Lehigh scored early and often, opening the game up early in the first half.
With the score tied 4-4 less than five minutes in, Lehigh's Mackey McKnight dropped in a layup that started a 44-10 run the rest of the half. That 34-point halftime lead held up despite William & Mary outscoring Lehigh 43-34 in the second half.
Brandon Britt scored 12 points and Marcus Thornton had 11 for the Tribe (0-4), who have lost both of their games in the early-season tournament.
