Defending champion Jannik Sinner raced to victory at the Australian Open on Saturday to sweep into the last 16 as Iga Swiatek demolished Emma Raducanu. 

Italian World No. 1 Sinner dropped a set for the first time in 14 matches in the second round. But there were no such wobble against the unseeded Marcos Giron on Rod Laver Arena as he sprinted home 6-3, 6-4, 6-2 in 2hr 1min, slamming 35 winners and eight aces.
