Alex Molcan

Alex de Minaur retired injured during the Beijing Open final, handing Novak Djokovic his seventh title at the tournament. The Australian has since travelled to the Shanghai Masters carrying an injury concern, advancing to the round of 32 after Alex Molcan's withdrawal, and earlier saved a match point to beat Quentin Halys. De Minaur has also floated a rule change allowing only one ball toss on serve.
