Iga Swiatek calls out US Open doubles partner and corrects him during post-match interview

Iga Swiatek hilariously cut off Casper Ruud and corrected him during their post-match interview following their US Open mixed doubles win.

Swiatek and Ruud have teamed up for this year's US Open mixed doubles.

It's a revamped tournament as just four games will be required to win a set in matches before the final, with no-advantage scoring and 10-point match tie-breaks instead of a third set throughout.

Swiatek's involvement at the US Open was in doubt as she won the Cincinnati Open before she was due to take to the court in Flushing Meadows.

But she jetted straight to New York and landed around 12 hours before stepping onto Arthur Ashe Stadium for her opening match in the mixed doubles.

And the pair of tennis stars have recorded two big wins and are one game away from the final.

Swiatek and Ruud have developed a strong synergy, having gained an understanding of each other’s styles.

They beat Madison Keys and Frances Tiafoe 4-1, 4-2 in their opening match on Tuesday before seeing off Caty McNally and Lorenzo Musetti by the same score.

Speaking after their latest victory, the pair of stars jokingly butted heads over the origins of their link-up.

Asked who reached out first, the Norwegian said: "I had in mind that maybe if Iga wanted to play, I’d be down, and then she actually shot me a text and asked if I wanted to play."

Swiatek, who won this year's Wimbledon title, interrupted Ruud and shut him down.

"What? You texted [me]," she replied, cutting him off.

Ruud hit back: "That’s not possible because when your agent asked my agent, 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 even look like, so it must have been you."

After they stepped off the court, Ruud continued to poke fun at the Polish star.

He commented on her Instagram post: "So glad you texted me," he wrote, accompanied with a winking emoji.

Swiatek and Ruud face Jack Draper and Jessica Pegula in the semi-finals for a spot in the US Open mixed doubles final.
