"We came out on fire," Lewis said. "I served 10 straight points. The intensity was really high. We had a very balanced attack."
The Crimson had eight service aces in the match, which lasted an hour.
Mager had another quality match with 12 blocks, 10 kills and a .769 kill percentage.
Lewis contributed seven kills and eight digs and Guilianelli added ten kills and 12 blocks.
The Crimson's next contest comes Wednesday when the team travels to Hanover, N.H., for an exhibition with Dartmouth.
That match will be a warm-up for upcoming matches against Princeton and Rutgers-Newark.
"Princeton is our biggest rival," Lewis said. "It's a match we've been working for all season. We're going to be working pretty hard in practice this week."
"Last year they were in the Final Four," he added. "So they are perennially strong. They graduated four, so this is our best chance to take them down."
The Crimson will face Princeton and Rutgers-Newark this weekend at the Malkin Athletic Center.
