Williams upset by disappointing display

Serena Williams tonight struggled to comprehend how she could have played so badly after becoming the second modern great to fall to Samantha Stosur at this year’s French Open.

Seventh seed Stosur, who on Monday became the first woman to beat Justine Henin at Roland Garros for six years, held off a tremendous fightback by Williams - who had match point – to win 6-2 6-7 (2/7) 8-6 and reach her second successive Roland Garros semi-final.
