Jannik Sinner continues the defence of his Australian Open title as he takes on Italian countryman Luciano Darderi in the fourth round.
Sinner admitted he got “lucky” in his third-round win over Eliot Spizzirri as the defending champion was saved by the heat rule. Sinner was cramping and looked to be in big trouble before the tournament’s heat stress level enforced the roof to close, as the 24-year-old second seed recovered to close out victory.
