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.

Iga Swiatek kept her Madrid Open title defence alive, as she avenged her Australian Open defeat to Madison Keys with a 0-6, 6-3, 6-2 win against the American in the quarter-finals on Wednesday. Swiatek is famous for dishing out 6-0 sets and it was unusual for the five-time Grand Slam champion to be on the receiving end of one.
