Niagara was swept at Wayne State earlier this season and last weekend returned the favor in western New York as the Purple Eagles put two wins on the board against the Warriors.
Friday night, Sam Poyton had a goal and an assist for WSU and Melissa Boal also scored in a 3-2 loss. Val Turcotte made 20 saves while Allison Rutledge stopped 39 for NU.
Saturday night, Chelsea Donovan's third goal of the weekend, 4:23 into overtime, gave Niagara the 2-1 win.
Sarah Campbell (pictured) netted WSU's goal midway through the third period.
Tiffany Thompson finished with 25 saves and Rutledge had 38.
Wayne State finishes the season 14-15-5 overall and 6-4-2 in the CHA.
The two teams rematch Thursday in the CHA Tournament semifinals at the State Fairgrounds Coliseum at 8:05 p.m. WSU is the No. 2 seed and Niagara is seeded third. Mercyhurst finished first in the CHA and first-year Robert Morris dead last.
