Osaka finds Miami groove

Former world No. 1 Naomi Osaka made it through to the quarterfinals at the Miami Open — just the second time she has managed to advance that deep in any tournament over the last year. Osaka beat Alison Riske of the U.S. 6-3, 6-4 on Monday, moving into a round-of-eight matchup with Danielle Collins. Osaka’s only other quarterfinal appearance in the last year was at an Australian Open warmup tournament in Melbourne in January. Before that, her most recent quarterfinals trip was at Miami a year ago. Osaka’s ranking has dipped to No. 77 — it could get somewhere around No. 30 if she wins the Miami title — and she hasn’t won a tournament since that Australian Open last year. Collins, the No. 9 seed from the U.S., needed just over an hour Monday to win her fourth-round match against No. 8 Ons Jabeur, 6-2, 6-4. Daria Saville also got into the quarterfinals, surviving a three-hour match to beat Lucia Bronzetti 5-7, 6-4, 7-5. No. 2 Iga Swiatek, who is already assured of moving to No. 1 next week, also rolled into the quarterfinals with a 6-3, 6-1 win over No. 14 Coco Gauff. In the men’s third round, Daniil Medvedev is now two wins away from reclaiming the No. 1 ranking. The top seed in Miami beat Spain’s Pedro Martinez 6-3, 6-4. Next up for Medvedev is American Jenson Brooksby, who rallied from 0-4 down in the third set to upset No. 15 Roberto Bautista Agut 6-3, 5-7, 6-4. No. 11 Taylor Fritz defeated Tommy Paul 7-6 (2), 6-4 in an all-American third-round matchup. Defending champion Hubert Hurkacz also advanced, the No. 8 seed fighting past No. 29 Aslan Karatsev 7-5, 4-6, 6-3. No. 14 Carlos Alcaraz got by No. 21 Marin Cilic 6-4, 6-4.
