Taylor Fritz downs Aleksandar Vukic to win Atlanta ATP crown
US number one Fritz dug deep to overpower Australia's Vukic, ranked 82nd in the world, in 2hr 16min, winning 7-5, 6-7 (5/7), 6-4.
Fritz looked to be heading for a straight sets victory after taking two match points on Vukic's serve while leading 6-5 in the second set.
But Vukic showed great character to claw his way back from the brink, eventually holding serve with an ace to force a tie-break.
The 27-year-old from Sydney then relied on his thunderous serve to grab the tie-break as Fritz was left ruing a golden chance to wrap up victory.
However the American regained his composure in the deciding set, claiming the decisive break in the seventh game to take a 4-3 lead before holding for 5-3.
Vukic then held comfortably but there was no way back as Fritz produced a dominant service game to seal victory.
A booming ace - his 16th of the tournament - brought up three match points at 40-0, and another powerful serve left Vukic flailing with a wild return to give the American the win.
