The Crimson notched its other two goals in the second half.
Freshman Beth Morgan scored unassisted from 30 yards out when the Crusaders goalie misplayed her high, arcing shot.
The final goal was scored at the 14:34 mark when sophomore midfielder Laura Flynn's cross was tapped in by junior forward Kristy Gaschler for the easy goal.
The strong play of the Crimson bench was also notable.
Not only did Flynn and Gaschler combine for a score, but there was virtually no dropoff in the quality of play as Wheaton substituted his first-stringers.
"The bench almost outscored the starters," Wheaton said. "They certainly had a lot of chances."
The Crimson's depth has become one of the strengths of the team, affording Wheaton the luxury of being able to rest his starters.
