Alexei Popyrin will be looking to back up the biggest win of his career and continue on in the Adelaide International on Wednesday.
Popyrin, who competed in the main draw via qualifying, stunned world No.6 Felix Auger-Aliassime in the opening round.
It marks the biggest win of the 23-year-old’s career to date and has set up a clash with unseeded American Marcus Giron on Wednesday night.

A deep run at the event, which offers 250 ranking points to the winner, would see Popyrin’s ranking surge from its current position of 120.
Popyrin is aiming to reach his third tour-level quarterfinal and his first since February 2021, when he won his first and only ATP title in Singapore.
In the United Cup, only six teams remain, with the City Finals beginning on Wednesday.
