After a shaky first half, Bishop hit a pair of big 3-pointers and 3-of-4 free throws in the second half including the game clincher with 6.2 seconds remaining.

The Warriors took their first lead of the period at 45-44 with 41 seconds showing on a putback by Wood.
Ripley responded with two free throws from Sarah Williams 13 seconds later for a 46-45 advantage but would not score again. A pair of buckets by Burger - one on a putback of her owned missed free throw - and the free throw by Bishop closed out the scoring.
The Vikings managed to keep the 6-foot Wood in check most of the game.
"They were doing a lot of different things, really mixing it up," Garretson said. "That was the main thing."
One thing common to every defense that Ripley threw against Riverside was that it was aimed at keeping the ball out of Wood's hands.
When she did get her hands on it good things happened for the Warriors.
Wood hit 5-of-9 shots from the floor and 6-of-8 from the foul line. She ended up with a triple-double of 16 points, 12 rebounds and 10 blocks before fouling out with 21.9 seconds remaining.
