Richards made it 2-0 just 30 seconds into the second. He took a pass from Derek Stepan at the blue line, skated into the high slot, and snapped in his 25th goal. New York took advantage of a penalty for too many men on the ice called against Montreal in the final minute of the first period.
Del Zotto scored a rare power-play goal 8:17 into the third, firing a shot that squeezed past Price. He made it 4-0 with 3:02 remaining, scoring his 10th of the season. Gaborik and Richards earned assists on the final goal.
Although their power play came in ranked third from the bottom in the NHL at 14.7 percent, the Rangers are remarkably efficient when they cash in — going 24-1-4 in games in which they score a power-play goal.
The Rangers are 4 for 9 on the power play in the past two games.
"With the skill we have, we're going to be able to score goals," Del Zotto said. "You see just the way we're moving the puck, we're moving bodies.
"We're not predictable. Teams don't know exactly where we're going to be attacking from or what's going to be happening. That's what makes us deadly right now."
