Senior Chloe Lippert, who narrowly missed on a couple earlier scoring opportunities, finally got one past the keeper early in the 31' that made it 3-0. It was her team-leading fourth goal this season.
Waldorf got on the board early in the 88' with an own goal that deflected off the Beavers.
The Beavers put the pressure on the Warriors throughout the match, finishing with 15 total shots compared to only eight for Waldorf. King, Rowedder and Haley led the way with three shots apiece for BVU with Lippert and Alyssa Cathcart adding two.
Trisha Westphal made five saves while going the distance in goal.
Buena Vista improves to 3-0-1 overall and will now go on the road for the first time this season when it travels to Maranatha Baptist University on Sept. 12 for a 2 p.m. kickoff.
