Stefanos Tsitsipas said he found “nirvana” on the tennis court as he recovered from two sets down to halt Rafael Nadal’s bid for a record 21st Grand Slam title at the Australian Open on Wednesday. 

Second seed Nadal was on course for a comfortable victory before Greece’s Tsitsipas turned the quarter-final around to prevail 3-6, 2-6, 7-6 (7/4), 6-4, 7-5 in four hours and five minutes.
