Former champion Stan Wawrinka downed Greek star Stefanos Tsitsipas in the longest match of this year's French Open on Sunday to set up a quarter-final clash with Roger Federer. Wawrinka sealed a stunning 7-6 (8/6), 5-7, 6-4, 3-6, 8-6 fourth-round victory with a magnificent winner from yards behind the baseline after five hours and nine minutes on Court Suzanne Lenglen.
He has a 23-3 losing head-to-head record against close friend and fellow Swiss Federer. "It's incredible, lots of emotions. Thanks to all the fans for staying and (the) support," said the 34-year-old Wawrinka after the third longest match in the last 20 years at the French Open.
