No. 3 seed Cal Poly, which rallied to beat Hawaii in five sets at SimpliFi Arena at Stan Sheriff Center three weeks ago, advanced to play the Rainbow Wahine on Friday after scoring a reverse sweep of UC Davis, 19-25, 15-25, 25-19, 25-22, 15-13 in the nightcap Wednesday at Walter Pyramid.

Tommi Stockham had a team-high 16 kills and senior libero Jolei Akima, a Kamehameha alumna, finished with a match-high 21 digs and seven assists to help the Mustangs (21-10) advance.

Reese Diersbock, a Le Jardin alumna who made the All-Big West Freshman Team, had a match-high 17 kills and two blocks for the Aggies (13-16), who led 2-0 with seven aces and nine blocks over the first two sets.

Hawaii split its matches against Cal Poly this season, winning on the road in four.
