Sinner, 23, isn’t likely to be troubled first up. He’s in line to face Czech player Vít Kopriva, providing the world No.80 can beat a qualifier in his first-round match.
It is not until the last-16 that things potentially get tricky for the Italian, where he is in line to play 13th seed Tommy Paul. Fourth seed Taylor Fritz is also on his side of the draw, although the pair cannot meet until the semi-finals.

Alcaraz will return against the winner of Italian Mattia Bellucci or Ukraine’s Damir Dzumhur. The latter was ranked 18th some seven years ago, but both men now lie outside the world’s top 50.
If he wants to gain a measure of revenge on Sinner, the 22-year-old will need to overcome Alexander Zverev if the two rivals make the semi-final stage. The Spaniard won the title in Cincinnati 2023, before Sinner prevailed 12 months ago.
