Holger Rune didn't have anything against Jannik Sinner taking a medical timeout but noted that a lengthy break ruined his rhythm. After the world No. 1 started to physically struggle late in the second set of their Australian Open round-of-16 match - the Italian's hands were shaking and his movement was impacted - the Dane won that set and also had the upper hand early in the third set.

The World No. 1, despite feeling unwell in sweltering conditions, kept up his title defense with a four-set triumph.
