Palo Alto grads Colleen Fotsch and Liv Jensen helped California open a lead at the Pac-10 women's swimming championships in Federal Way, Wash., after two relay events.
The former Vikings swam the final two legs of the 200 medley relay, with Jensen anchoring the Bears to a 1:35.62 clocking, an NCAA automatic qualifying time.
Stanford's team of Betsy Webb, Liz Smith, Felicia Lee and Sam Woodward raced 1:38.61 to finish fourth.
The meet continues Thursday with preliminaries and finals in the 500 free, 200 IM, 50 free and the 1-meter diving event.
The men's 3-meter diving event will also be contested.
Stanford freshman Andie Taylor and senior Kelsey Ditto are both ranked among the conference's top 10 in the 500 free, while the Cardinal have three ranked among the top seven in the 200 IM with freshmen Maya DiRado and Lee plus Smith, a senior.
Webb and Kate Dwelley are seeded third and fourth in the 50 free, just behind No. 2 seed Jensen.
Andi Murez, DiRado, Taylor and Dwelley comprised Stanford's 800 free relay, which was timed in 7:02.19 for a second-place finish.
In the men's 1-meter diving competition, Dhruv Tyagi finished fifth as Stanford's top diver. Brent Eischsenseer was seventh.
