Australian Open: Djokovic, Sinner, Osaka lead day 2 line-up, Tsitsipas dumped out
World No 3 Coco Gauff began her Australian Open campaign in style on Monday but former finalist Stefanos Tsitsipas became the biggest casualty of the tournament so far. Novak Djokovic begins his bid for grand slam history later on a blockbuster day two and Jannik Sinner starts the defence of the trophy he won 12 months ago.
