The Knights finally took advantage of a power-play chance of their own, knotting the score at one at 17:41 in the second.

Burton won the faceoff against senior Alex Fallstrom, and sent the puck to defenseman Andrew Himelson. The senior then fired a slap shot from the left point through traffic, which was ultimately deflected by Burton into the top left corner of the Harvard net.

Nine seconds later, Clarkson took the lead with another goal. Zarbo skated across the blue line on the left and sent a wrist shot through the Crimson defense and the five-hole of Girard to make it 2-1 Knights entering the final frame.

“The second one hurt I think because we were just coming off the first one and I wouldn’t call that necessarily a great scoring chance,” Donato said. “We’d probably like that one back from a goaltending perspective.”

Zarbo continued the scoring in the third period with his second of the night, burying a rebound off a shot from defenseman Paul Geiger from the middle of the blue line. Joe’s brother Matt also was credited with an assist.

Adam Pawlick added another goal for the Knights before Zarbo made it 5-1 with his empty-net goal.

“We have to do things in the offensive zone to take some pressure off the defense and goaltending,” Donato said. “That to me is more the solution for us – to become more dangerous both on the power play and five-on-five.”
