IF HE was paid by the point, big-serving John Isner would be the richest man in world tennis.
The American, who has made a habit of being involved in marathon matches at Grand Slams, was beaten in the third round at Roland Garros by 35-year-old German Tommy Haas, 5-7 6-7 6-4 7-6 8-10.
Incredibly, that match followed on the heels of his second round epic against countryman Ryan Harrison when Isner came from two sets down to win 5-7 6-7 6-2 6-1 8-6.
The big leftie was also involved in a marathon in Paris last year - beaten 7-6 4-6 4-6 6-3 18-16 in the second round by Paul-Henri Matthieu.
But even that paled in comparison with Isner's first-round match against Frenchman Nicholas Mahut in the first round at Wimbledon in 2010, the longest match played in men's tennis.
The contest was played over three days and took more than 11 hours on court, Isner eventually winning 6-4 3-6 6-7 7-6 70-68.
Haas will now meet Russian Mikhail Youzhny in the round of 16.
Meanwhile Australia's last hope, No.9 seed Sam Stosur, was beaten 3-6 6-3 6-4 in the third round by Serbia's Jelena Jankovic.
