TOP MEN'S MATCH: SINNER v McDONALD

Controversy has surrounded Australian Open champion Sinner in the week before the year's final Grand Slam. The Italian escaped a doping ban having been cleared after twice testing positive for the banned drug clostebol in March.

Sinner, who maintains his innocence, has continued to play after successfully challenging provisional suspensions and comes into the match on the back of winning the Cincinnati title but he has been under intense scrutiny in New York so far.

"It's not ideal before a Grand Slam," Sinner said.

"But in my mind I know I haven't done anything wrong. I had to play already for months with this in my head, but remembering that I haven't done really anything wrong.

"I always respect that these rules and I always will respect these rules of anti-doping. Obviously a relief for myself having this result. It's just good to be back here ... I'll just try to enjoy as much as I can and hopefully have a good tournament."

The 23-year-old has weathered the storm so far but will hope to avoid a hostile reception from fans when he takes on American McDonald in the day session at Arthur Ashe.
