LONDON — Marathon man John Isner is at it again at Wimbledon.
The winner of the longest match in tennis history found himself involved in another never-ending one at the All England Club, tied with reigning U.S. Open champion Marin Cilic at 10-all in the fifth set when their third-round contest was suspended because of darkness Friday night.
They were scheduled to resume Saturday.
In the first round at Wimbledon in 2010, Isner edged Nicolas Mahut 70-68 in the fifth set of a match that lasted 11 hours, 5 minutes, spread over three days.
