Crosby made it 2-0 at 14:09 of the first, redirecting Matt Grzelcyk’s slap shot from the left point past Rittich. Crosby has 51 points (13 goals, 38 assists) in 49 games this season.
Malkin extended the lead to 3-0 at 8:26 of the second period, scoring five-hole from the right circle off a backhand cross-slot pass from Philip Tomasino.
Adrian Kempe cut it to 3-1 at 16:02 with a one-timer from the right circle off a pass from Kopitar during a 5-on-3 power play.
Cody Glass responded to make it 4-1 at 19:00. He tapped in a centering pass from Hayes from the edge of the crease.
“It was definitely not our game tonight from top to bottom,” Kopitar said. “Didn’t get anything going, and even when we did with the power-play goal, they come right back and score the fourth one, which turned out to be, obviously, a big goal. It’s a lot different being down two going into the third versus three.”
