Following her 7-5, 6-4 final win over Jasmine Paolini to earn her first Cincinnati Open title on Monday night, the world No. 2 took a private jet along with Carlos Alcaraz to New York to arrive in time for the U.S. Open mixed doubles tournament Tuesday.

The American and the Briton denied three set points on serve in the sixth game and locked the result at 3-3. Pegula struggled on serve again in the eighth game and got broken at 15 after Casper's smash winner, with the European squad forcing a match tie break.

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.

Swiatek then explained: "That's not possible because when your agent asked my agent, I think, or you asked me, I had no idea what I'm signing up for. I was like, 'Yeah okay, I want to play with Casper.' But I didn't know what the tournament is going to look like so it must've been you."

Well, well, well. Look who’s back from the tennis wilderness. Iga Swiatek just reminded everyone why writing her off was about as smart as betting against a Polish powerhouse with a grudge.

Look no further than Iga Swiatek. Earlier this summer, the sky was falling for Swiatek. She failed to defend any of her clay court titles, sank in the WTA Rankings, and was fielding outlandish questions about possibly skipping the grass court season altogether (luckily, that did not happen).

Iga Swiatek on Tuesday shrugged off lingering weariness to partner Casper Ruud to back-to-back victories in the revamped mixed doubles competition at the US Open. 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 semi-finals.

The revamped US Open mixed doubles started yesterday at Flushing Meadows, with 16 pairs vieing for a chance to claim the title and $1 million winning cheque.
