Iga Swiatek and Carlos Alcaraz underlined their hard court credentials ahead of the US Open with victories over Jasmine Paolini and Jannik Sinner respectively in the women's and men's singles tournaments at the Cincinnati Open.

Iga Swiatek shrugged off lingering weariness to partner Casper Ruud to back-to-back victories in the revamped mixed doubles competition at the US Open on Tuesday. Swiatek — who on Monday had battled through a two-hour tussle with Jasmine Paolini to win the Cincinnati Open — looked full of energy as she and Ruud powered into Wednesday's semi-finals.
