08:37 CET - In an incredibly late finish, Alexander Zverev (27) has finally managed to defeat a resilient Tomas Martin Etcheverry (25) 5-7, 7-5, 6-1, 6-3. With some of the big names being knocked out, surely this is a huge chance for Zverev to win his maiden major.
07:53 CET - And just now, as the clock nears 2am in New York, Aryna Sabalenka (26) has made her way into the fourth round, beating Ekaterina Alexandrova (29) 2-6, 6-1, 6-2. Incredibly, Alexander Zverev (27) is still on court at these early (or late) hours, leading Tomas Martin Etcheverry (25) 5-7, 7-5, 6-1.

07:40 CET - One day after Carlos Alcaraz was on the receiving end of a historic upset, I didn't expect to be writing this too. 24-time Grand Slam winner and Olympic Gold medalist Novak Djokovic (37) has also been DUMPED OUT, losing to the recent Montreal champion Alexei Popyrin (25) 4-6, 4-6, 6-2, 4-6.
A remarkable result which means that for the first time since 2002, a member of the big three (Djokovic, Nadal and Federer) hasn't won a slam.
Popyrin was excellent, but it was a pretty dismal display from Djokovic, who hasn't been able to find his best form this tournament. With Alcaraz and him now gone, it sure opens up the tournament for the rest of the field.
Home favourite Madison Keys (29) was also defeated in a thrilling battle, with Elise Mertens (28) battling to a 6-7(5), 7-5, 6-4 victory.
In other results, Frances Tiafoe (26) reversed last year's result to beat fellow American Ben Shelton (21) 4-6, 7-5, 6-7(5), 6-4, 6-3, Brandon Nakashima (23) delighted the home crowd to upset Lorenzo Musetti (22) 6-3, 3-6, 6-3, 7-6(4), while Taylor Fritz (26) and Casper Ruud (25) also won - with the latter having to fight back from two sets down against Juncheng Shang (19).

Gauff was off the pace in the first set but stepped her level up in the second and third set as Svitolina's level dropped.
19:52 CET - Paula Badosa (26) has come through an almighty battle with Elena Gabriela Ruse (26), saving a match point on her way to a 3-6, 6-1, 7-6(8) win. A big victory for the in-form Spaniard.

15:15 CET - Who would have expected Carlos Alcaraz (21) to go down to Botic van de Zandschlup (28) in straight sets? Not many people if anyone! That was the major shock in last night's action as the second round wrapped up at Flushing Meadows.
