DETROIT - Darren Helm scored with 1:27 left in the third period, lifting Detroit to an elimination-avoiding win over San Jose in Game 4 of the Western Conference semifinal series.
The Sharks will take their 3-1 series lead back home with a chance to advance on Sunday night to the NHL's final four. Detroit is trying to become the fourth NHL team to win a series after trailing 3-0.
Veteran defenseman Nicklas Lidstrom scored twice in the first period to help the Red Wings take a three-goal lead that slipped away.
Logan Couture had a goal 15 seconds after Lidstrom's second, Dan Boyle scored midway through the middle period to pull San Jose within 3-2, and Dany Heatley tied it early in the third.
Helm put Detroit back ahead for good, scoring from the left circle off a cross-ice pass from Patrick Eaves.
Todd Bertuzzi also scored for Detroit, and Jimmy H oward made 25 saves for the win.
BRUINS 5, FLYERS 1
BOSTON - Milan Lucic scored twice, Johnny Boychuk got the go-ahead goal, and the Boston Bruins stopped any chance of another historic comeback by the Flyers with a win Friday night that completed a sweep of the Eastern Conference semifinal series.
In this round last year against Philadelphia, the Bruins became just the third NHL team to lose a series after winning the first three games. Boston even held a 3-0 lead at home in Game 7 before the Flyers rallied again for a 4-3 victory.
Kris Versteeg lifted Philadelphia into a 1-1 tie on Friday at 13:22 of the second period after Lucic scored at 12:02 of the first.
Boychuk put Boston ahead at 2:42 of the third, Lucic connected again at 15:03, and Brad Marchand and Daniel Paille added empty-net goals.
