Quick clears out of the defensive zone and good forechecking prevented UMD from testing Israel more than three or four times on those five opportunities.
Senior Brian Farrell scored an unassisted goal right at the end of the fourth penalty kill, 11:16 into the second period. Farrell skated into the UMD zone and backhanded the puck through Butler's legs after a nifty head fake to extend Harvard's lead to 5-1.
Maguire's first goal of the season, the team's fourth power play goal, extended the lead to 6-1, as his point shot deflected up into the air off Butler before trickling behind him into the net.
"I caught the goalie off guard," Maguire said. "It wasn't a glorious goal, but I'll take it."
The Bulldogs scored two quickies in a span of 38 seconds near the end of the second period, but Harvard countered back early in the third off two goals by junior Cory Gustafson.
Gustafson's two tallies initiated replacement netminder Niklas Axelsson and made the score 8-3, ending all realistic hopes of a UMD comeback.
Martins scored his second goal of the game and the team's fifth power play goal to make the score 9-3 before the Bulldogs scored the final goal.
"Most of my goals come off power plays," Martins said. "Thankfully, the power play was working Saturday night."
The physical aspect of the game also worked well for the Crimson, as Harvard gave UMD some of its own medicine. There was a lot of rough stuff, with a half-dozen pairs of coincidental minors being assessed.
The most vicious play of the game came after the final buzzer, when a UMD goon almost took the head off freshman Stuart Swenson (a St. Cloud, Minn. native) with a brutal slash. Swenson had finished a hard check before the final buzzer, but was luckily able to escape without an injury.
Harvard won't be sending any Christmas cards to the UMD players, but the Crimson will take the two points nevertheless.
"Coming off the loss, this win was huge," Martins said. "We played really well. If we play as intensely in the ECAC as we did on Saturday, we can dominate our league."
