A couple of minutes later, the fear became reality, as Madison Keys served up the first 6-0 set, or bagel, that Świątek has received in almost four years. Not since a match against Daria Kasatkina at Eastbourne in England in June 2021 had she lost a set 6-0.

In a blow to his clay court season, Alex de Minaur's Madrid Open comes to a crushing end, beaten in straight sets by Italian Lorenzo Musetti.

The second seed will next square off with Coco Gauff, who beat 18-year-old Mirra Andreeva for the third time in as many meetings, 7-5, 6-1.
