Australian wildcard Jordan Thompson is the first player through to the Sydney International quarter-finals after fighting back to claim a three-set win over Troy Daniel.

Thompson found himself a set and break down on Tuesday evening, but took advantage of the tiring world No.78 to win 3-6 7-6 (7-5) 6-0 in two hours and 26 minutes.

Daniel had Thompson on the ropes early in the second set but after losing a tense tiebreaker, completely fell apart in the third.

Thompson’s victory comes just a day after the world No.72 beat Adrian Mannarino in the first round in what was his first win over a top-50 opponent in more than a year.

The 24-year-old now progresses to a final-eight match-up against countryman and Australian No.1 Alex de Minaur or American qualifier Reilly Opelka.

It is the first time the Sydneysider has reached the quarter-finals in his home city in five attempts, having made the second round on two occasions.
