Wimbledon, London: Marathon man John Isner faded at the finish of another five-setter Monday at Wimbledon.
The highest-ranked American failed to convert a match point in the fourth set and lost in the first round to Alejandro Falla of Colombia, 6-4, 6-7 (7), 3-6, 7-6 (7), 7-5.
Isner is best known for winning the longest match in tennis history two years ago in the first round at Wimbledon, when he edged Nicolas Mahut 70-68 in the fifth set. Isner also went five sets in the second round at the French Open last month, losing 18-16 to Paul-Henri Mathieu. He has been eliminated in five sets in each of the past three Grand Slams.
