There weren't many surprises on the women's side, but for the men, it was a very different story. Day 4 of the Miami Open was full of unseeded players rising up to the occasion.

The world No. 2 kept her winning streak alive against Ajla Tomljanovic by posting a 7-6 (3), 6-4 victory to reach the third round. Osaka, playing her first match since dismissing Jennifer Brady in the Australian Open final, has claimed 22 consecutive matches. She has never advanced beyond the third round in her four prior Miami appearances.
The Brit has been making noise throughout the first quarter of the year. Norrie notched a 7-5, 7-5 win over No. 9 seed Grigor Dimitrov to capture his fifth victory over a Top 40 player this season. He will carry a 3-2 lead in his head-to-head series against American Taylor Fritz when the two meet for a spot in the round of 16.
Norrie wasn't the only player to spring a sizable upset. The 104th-ranked Duckworth rolled past No. 8 seed David Goffin, 6-3, 6-1, to continue his campaign. By winning back-to-back main draw matches at an ATP Masters 1000 event for the first time, Duckworth is projected to return inside the Top 100 in the new rankings come April 5.
The Australian continues to make his 2021 count. After claiming his first ATP title last month in Singapore, Popyrin is now into the third round on his Miami debut. Following his win over Feliciano Lopez, the 21-year-old handed Reilly Opelka a 6-4, 6-2 loss to set up a clash with No. 1 seed Daniil Medvedev.
In her first meeting against countrywoman Sloane Stephens, the teenager easily moved past the 2017 US Open champion, 6-3, 6-3. The No. 28 seed will look to improve upon her best Miami showing when she next takes on another queen of Flushing Meadows, Bianca Andreescu.
