Tennis news 2021: Naomi Osaka Maria Sakkari result creates WTA world number one ranking history for Ash Barty

Ash Barty is guaranteed to hold on to the world number one ranking after Naomi Osaka was stunningly beaten at the Miami Open.

Osaka, the reigning US and Australian Open champion, was upset by Greece’s Maria Sakkari 6-0 6-4 in the quarter-finals, ending the Japanese star’s 23-match win streak.

The world number two needed to win the tournament after Barty progressed to the semi-finals with an impressive three-set win against Aryna Sabalenka a day earlier.

It means Barty will retain No. 1 in the rankings for at least another five weeks, taking her reign at the top of the women’s game to 74 weeks.

While much of that time was spent sitting at home while COVID-19 suspended the tour, Barty has now moved to ninth all-time for most weeks at number one.
