NEW YORK — Derick Brassard and John Moore had no way of knowing just how well their debut with the New York Rangers would go.

They started the day at practice with the Columbus Blue Jackets and ended it as key offensive forces in the Rangers’ surprising 6-1 rout of the Pittsburgh Penguins on Wednesday night.

Brassard and Moore arrived just 15 minutes before pregame warm-ups, following a trade that sent star forward Marian Gaborik from the Rangers to the Blue Jackets.

Throw in Ryane Clowe, acquired Tuesday night in a deal with San Jose, and the newcomers were the driving force in New York’s highest-scoring game of the season.

“I shook their hands and said, `Go have fun,”’ Rangers coach John Tortorella said. “Everybody is coming up to introduce themselves, and they’re trying to get their (stuff) on.”

Clowe had his first two goals of the season and an assist, Brassard had a goal and three assists, and Moore also scored his first of the season to power the Rangers to victory. Brian Boyle, not a newcomer, also broke out with a goal and three assists.

The Rangers scored three goals in the first period and never looked back. New York was also buoyed by a season-high three power-play goals.

Henrik Lundqvist got a chance to relax a bit, making 26 saves and earning his 268th win, the second most in Rangers history.

Pascal Dupuis scored in the second period for the Penguins, who lost for the second consecutive night after 15 consecutive victories.

Marc-Andre Fleury, who replaced shelled starter Tomas Vokoun in the Penguins’ 4-1 home loss to Buffalo on Tuesday, played the duration on Wednesday and made 33 saves.
