Alex de Minaur has added the Atlanta Open to his Sydney International title win from earlier this year after a dominant victory over American Taylor Fritz.

De Minaur, 20, broke Fritz’s serve twice in the first set and prevailed in a second-set tiebreaker to seal his second ATP Tour trophy with a routine 6-3 7-6 (7-2) win in Sunday’s final.

The players traded comfortable service holds throughout the second set to force the tie-break, which De Minaur dominated.

We have a winner!

The youngest finalist in the decade-long history of the Atlanta Open, De Minaur will move up to world No.25 when the rankings are updated on Monday.

“This one is really special to me. I felt like I really needed this,” the Australian told atptour.com.

“To start the year with a bang and then be slowed down by injuries … you expect your level to be right there once you come back, but you have to slowly grind your way back.

“I’ve been playing great tennis and felt like if I could keep it all together, the good results will come. This is a week that will really help me out.”

De Minaur will go into next month’s US Open full of confidence.

“I don’t think I could start the American hardcourt season any better than this,” he said.

“I’m happy with where I am and enjoying every day. I can’t wait to get back on court and keep improving.”

De Minaur became just the third player in the recorded history of the ATP Tour to win a tournament without ever facing a break point on his serve. He conceded just only first serve points for the entire tournament.
