Completing a trio of top 20 players who flopped on day one, Germany's Rainer Schuttler, the man who made the second biggest improvement of any player on the ATP Tour last year, suffered his fourth first round defeat out of five.

Philippoussis, the fifth-seeded Wimbledon runner-up from Australia, paid the penalty for missing a set point in the second set and was beaten 6-2, 7-6 by Olivier Rochus, the world number 61 from Belgium.

The 6ft 5ins Philippoussis is fully one foot taller than Rochus and had a great advantage in power, but was unable to impose it upon the shortest man on the tour.

Rochus returned Philippoussis' famous serve excellently in the first set, but the second depended on a tight tie-break in which the Aussie seemed to be escaping from trouble when he led by seven points to six.

But when he advanced to the net behind a faded forehand Rochus covered the width of the court and struck a wonderful backhand pass cross-court.

Three points later Philippoussis mistimed an ambitious backhand to concede a mini-break and Rochus closed it out with a tidy second serve which Philippoussis failed to return.

"It's just great," said Rochus.

"I knew I had to make him run. He has a very good serve and I had to return as many balls as possible, try to get into the rallies and make him move. It worked."

Henman went from defeating the world number one Roger Federer in his last tournament to losing 6-4, 3-6, 7-6 to a man ranked 149 in the world, Tomas Zib.

The British number one tried to impose an attacking game at every opportunity, but found the Czech qualifier resilient in slowish night conditions, often making some fine passes.

The key moments came after Henman had broken serve to lead 2-1 in the final set, but was unable to consolidate. After that he played far more pragmatically and Zib became encouraged.

By the tie-breaker Henman was under the greater pressure and mini-breaks in the third and the seventh points were enough to see the man from Prague go through.
