"We came ready to play, but we were not finishing," said Harvard co-captain Justin Micomonaco. "With everyone switching positions, our block is significantly weaker."
Stevenson led all players with 16 kills, while Bookman, returning from a back injury, recorded a game-high 33 assists.
Harvard will next take to the road to face Sacred Heart on Wednesday. The Crimson then returns home for a divisional homestand against East Stroudsberg and Queens.
