BIRMINGHAM, England -- Misaki Doi of Japan defeated Foretz Gacon of France 7-5, 6-4 to reach her first WTA quarterfinals at the Aegon Classic.
Doi will play Jelena Jankovic on Saturday after rain halted play.
Zheng led 6-3, 5-3, but rain intervened. There was a 42-minute delay at 5-4 before three more minutes of play, then a nine-minute delay before they played another eight minutes.
Zheng dropped her serve despite having recovered from 0-40 and reaching deuce. Vinci held serve for 6-5 before the rain came again and washed out play for good.
