Medvedev closer to reclaiming top ranking as 'grateful' Osaka eases into Miami quarters

Daniil Medvedev moved to within two wins of reclaiming the ATP's No 1 ranking after easing past 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 will replace Novak Djokovic at the top of 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 No 1 ranking after a surprise third-round loss at Indian Wells, will be American Jenson Brooksby, who defeated Spain's Roberto Bautista Agut 6-3, 5-7, 6-4.

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

Alcaraz, 18, beat world No 5 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, 6-4 and will meet Serbian Miomir Kecmanovic, a 7-6, 6-3 winner over Sebastian Korda.

Fritz said it is all about managing expectations having battled through an ankle injury to win the Indian Wells title.

"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
