Mike Fisher scored just 28 seconds in, and Marian Hossa had a goal and an assist as the Ottawa Senators beat the New York Islanders, 3-1, last night in Uniondale, N.Y., to take a 3-1 lead in their first-round playoff series.

Anton Volchenkov also scored, and Patrick Lalime made 21 saves for the Senators. They will try to wrap up the best-of-seven Eastern Conference series at home Thursday night.

Adrian Aucoin scored for the Islanders, who have lost three straight after winning the opening game of the series.

The teams were coming off a double-overtime game Monday night that lasted 82 minutes 25 seconds. But Ottawa came out energized in the first period, scoring two quick goals and outshooting New York 15-6.

The Senators took a 1-0 lead when Fisher took a pass from Bryan Smolinski, carried in from the blue line and lifted the puck over Garth Snow's left shoulder and under the crossbar. Hossa also was credited with an assist.

Ottawa went up 2-0 on a fluke goal by Volchenkov at 4:12 of the first. Snow made the initial stop on Vaclav Varada's shot, and the rebound went to the left side of the net. Volchenkov got the puck and attempted a centering pass that deflected in off Snow's legs.

New York had a chance to cut the deficit with a five-on-three power play for 42 seconds bridging the first and second periods after penalties on Brian Pothier and Magnus Arvedson. But the Islanders didn't get a shot on goal.

Aucoin made it 2-1 at 2:48 of the second when he beat Lalime with a slap shot from the right point through a screen set up by Michael Peca. The goal, which came with the teams skating four-on-four, was unassisted.

Ottawa regained a two-goal lead at 8:01 of the second on the power play when Hossa took a shot in close that deflected in off Islanders defenseman Janne Niinimaa. It was the third playoff goal for Hossa, who set a team record with 45 during the regular season.

The Islanders thought they made it 3-2 with 7.2 seconds left, but Dave Scatchard hit the puck with his stick over the height of the crossbar, and it was ruled no goal by the officials on the ice. A video review did not overturn the call.

* AVALANCHE 3, WILD 1: Joe Sakic took the edge off another loud crowd with two goals in the game's first eight minutes, and Patrick Roy barely missed his second straight shutout while leading visiting Colorado.

The Avalanche, which finished the regular season by winning 25 of its final 37, leads the best-of-seven Western Conference quarterfinal series 3-1.

The Avalanche, which also got a goal from Dan Hinote, will try to end the series in Denver on Saturday. Marian Gaborik had the goal for Minnesota, making its postseason debut in the series.

For the first 30 minutes, Minnesota controlled the flow and spent most of its time in Colorado's zone yet still found itself trailing by two goals.

The Avalanche was outshot 14-7 midway through the second period and 25-21 for the game. But it simply beat the Wild at its own game -- with patient offense, solid defense and excellent goaltending. And Colorado has the advantage in that last category.

Roy was pelted early, but nothing the Wild put on net would go in until Gaborik's power-play goal with 2:40 remaining cut the lead to 2-1. That ended a string of almost 118 scoreless minutes for Minnesota.

Fernandez made 16 saves, his only blemish coming when Hinote -- left alone to Fernandez's right -- dumped in an easy rebound for the game's final goal.

* CANUCKS 4, BLUES 1: Martin Rucinsky had two goals and an assist as Vancouver rallied in St. Louis.

Dallas Drake and Chris Pronger scored in the second period after spotting the Canucks a goal. Rucinsky score twice in 1:37 late in the third.

St. Louis, which got a strong game from goalie Chris Osgood to offset a 33-20 shots deficit, can close out the series in Game 5 on Friday night in Vancouver. The Blues have won all six series in franchise history when taking a 3-1 lead.
