In the all-Swiss semi final at the Australian Open in Melbourne, Roger Federer playing Stan Wawrinka was poised to cross the 100 million US Dollar earning from winnings alone. He wouldn’t have been aware of it since he would have lost count of the money that has kept pouring into his account from the matches he won and the endorsements he netted. But coming after a six-month injury break into top-notch tennis, Federer surely remembered how to play the sparkling cross court back hand and how to deliver shorts with precision. For after all, his memory will be full of the precise details-- the power, the trajectory, the angles-- that even at this age would rattle many of tennis biggies including Tomas Berdych who was dispatched in straight sets.
