After falling 6-2 in the opener CBU came back to take the late game 11-6.
A five run second inning was too much for the Lancers to overcome in the opener as CBU managed just two runs in the contest.
Five singles, a hit batter and a passed ball allowed the Sea Warriors to strike first in the early game.
The Lancers got on the board in the fourth scoring a pair of runs on a single from April Vasquez and a sacrifice fly from Savannah Miller. That was all the offense CBU could muster, however, as HPU's Melissa Kirby got the complete game win.
CBU left five runners on base in the game.
The early runs continued for HPU as the Sea Warriors scored two runs in each of the first two frames in the late game.
The Lancers stayed close, though, behind a two-run single from Mara Rodriguez in the second and then took their first lead of the day with a big rally in the third.
Sloan McHann kicked the rally off with an RBI double and then Miller and Ashley DeVaere each singled in runs to put the Lancers up 5-4. Jordan Mowatt continued the hit parade with another RBI single and Rodriguez capped the scoring with a sacrifice fly.
McHann would tack on another in the fourth with her fourth homer of the season. McHann was 3 for 5 with three RBI in the game.
Two more runs in the seventh sealed the deal on the five-run Lancer win. CBU posted 18 hits in the offensive outburst.
Jessica Avila came back to get the win in the late game moving to 5-4 on the season.
The split moves the Lancers to 9-8 overall, 3-5 PacWest. HPU moves to 8-6, 1-3.
