Medvedev reaches last 16 in Miami, Osaka into quarters

:Top seed Daniil Medvedev moved a step closer to reclaiming the world number one ranking as he beat Spaniard Pedro Martinez 6-3 6-4 on Monday to reach the last 16 at the Miami Open, while Naomi Osaka cruised into the quarter-finals of the women's draw.

Medvedev, who can replace Novak Djokovic in the rankings if he reaches the Miami semi-finals, fired down 14 aces and broke Martinez three times to secure victory in 84 minutes.

"I just felt like I had to be more consistent, and the more consistent one today would win," Medvedev said.

"I managed to just make a few less errors at important moments, serve even better, and it was a small margin but I managed to win and I'm really happy."

Up next for the Russian, who lost the number one ranking after a surprise third-round loss at Indian Wells, will be American Jenson Brooksby, a 6-3 5-7 6-4 winner over Spain's Roberto Bautista Agut.

Spanish 14th seed Carlos Alcaraz will meet Stefanos Tsitsipas after both enjoyed straight-set wins over Marin Cilic and Alex de Minaur respectively.

The 18-year-old Alcaraz beat Tsitsipas in their only previous meeting, a five-set thriller at last year's U.S. Open.

"He is a great player," the Greek third seed said of Alcaraz.

"For me it will be a great challenge, the ones that I like."

Indian Wells champion Taylor Fritz dispatched fellow American Tommy Paul 7-6(2) 6-4 and will meet Serbian Miomir Kecmanovic, a 7-6(4) 6-3 winner over Sebastian Korda.

Fritz said it is all about managing expectations.

"I didn't really think about winning Indian Wells until I had match point in the final," he said.

"So I'm approaching this one the same way. I don't expect to win the tournament, but I take it one match at a time, and you never know."
