Exhausted Kevin Anderson called for Grand Slam chiefs to introduce a cut-off point for final set marathons.
“I hope this is a sign for Grand Slams to change. For us to be out there for that length of time. I really hope we can look at this, because at the end you don't feel great,” Anderson said.
“Just playing like that in those conditions was tough on both of us.”
“If I was on the opposite (losing) side I don’t know how you take it,” he added.
