Images from Day 10

The 18-year-old Vaidisova, who burst into the limelight by reaching the semi-finals here last year and was seeded sixth, had her chances and survived four match points before bowing out by netting a forehand.

Jankovic, 22, who established herself as a top contender by winning three titles this year to break into the top five, will meet world number one and defending champion Justine Henin for a place in the final.
