Tickets for Wimbledon test matches sell out quick

Tickets for the exhibition matches to be played under Wimbledon's new Centre Court roof sold out in five minutes Thursday.

The event, featuring former Wimbledon champions Andre Agassi and Steffi Graf, as well as Kim Clijsters and Tim Henman, is to be played on May 17 in front of 15,000 spectators.

"The demand for tickets was truly exceptional and we are delighted to have a capacity Centre Court crowd for a great day," said Ian Ritchie, the chief executive of the All England Club.

The event _ dubbed "A Centre Court Celebration" _ is designed to test the new roof and air management system with live matches in front of a capacity crowd.

The program will feature a men's singles, a women's singles and a mixed doubles match. The matches will be played in a pro-set format _ the first to eight games, with a tiebreaker at 8-8.

The new sliding roof will help alleviate Wimbledon's perennial rain delays.

This year's Wimbledon tournament will be held June 22-July 5.
