doping

Going into the US Open, Sinner had been marginally the more successful player over the past two seasons - even though he missed three months of this year because of a controversial doping case.

Sinner stayed bullish publicly as the debate raged about the doping case, while he was able to move on quickly from the brutal French Open defeat by Alcaraz.

British tennis player Tara Moore has been banned for four years for a doping offence, despite being cleared by an independent tribunal 18 months ago.

Perhaps this should come as no surprise, given that doping controversies are far from unusual in tennis.

Majchrzak reached a major fourth round having previously served a 13-month doping ban, while Jarry - who has an ear condition which affects his balance and vision - came through qualifying to reach the last 16.
