The world number one tennis player, Martina Hingis, is through to the semi-finals of the Rosmalen grass court tournament in Holland, after her quarter-final opponent, Cara Black of Zimbabwe, withdrew with flu.

Hingis player has spent only 36 minutes on the court in the tournament so far.

After being given a first-round bye, she lost only two games in her second round match against Canada's Jana Nejedly.

Her semi-final opponent is the American, Jennifer Capriati, who defeated the Swiss number two, Patty Schnyder, in straight sets on Thursday.

Hingis and her closest rival in the world rankings, Lindsay Davenport, have become the first to qualify for the Chase Championships in New York at the end of the season. The tournament in November features the top 16 women's singles players.

In the men's game, Switzerland's Ivo Heuberger, has narrowly missed qualifying for Wimbledon, which starts next Monday. In the last round of the qualifying games, Heuberger was beaten by South Africa's Justin Bower in a gruelling five set match.
