Jannik Sinner avoided plunging through the US Open trapdoor which claimed Novak Djokovic and Carlos Alcaraz when he stormed into the last 16 on Saturday. 

Australian Open champion Sinner raced past 87th-ranked Christopher O’Connell 6-1, 6-4, 6-2. The 23-year-old Italian’s win came a day after four-time champion Djokovic was sent spinning to his earliest loss in New York in 18 years by Alexei Popyrin.
