Cornerstone (12-6, 6-4 WHAC) jumped out to an early 8-4 lead before Rachael Kruse and Chelsea Carradine led the Warriors on a 10-0 run to take what would be their largest lead of the game.
The Golden Eagles would answer with a big run of their own to retake the lead and would go into halftime with a 34-26 advantage.
Cornerstone maintained a comfortable lead for most of the second half, going up by as much as 13 midway through the period. Indiana Tech chipped away at the deficit and got within six after Sabine Filippovica knocked down a pair of free throws with just over a minute to play, but Cornerstone made the most of their trips to the charity stripe in the closing seconds to hold off the Warriors.
Carradine paced the team with 12 points, five assists, and four rebounds. Filippovica added a season-high 11 points and five boards off the bench, while Kruse and Ulyssia Richmond finished with 10 points apiece.
The Warriors will travel to third-ranked Davenport Saturday at 1 p.m.
