Freshman Tammy Butler hauled in a game-high 11 rebounds, but 10 of those 11 came in the first-half.
The second half belonged to Brown's 6'5" freshman center Martina Jerant.
Jerant, who had sat out most of the first half with foul trouble, returned to haunt the Crimson. She grabbed six boards and tallied 17 points down the stretch as Brown shot a scorching 64 percent from the field.
Jerant almost single-handedly blew the game wide open.
When Flandermeyer took a break at 9:55 with Brown up, 50-47, Jerant stepped up her game and scored six straight points in two minutes.
Jerant's heroics swung the momentum in Brown's favor, and Harvard was unable to recover.
The problem was compounded by Delaney Smith's decision not to call a time out until the game was out of reach.
With 4:15 remaining, Brown commanded a ten point lead that it would never relinquish.
