Two seeded players lost, and two unseeded but dangerous competitors also fell Thursday in the quarterfinals of the $50,000 FSP Gold River Women's Challenger at the Gold River Racquet Club, the tournament reported.
Fourth-seeded Petra Rampre was stopped by the No. 5 seed, American Madison Brengle, 6-3, 6-3, while seventh-seeded Heidi El Tabakh of Canada lost to unseeded American Allie Will 3-6, 6-4, 6-4.
Brengle is the only seeded player remaining in the singles draw.
Alisa Kleybanova, a Russian formerly ranked No. 20 in the world before being diagnosed with Hodgkin's lymphoma in 2011, had breezed through qualifying and early rounds of the tournament but met her match in Croatia's Ivana Lisjak.
Pounding her heavy groundstrokes, Lisjak prevailed 0-6, 6-2, 7-6 (2), showing that her upset of No. 1 seed Maria Sanchez the previous evening was no fluke.
American Alexandra Stevenson, 32, who reached the Wimbledon semifinals as an 18-year-old, lost to 17-year-old Mayo Hibi, a diminutive Japanese amateur who already has won two pro titles, 6-2, 6-1.
In today's semifinals, Hibi will meet Will, while Lisjak takes on Brengle.
William Jessup hires Pleis as new AD
William Jessup announced it has hired Mitch Pleis, a former Stanford football player, as athletic director.
He will oversee the university's five men's and six women's teams.
Pleis, a Granite Bay resident, was a three-sport player at Del Valle High School in Lafayette, where he played football for his father, Wendell Pleis.
Pleis, 56, played tight end for two seasons (1977-78) at Stanford under head coach Bill Walsh and assistant George Seifert.
Pleis also has either played for or coached with Dennis Green, Jim Fassel, Rod Dowhower and Ray Handley, all of whom became NFL head coaches.
