Sixth time unlucky, a devastated Alex de Minaur is lamenting another "wasted opportunity" after blowing surely his best chance yet to reach a grand slam semi-final.
With his serving once again letting him down badly, Australia's No.1 was still left reflecting on golden opportunities missed as he went down 4-6 7-6 (9-7) 7-5 7-6 (7-4) to Felix Auger-Aliassime in a curiously uneven and largely flat US Open quarter-final marathon.
After five previous last-eight disappointments while searching for that elusive breakthrough, de Minaur was a set up, then a break up before missing out on a set point in the second, and still looking the better player in the latter stages of the third as he rallied impressively.
