John Millman has dumped Roger Federer out of the US Open in the fourth round in a stunning upset at the Arthur Ashe Stadium in New York .
The 29 year-old Australian, ranked 55th came from a set down to beat world number two Federer 3-6 7-5 7-6 7-6, to register his first top ten victory, to qualify for the quarter-finals.
Millman will now meet Novak Djokovic in the quarter-finals.
The Australian was dominated by Federer in the first set but turned the tables on the Swiss to take the second then held his nerve through two tiebreaks to secure the win in three hours and 34 minutes.
Second seed Federer, who had not dropped a set in his first three matches in New York, had 77 unforced errors and 10 double faults and landed just 49 percent of his first serves.
Millman said the victory had yet to sink in.
Im probably in a little bit of disbelief. I have so much respect for Roger and everything hes done for the game, he added. Hes a hero of mine. Today he was not at his best but Ill take it.
Maria Sharapova also lost to Carla Suarez Navarro in two straight sets 6-4 6-3.
It was a sweet victory for the 30 year-old Spaniard, who also marked her birthday.
Sharapova, the 2006 champion, had never lost a night session match in New York prior to her first Grand Slam meeting with Suarez Navarro.
Five-times Grand Slam champion Sharapova paid the price for 38 unforced errors and won less than half of her first serve points while committing eight double faults.
I didnt take care of the chances that I had, the Russian told reporters. By chances, I mean the balls that were a little bit shorter.
I hesitated to move forward. The balls where I did attack, I made unforced errors, especially on that inside-out forehand today.
With her most potent weapon not firing, Sharapova succumbed in one hour and 31 minutes under the floodlights at the Arthur Ashe Stadium, allowing 30th seed Suarez Navarro to record just her second career victory over the Russian in six attempts.
I just tried to be focused. I tried to think about not too much things, just my work, my job. Today it worked.
The Spaniard will meet last years runner up Madison Keys in the quarters and knows she will be the underdog against the 14th seeded American.
It will be a really tough match. She is from the United States so the crowd will probably help her, Suarez Navarro added.
