Wimbledon test matches set for TV

ESPN Classic will air live coverage of the May 17 exhibition matches under Wimbledon's new Centre Court roof.

Past Wimbledon champions -- and married couple -- Andre Agassi and Steffi Graf are scheduled to play, as are Tim Henman and Kim Clijsters. The event is being called "A Centre Court Celebration" and will be a test of the All England Club's new retractable roof and ventilation system.

ESPN Classic will air 3½ hours of the British Broadcasting Corp. feed, starting at 9:30 a.m. ET.

The schedule includes a men's singles match, a women's singles match and a mixed doubles match.

Wimbledon begins June 22.
