MANHATTAN BEACH, Calif., Aug. 9 (UPI) -- The 21-match winning streak of Serena Williams came to a stunning end Friday.
No. 12 seed Chanda Rubin shocked the world No. 1, recording a 6-2, 4-6, 7-5 triumph to reach the semifinals of the J.P. Morgan Chase Open.
During her run, Williams captured the Rome, French Open and Wimbledon titles, dropping a mere three sets along the way.
Rubin avenged a straight-sets loss to Williams in the round of 16 at the All-England Club.
The 20-year-old Williams, who also captured titles at Scottsdale and Miami earlier this year, had not been beaten since falling to Belgium's Justine Henin in the final of the Berlin claycourt event.
Williams won here in 1999 and 2000 but squandered seven match points in a quarterfinal loss to Monica Seles a year ago.
Rubin will face fourth seed Jelena Dokic in Saturday's semifinals after the Yugoslavian eased past Italy's Rita Grande, 6-4, 6-1.
In Friday's other quarterfinals, second seed Jennifer Capriati took on Ai Sugiyama of Japan and No. 3 Lindsay Davenport met Eleni Daniilidou of Greece.
