Stosur through to quarters

AUSTRALIA'S US Open champion Samantha Stosur has progressed to the quarter-finals of the French Open with a 7-5, 6-4 victory over American teenager Sloane Stephens in Paris.

Stosur took a little longer than anticipated to reach the final eight, with the match moved to Court One as two men's fourth-round ties ran longer than anticipated on Centre Court.

Stosur served for victory at 5-3 but produced a double-fault to give away three break points, perhaps disturbed by having to replay one point after a pigeon swooped along the top of the net during play.

Stephens, 19, broke the sixth seed, but Stosur broke straight back to love and will now play Slovakian Dominika Cibulkova, who pulled off a major upset when she knocked out world number one Victoria Azarenka.

The 15th seed won 6-2, 7-6 (7-4) against the Australian Open champion, who had been expected to coast past Cibulkova, having beaten her seven times out of eight previously.
