Exhausted Kevin Anderson called for Grand Slam chiefs to introduce a cut-off point for final set marathons after the South African reached the Wimbledonfinal by winning the second longest ever singles match at a major.

Anderson survived an incredible endurance test in the semi-finals on Friday, beating John Isner 7-6 (8/6), 6-7 (5/7), 6-7 (9/11), 6-4, 26-24 in six hours and 36 minutes.

The 32-year-old is the first South African man to reach the Wimbledon final for 97 years.
