MIAMI: Daniil Medvedev moved into the last 16 of the Miami Open on Monday with a comprehensive straight-sets triumph over Spain's Pedro Martinez. The Russian top seed remains the favourite for the title and his 6-3, 6-4 victory was as clinical as the one which sent Andy Murray out of the tournament in the previous round.

Martinez competed well but once he was broken by Medvedev midway through the second set, the reigning US Open champion never looked back and wrapped up the win in one hour and 24 minutes. "I hit 14 aces and felt pretty good, the second set was tight but I managed to stay consistent," said Medvedev during a courtside interview. The 26-year-old will regain the world number one ranking by making the semi-finals in Miami. Medvedev will face 21-year-old Jenson Brooksby after the American defeated Roberto Bautista Agut 6-3, 5-7, 6-4 on Monday.

Brooksby made headlines at the start of the tournament for throwing his racket towards a ball-boy during a first round win which resulted in a $15,000 fine. Brooksby knows he has to channel his emotions in the correct way and hopes his decent form continues against Medvedev. A run to the fourth round of the US Open last year has been backed up with a last 16 defeat in Indian Wells and now the chance to reach the quarter-finals in Miami.

"This is a big learning curve for me," he told AFP. "I am definitely the type of player that needs to play with emotion. "But as my coach has said I have to work on balancing it better and finding other ways to let out frustration because what happened was unacceptable and I am definitely sorry. I need to learn from what happened. "Daniil's got a very solid game and is obviously in the top two in the world for a reason but the more matches I play on these big stages can only help me."

In another development, Naomi Osaka will face American Danielle Collins for a place in the semi-finals of the Miami Open after the Japanese star beat Alison Riske 6-3, 6,4 on Monday. Osaka has responded strongly in Florida, advancing to the quarter-finals after leaving Indian Wells in tears earlier this month after being heckled by a fan.

The four-time Grand Slam champion, who received a walkover in the previous round, is yet to drop a set and remains one of the favorites to land the title. "I am definitely happy," Osaka said afterwards. "Last year I got to the quarters in Miami after winning in Australia and I am winning matches here this year too but I feel more grateful-this is one of the funnest times of my life." "There were a lot of things running through my mind last year," added Osaka who was able to stay firmly on the front foot against American Riske while saving seven of eight break points faced.

"Maybe it was trying to return to number one or other things which aren't that important but at the time was so heavy in my head. I am just happy to be healthy," added Osaka, who recently revealed she has benefited from therapy to address her mental health issues. Ninth seed Collins, who reached the semi-finals in Miami in 2018, beat Ons Jabeur 6-2, 6-4 earlier in the day.

Newly minted world number one Iga Swiatek also advanced comfortably on Monday, sweeping aside the 14th-seeded Coco Gauff 6-3, 6-1 in 1hr 16min. The second-seeded Swiatek, who took over the top ranking on Friday in the wake of the shock retirement of Ashleigh Barty, is now on a 14-match unbeaten streak. The 20-year-old Pole won the WTA 1000 event in Doha and then took victory at Indian Wells earlier this month.

She is bidding to become only the fourth woman to win Indian Wells and Miami in the same season after Steffi Graf, Kim Clijsters and Victoria Azarenka. Swiatek believes she is a more complete competitor now than when she triumphed in the pandemic-delayed French Open in 2020 for her maiden Grand Slam win. "Right now I feel more prepared and I feel like I'm in a better place," Swiatek said. "So there is more excitement and more like satisfaction and actually like positive thoughts and emotions.

"Because after Roland Garros, it was really a mess... I have been doing well like cutting off the expectations from the outside. It was always, for me, harder to deal with my own expectations that I had for myself." While Swiatek is looking to extend her winning streak, Czech teenager Linda Fruhvirtova's impressive run came to an end in the last 16. The 16-year-old-the youngest player to reach the fourth round since 2004 - was eliminated by fifth seeded Spaniard Paula Badosa. Badosa powered to a 6-2, 6-3 victory in 1hr 22mins to advance to the last eight. - AFP
