Freshman Jordan Raney scored twice and the top-ranked Stanford women's water polo team beat host No. 4 California, 7-3, in the Mountain Pacific Sports Federation regular season finale for both teams on Thursday.
Some dominant defense and a decisive third quarter proved to be the winning recipe for the Cardinal in its annual Big Splash against the Golden Bears.
The win, Stanford's 39th consecutive regular-season MPSF victory, secured the Cardinal's sixth consecutive unblemished league campaign.
Stanford (6-0 MPSF, 21-1 overall) takes the No. 1 seed into next weekend's conference tournament in Tempe, Ariz.
The victory also continued the Cardinal's run against its rival. Stanford has won 41 consecutive games against the Golden Bears dating to 2000.
Stanford scored four times in a decisive run in the third period to help put the game out of Cal's reach. The Bears were within 3-2 at the half.
Raney, who is making a bid for Freshman of the Year, scored to make it 6-2 in the third, all but clinching it.
Overall, the Golden Bears were unsuccessful on each of their nine 6-on-5 opportunities and were held to a season-low three goals.
Gurpreet Sohi started the four-goal run at 4:50 in the third when she crept closer to the center of the pool and converted a cross-cage shot from a difficult angle to put Stanford up 4-2.
The Cardinal scored on three consecutive possessions beginning at 2:17 in the third when Roser Tarrago was whistled for an exclusion.
A quick shot from Jamie Neushul at the start of the 6-on-5 for the Cardinal extended Stanford's advantage to 5-2.
On Stanford's next possession, Raney one-timed a perfect pass from Sohi low and left past Cal's Madeline Trabucco.
Junior goalkeeper Gabby Stone recorded eight saves in the contest.
Cal's three goals scored not only tied a season-low for the Golden Bears, but were also the fewest Stanford has allowed in an MPSF match since UCLA scored one on April 6, 2013.
Stanford, the defending MPSF tournament champion, has a bye into the semifinals and will meet the winner of No. 4 seed California and No. 5 seed Arizona State on Saturday at 2:30 p.m.
