John Millman shakes Roger Federer's hand after his stunning fourth-round victory at the US Open on Monday night.

Millman: "I'll Remember This For A Long, Long Time"

Australian looks ahead to Djokovic clash with new belief

Seventy minutes after the biggest win of his career over Roger Federer at the US Open, John Millman was still in a daze as he faced the tennis world’s media shortly after 2 a.m. local time.

“This is a little bit new to me, a quarter-final of a Grand Slam,” said Millman, after taking an ice bath following his first Top 10 win. “It's very new. I'm just trying to just keep to those routines that I've been doing. It's a late finish, but I'll try to get plenty of sleep.

“Hopefully I create a few more memories. I'll obviously remember this [win] for a long, long time. I hope the people who are watching here and back home remember it, too. I think that's all part of tennis, sharing the experiences with those close to you. It's extremely special.”

His 3-6, 7-5, 7-6(7), 7-6(3) victory over Federer broke a 10-match losing streak against players in the Top 10 of the ATP Rankings.

“I always was of the opinion that I was in the fourth round for a reason,” said Millman. “I've never played anyone's reputation. That's been a constant with me... because I think if you do that, then you start behind the eight-ball straightaway.

“At the start, I was deer in the headlights a little bit. It's a different environment. But as the match went on, I felt very comfortable in terms of my mental state. [I] felt very relaxed. That obviously helped me tonight.”

“I started to find my feet a little bit, I think, in that second set, when he served for it. I managed to break back [and I] started to get a lot more comfortable in the surroundings.”

Millman, who overcame two shoulder surgeries in 2013 and groin surgery in 2016, will now break into the Top 40 of the ATP Rankings for the first time on 10 September, following the conclusion of the US Open.

“It’s tough to start all over again a few times,” said Millman, who was as low as No. 235 just 12 months ago. "But you do it. And you do all those moments in rehab, you do all that for something like this. It all becomes a little bit more rewarding.”

He will now prepare to meet two-time former US Open champion Novak Djokovic on Wednesday. When asked whether he could cause another upset, the 29-year-old said, “Yeah, why not? I think it's a disservice to who I am if I go out there and don't have that belief."

The World No. 55 is now 18-15 on the season, which includes a runner-up finish in his first ATP World Tour final at the Gazprom Hungarian Open (l. to Cecchinato) on 1 April.
