Clarkson added its second goal off the stick of right winger Jay Latulippe at 16:55 in the third, and Latulippe added empty-net insurance with 14 seconds to go.

All in all, though, it wasn’t the Crimson’s defense or its goaltending that had Harvard on the sour side of a 3-0 decision, but rather the team’s inability to convert on special teams.

“You’re not going to win many games when you don’t score a goal,” Mazzoleni said.

Harvard 3, St. Lawrence 0

Grumet-Morris made 26 saves to record the shutout and sophomore winger Charlie Johnson and senior winger Tyler Kolarik assisted on each other’s goals as Harvard posted a 3-0 win over St. Lawrence (3-10-3, 2-5-0) Friday night for its third consecutive win.

Johnson finally broke through with the game-winner with one second left on a carry-over power play 14 seconds into the second period after the Crimson let 14 shots fly at McKenna without scoring in the first.

Johnson got his stick on a slapshot from senior defenseman Dave McCulloch and deflected it by McKenna. Kolarik also assisted on the play.

The goal was Johnson’s third of the season. All three have come on the power play. Harvard has scored five power-play goals this season.

Meanwhile, Grumet-Morris kept St. Lawrence off the score sheet even though the Saints found room to operate behind his net in the first period and then tested him several times in the second.

Grumet-Morris was forced to slide across his crease to stop a one-timer from Kyle Rank on a St. Lawrence power play early in the second and made a big save after a Harvard giveaway just a few minutes later.

“I thought it was [Grumet-Morris’] best game of the year,” Mazzoleni said. “He was in total command of the position.”

The Crimson has allowed just two power-play goals in its last five games. Its opponents are 2-24 on the power play during that stretch.

The shutout was Harvard’s first since a 5-0 blanking of the Saints on March 1 of last season.

The Crimson has outscored St. Lawrence 14-1 in the teams’ last three meetings.

Senior winger Dennis Packard gave Harvard a 2-0 lead at the 13:44 mark of the second off an assist from classmate and linemate Tim Pettit.
