All told, he gathered 22 stops in the game.
Harvard also controlled the midfield, with Prusmack dominating the faceoff until exiting late in the second half with a bruised knee.
It would be remiss not to acknowledge the spectacular play of Porter. The attacker slashed through Eagles for a hat trick of unassisted goals.
Junior Marty Dolan also netted two goals during the game.
Unable to Maintain Intensity
The glaring flaw for the Harvard squad was its inability to maintain its intensity in the late stages of the game.
BC was able to pour in three late goals against a sluggish Harvard team in the fourth quarter.
Against an inferior squad such as BC, Harvard can afford 15 minute lapses. However, in Ivy League competition, the Crimson will have a tougher time if it doesn't play 60 minutes of hard lacrosse.
The Crimson next heads to West Point to clash with Army this Saturday. This will be real test of the newly energized Crimson offense.
Army has already beaten the Cornell squad which swamped Harvard only a few days ago.
A big win in New York would bode well for the challenging Ivy League schedule ahead.
