Novak Djokovic and Carlos Alcaraz had wildly different days at the US Open.
Djokovic continues to cement his greatest of all-time status with yet another astonishing record, while Alcaraz crashed out of the tournament.
The Spaniard crashed out in the second round in one of the biggest shocks of all time when he lost to Botic van De Zandschulp.
The world number three came into the tournament in New York aiming to make it three grand slams in a row, having triumphed at the French Open and Wimbledon.
World number 74 Van De Zandschulp produced the result of his life to win 6-1 7-5 6-4 in front of a stunned US Open crowd.
Alcaraz said: “It was a fight against myself, in my mind during the match.
“In tennis, you are playing against someone that wants the same as you, to win the match, and you have to be as calm as you can just to think better in the match and try to do good things.
“Today I was playing against the opponent, and I was playing against myself. I mean, I had a lot of emotions that I couldn’t control.
“The tennis schedule is so tight. I’ve been playing a lot of matches lately, you know, with Roland Garros, with Wimbledon, Olympic Games.
“I took a little break after the Olympic Games. I thought it was enough. It was really helpful for me. Probably it wasn’t enough.”
Djokovic, however, sailed through to the second round at Flushing Meadow after Laslo Djere retired 6-4, 6-4, 2-0 due to injury.
This was his 90th win at the US Open – meaning he is the only player EVER to have 90 wins or more at each Grand Slam.
