That's it, Roger Federer has "found (his) rhythm" and qualified for Sunday's 13th quarterfinal of the US Open without worry, unlike Serena Williams who has experienced an injury alert before joining the quarters for the 16th time.
The titleholder Novak Djokovic was to succeed them at the end of the night session on the court Arthur-Ashe. But the surprises of the day came from short Louis-Armstong with the consecutive eliminations of N.2 and World 3 Ashleigh Barty and Karolina Pliskova.
"When I feel calm in my legs when I hit a ball, in the backhand, forehand or volley, that means I entered my tournament and that's the feeling I had today" against David Goffin (15th), detailed Federer.
The world No.3 had lost a set early in the game in his first two rounds, before mastering head and shoulders in the third round the British Daniel Evans 6-2, 6-2, 6-1 in 1:20.
He was even more severe with Goffin than he swept 6-2, 6-2, 6-0 in 1:19.
"He gets more and more level of play, he relaxes, he tries more and more, he succeeds and it becomes complicated. And here, it's hard to stay in the game. When we see it unfolds, we're just the punching ball, then we go back (to the locker room), "said the Belgian.
Federer scored 10 aces, scored 83% on his first serve, converted 9 of his 10 break points, scored 35 winners and committed just 17 unforced errors …
– Federer "very happy" –
"I'm very happy with my level today," said Switzerland's record-holder at Flushing Meadows with Pete Sampras and Jimmy Connors.
He qualified for his 13th quarterfinal at the US Open, like Andre Agassi but four more lengths of the record of Connors. In total, he will play, at age 38 against Grigor Dimitrov (78th), his 56th quarterfinal Grand Slam, a record.
Not surprisingly, Serena Williams also qualified by defeating Croatian Petra Martic (22) 6-3, 6-4. Unsurprisingly, but not without fear since the American twisted her right ankle she quickly made it hard.
"I said to myself, oh no, not again, I just start walking again!", She said, referring to knee and back injuries that thwarted her 2019 season.
She reached the quarter-finals of the US Open for the 16th time and won the 1st of her six titles 20 years ago.
"I'm so old?" She exclaimed when asked what it was doing to her.
– Surprise Barty –
Ashleigh Barty, winner of Roland-Garros, fell to the Chinese Wang Qiang (18th) 6-2, 6-4 in 1h22.
"I just tried to do my best," said Wang, who had never reached the quarter-finals of a Grand Slam.
How will she prepare for her next match against Williams? "It's my coach's job to tell me how to play, I'm going to savor this win," said the 27-year-old.
For his part, Barty could only see the superiority of his opponent of the day: "Q (sic) was very strong, very solid. She was able to play very deep to put me in trouble. I had some opportunities, but it's frustrating because on the important points today Q (sic) has played much better, "said the 23-year-old Australian.
And Pliskova, still looking for a Grand Slam title, was eliminated by Johanna Konta (16th) 6-7 (1/7), 6-3, 7-5.
The 28-year-old Briton had never passed the Flushing Meadows Round of 16 so "climbing one more step is a huge achievement for me!" She said to the audience.
Konta has already reached the semifinals in Grand Slam, Australia in 2016, Wimbledon in 2017 and Roland Garros on three occasions this year.
