Djokovic sets up Fritz showdown | Email Taha here

Felix Auger-Aliassime is here after trumping the third seed Alexander Zverev – this is his first time in the fourth round of the US Open since his run to the semis in 2021. He thunders an ace down to hold his serve and go 1-0 up in the first set against Andrey Rublev.

Alex de Minaur takes the first set against Leandro Riedi 6-4, secured after Riedi goes long with a blasted forehand. The Australian has a peculiar record at the slams, reaching the quarter-finals of all four tournaments. But he’s still waiting for his first semi-final appearance.
