Without watching a minute of action, it was easy to tell which New York team came out on top in the first half of a home-and-home series between the Islanders and Rangers.

All it took was a glimpse at the postgame reactions.

While the Islanders celebrated a team effort that produced a 2-1 road win on Wednesday night, Rangers coach John Tortorella unleashed an expletive-filled tirade after his offensively challenged club dropped its fifth straight (0-3-2).

The Rangers fell behind 1-0 in the first period and were outshot 10-3 by the Islanders, who were coming off a 7-1 loss at home to Florida on Monday night. The teams will meet again Thursday night on Long Island.

"The thing that's unacceptable about tonight's game, and we're trying to stay positive around here, trying to work our way through it, but when we play like that for 20 minutes in a game like this in a back-to-back situation, it's unacceptable," Tortorella said. "There has to be something done, and we'll see along the way before (Thursday) night's game. We'll see where we go with them.

"It's just simply unacceptable how we started that game. I wish I could give you an explanation about it. I can't."

Tortorella then smacked a chair and stormed out of the interview room.

Dwayne Roloson made 25 saves, and Jon Sim and Blake Comeau scored for the Islanders, who won one of six meetings between the rivals last season. They are already 2-0 against the Rangers this season.

The steady Roloson was 55 seconds away from his first shutout in a year when Enver Lisin brought the Rangers within 2-1. Roloson has gone 71 games since he blanked Vancouver while with Edmonton on Dec. 13, 2008.

"I don't care if we win 10-9 or 11-10 or whatever, as long as we win the hockey game," Roloson said. "We were doing the little things that we had to do to win in the first period and we continued that all the way through for 60 minutes."

He was helped by the Rangers, who scored two goals or fewer for the seventh straight game and for the 17th time in 21 contests.

Sim scored in the second period, and Comeau provided much-needed insurance when he made it 2-0 with 3:10 left in the game.

Roloson was pulled Monday after allowing five goals on 23 shots and suggested the Islanders might have been flat because of the anticipated series with the Rangers. The Islanders are 4-6 in their last 10.

"It could've been a possibility, but fortunately for us we came back and bounced back," he said.

Henrik Lundqvist made 26 saves for the Rangers, who are 1-6-2 in their past nine while scoring only 15 goals.
