When the going gets tough Jordan Thompson's mind sometimes goes back, to January 2017, and a day of sweltering heat at Melbourne Park.
That was the first time, at the fourth attempt, he came back from two sets down to win, defeating Portugal's Joao Sousa, then ranked 39 places higher, 6-7 (2-7) 4-6 6-3 6-2 6-1 in three hours 22 minutes.
Thompson followed that by winning his next five-setter, against then top-20 player Jack Sock in the latter's home grand slam in New York, later that year.
