Jannik Sinner brushed off concerns about his health with a brutal destruction of home hope Alex De Minaur in the quarter-finals of the Australian Open.
The two-time defending champion was in real trouble in his previous round against Holger Rune, taking a long medical timeout and visibly shaking, and admitted afterwards that he was not feeling well.
