Osaka began Monday's match against Riske in strong fashion. She saved four break points in the first game of the match before breaking in the next game to take a 2-0 lead. 

The Japanese tennis star took the first set 6-3 but stumbled early in the second set, going down 2-0 before roaring back to win four games in a row and reassert her dominance for the win. 

Osaka will take on Danielle Collins in the next round. It will mark just her second quarterfinal appearance over the last year, having not reached a quarterfinal since an Australian Open warm-up tournament in Melbourne in January. 

The 24-year-old has struggled with her mental health over the last year and has seen her world ranking slip to No. 77. However, a win at the Miami Open could help set her on the right path leading up to Roland Garros in May.

As for Medvedev, he also got out to a strong start against Martinez on Monday, breaking to take a 5-3 lead before closing out the first set in dominant fashion. He carried that momentum into the second set, causing Martinez a lot of struggles to grab a 6-4 win.

Medvedev will face Jenson Brooksby in the round of 16. If he can reach the semifinals of this tournament, he'll reclaim the world No. 1 ranking from Novak Djokovic, who is unable to compete in the United States because he is unvaccinated. 

The Russian tennis star was ranked No. 1 entering the BNP Paribas Open at Indian Wells but was upset by France's Gael Monfils in the round of 32 to lose the top ranking.
