KIKI KO FOR CHAMP MUG

DEFENDING champion Garbine Muguruza crashed out of the French Open to home favourite Kiki Mladenovic – then blasted the Paris crowd.

And defeats for Venus Williams, Sam Stosur and Svetlana Kuznetsova means no Grand Slam winners have reached the quarter-finals.

Spaniard Muguruza lost 6-1 3-6 6-3 on a noisy Court Suzanne Lenglen despite the French No.1’s 16 double faults.

Breaking down in tears and briefly leaving her press conference, Muguruza said: “It’s a very painful defeat. I think the audience was really tough. Sometimes they should be a little bit more respectful.”

Mladenovic (above) now faces Switzerland’s Timea Bacsinszky, who beat Williams 5-7 6-2 6-1. Caroline Wozniacki knocked out 2009 champion Kutznetsova 6-1 4-6 6-2.
