chance to advance to hockey's final four for the second time in franchise history.
Franzen was originally credited with scoring the first goal 5:40 into the game, but a scoring change gave the goal to Todd Bertuzzi. That prevented Franzen from tying the NHL playoff record with four goals in a period.
Valtteri Filppula put Detroit ahead 5-0 late in the first period on a shot that went off San Jose defenseman Douglas Murray and effectively ended goalie Evgeni Nabokov's night.
Nabokov made just four saves in the first period and was replaced by Thomas Greiss, who let the second shot he faced get past him off Brian Rafalski's one-timer.
San Jose took advantage of a 5-on-3 power play when Dany Heatley scored with 48.5 seconds left in the second period to make it 6-1.
Jimmy Howard making 28 saves for Detroit.
Canadiens 3, Penguins 2

Maxime Talbot and Chris Kunitz scored 1:51 apart early in the first period to put Pittsburgh ahead. Pyatt had netted his first career playoff goal 2:34 in to put Montreal in front.

Game 5 is Saturday night in Pittsburgh.
