DENVER (AP) -Joe Pavelski scored 10:24 into overtime and Evgeni Nabokov stopped 33 shots, giving top-seeded San Jose a 2-1 victory over Colorado on Tuesday night and tying the series at two games apiece.
All four games have been decided by a goal, the last three going into overtime.
On his game-winner, Pavelski gathered up a loose puck deep in Colorado's zone and beat Craig Anderson with a shot into the right corner.
Dan Boyle gave the Sharks an early lead, knocking in a slap shot two days after scoring on his own goalie in overtime as he attempted to clear the puck.
The Avs countered with a second-period goal by Paul Stastny, his first of the series.
Game 5 is Thursday in San Jose.
Anderson has seen 148 shots over a span of three games. He had 43 saves Tuesday night.
PHILADELPHIA (AP) - Jeff Carter scored two goals and Danny Briere had one to end their playoff scoring droughts and lead Philadelphia over New Jersey and to a commanding 3-1 lead in their Eastern Conference playoff series.
Unlikely postseason star Daniel Carcillo scored his second goal in two games for the Flyers.
Game 5 is Thursday in New Jersey.
The Devils haven't won three straight games since they won five straight from Dec. 12 to 21.
The Flyers have won 17 of 19 playoff series when they hold a 3-1 lead. One of those blown leads came in 2000 in goalie Brian Boucher's rookie season. Ten years later and in his third stint with the organization, Boucher has them on the brink of advancing to the conference semifinal.
Martin Brodeur stopped 24 shots for the Devils.
Carter and Briere were held without a point in the first three games after combining for 114 this season. Carter led the Flyers in goals and Briere was third.
OTTAWA (AP) - Sidney Crosby had four points, including two of Pittsburgh's five goals in the second period, leading the Penguins to a 3-1 series lead.
Crosby assisted on Evgeni Malkin's power-play goal 11:50 in, the only score of the first period.
Crosby scored two of Pittsburgh's three goals in a 2:25 span early in the second. Matt Cooke scored 12 seconds after Crosby's first goal to make it 3-0, and the Penguins' 22-year-old captain added his fourth goal of the series at 6:12 to chase Brian Elliott.
Chris Kunitz had a goal and two assists and Maxime Talbot had a goal and an assist as the teams combined for eight goals in the second, one short of the NHL playoff record for goals in a period.
Jordan Staal scored in the third period and Marc-Andre Fleury made 26 saves for his third straight win.
Matt Cullen had a goal and two assists for Ottawa.
DETROIT (AP) - Jimmy Howard had a 29-save shutout and Henrik Zetterberg scored two goals to lead Detroit to the series-evening Game 4 victory.
Howard's saves included one without his helmet.
Phoenix will be at home Friday night, but has to return to Detroit for Game 6 on Sunday.
Zetterberg's first goal stood after a video review, which didn't help the Red Wings get a call changed in their favor earlier.
Replays appeared to show Valtteri Filppula got a puck past the goal line before it bounced on it, lighting the lamp. A video review upheld the on-ice decision to wave off the goal. It turned out to be moot.
Pavel Datsyuk also scored for Detroit.
Ilya Bryzgalov made 32 saves for the Coyotes.
NASHVILLE, Tenn. (AP) - David Legwand scored the go-ahead goal and had two assists, and Nashville took its first 2-1 lead ever in an opening-round series.
The Predators have never won more than two games in any of their first four playoff appearances.
Game 4 is here Thursday night.
Joel Ward and Shea Weber also scored for Nashville, and Martin Erat scored on a penalty shot late. The Predators more than made up for the absence of top goal scorer Patric Hornqvist, scratched for a second straight game with an injury.
Tomas Kopecky scored a power-play goal for Chicago.
The Blackhawks won a franchise-record 23 road games in earning the West's No. 2 seed. They are just 8-18 all-time when losing two of the first three games of a series.
Ward put Nashville up 1-0 with a backhander over Antti Niemi's leg off a rebound with 13 minutes gone. Kopecky tied it just 15 seconds later.
