Naomi Osaka makes 4th round in Miami for 1st time with walkover

MIAMI -- Naomi Osaka advanced to the fourth round of the Miami Open for the first time in her career Sunday when qualifier Nina Stojanovic withdrew from their match shortly before the scheduled start because of a right thigh injury.

Osaka, ranked No. 2, has won 22 consecutive matches since her most recent defeat in February 2020, and she earned her fourth Grand Slam title at the Australian Open last month. But in Miami, where she is making her fifth appearance, she has previously made early exits.

She'll next face No. 16 Elise Mertens, who won a seesaw match against No. 22 Anett Kontaveit 6-2, 0-6, 6-2.

Also Sunday, No. 4 Sofia Kenin lost to No. 27 Ons Jabeur 6-4, 4-6, 6-4.

No. 29 Jessica Pegula defeated No. 6 Karolina Pliskova for the third time this year 6-1, 4-6, 6-4.
