IPFW (12-3, 2-1 Summit League) in the victory out-hit South Dakota .241 to .216, including having a match-best .357 attack percentage in the opening game.
South Dakota outside attacker Kendall Kritenbrink in the loss led all players with 22 kills.
IPFW libero Tessa McGill finished with a match-high 20 kills.

With this victory, IPFW moves into a three-way tie for second place in the Summit Leauge and a half-match behind first-place IUPUI — a team the Mastodons defeated Tuesday.
