These two players have met each other seven times before. Interestingly, Anderson leads the way with four wins to three for Wawrinka. Even more interestingly, Anderson has won all four of most recent clashes - at the Indian Wells, Canada and Paris Masters last year and at Queen's this year. Wawrinka has been playing that down though: they have never faced each other in a best of five sets match before so this will be a different match all together. So Wawrinka reckons, anyway.
On account of the rain that has already affected today's schedule and is forecast to wreak havoc on the rest of tonight's and particularly tomorrow's order of play, French Open champion Stanislas Wawrinka's clash against Kevin Anderson has been moved out to Louis Armstrong.
