Shawna Castle netted 16 points for the Pios, while teammates Allison Farr and Crystal Castle scored 14 and 10.

Pacific would work the deficit back to 28-18 on two Arnall free throws at the 5:51 mark, but the Pioneers would use a quick 5-0 burst to squelch a Boxer rally. Terhar buried a mid-range jumper for the Boxers at 1:37 to cut the lead to 13, but the only scoring Pacific saw after the Terhar bucket was an Arnall free throw as the Pioneers took a 42-25 lead into halftime.
The Boxers looked like they would make a charge for the lead in the second half as Jackie Olson converted two lay-ups to cut the Pioneer lead to 48-34 with 14:28 left in the stanza. Lewis and Clark would answer with an 8-0 run, fueled by Moon's three-ball with 5:32 left in the contest.
Arnall connected on six of her 20 points in the final five minutes, connecting on a lay-up and four free throws. Lewis and Clark defense stiffened and only allowed two more points afterward on a Ella Morris jumper with 0:52 left. Pacific outscored Lewis and Clark in the second half, 27-25.
