Brian Boyle knows he's in danger of being left out just as the Rangers are starting to play their best hockey.

"I know what I should be and what I'm supposed to be on this team," Boyle said. "I'm going to make sure that's where I'm going to be."

Boyle scored the winner in a 4-1 victory over the Capitals on Sunday afternoon at Verizon Center, his first goal in 20 games this season coming after he was a healthy scratch in Friday's 3-2 loss to the Senators.

The Rangers (13-9-2) reached the midway point of this lockout-shortened season with a sustained three-zone effort, offsetting a rough start for their fifth win in six games as they began a season-high four-game road trip.

Backup goalie Marty Biron made 28 saves in his fourth start, recovering after whiffing on rookie defenseman Steve Oleksy's shot from the right point at 2:16 of the first period.

But Biron stopped Joel Ward's point-blank shot as the Rangers killed off a five-on-three power play for the Capitals (10-13-1) after Darroll Powe tripped Ward at 18:50 of the second period with Boyle already in the box.

"I think we're beginning to sort ourselves out as far as how we have to play and doing it a little bit more consistently," coach John Tortorella said.
