Swiatek dominates Osaka to win Miami Open and complete historic 'sunshine double'

Iga Swiatek celebrated becoming the new women's world No 1 in ultimate style by thrashing Naomi Osaka to win the Miami Open title on Saturday and completing a historic 'sunshine double'.

The Polish 20-year-old became only the fourth, and youngest, player to win the Indian Wells and Miami titles in the same year following Steffi Graf, Kim Cljisters, and Victoria Azarenka with a 6-4, 6-0 win over Osaka.

Swiatek, who will be formally confirmed as world No 1 when the new WTA rankings are announced on Monday following Ashleigh Barty's sudden retirement, has now won 17 straight matches, a winning streak that includes titles in Doha, Indian Wells and now Miami.

Osaka, 24, enjoyed a welcome return to form in Florida, even if the four-time Grand Slam champion's first final since the Australian Open in 2021 ended in a comprehensive defeat.

"I feel privileged to be among those players who have done this double before, I knew it would be tough playing these tournaments in a row but I took it step by step," said Swiatek, who won her maiden Grand Slam at the French Open in 2020 as a 19-year-old and will be the favourite to win another Roland Garros crown next month on her preferred surface.

"I was in the zone in the second set - that's the easiest way for me to be dominant. I was surprised I could handle all these matches. I am still the same person, though. My idols were like that and I don't want the success to change me in a negative way. It gives me confidence.

Swiatek headed into a seventh career final on the back of 16 straight wins – the last player to win 16 or more in a row was Osaka, between Cincinnati in 2020 and last year's Miami Open.

Osaka has been serving well this tournament but was broken by Swiatek to make it 3-2 in
