Medvedev one win away from top ranking, dominant Osaka eases into Miami Open semi-finals

Daniil Medvedev is one win away from retaking the world No 1 spot after moving past American Jenson Brooksby 7-5, 6-1 and into the Miami Open quarter-finals on Tuesday.

The US Open champion lost his serve in the first game but found momentum after fending off two more break points in the fifth, winning the final four games of the first set in which he fired down six aces. He ripped through the second set in less than half an hour, dropping one first serve point.

Medvedev will face defending champion Hubert Hurkacz in the quarters, with a win moving the Russian back to the top ranking on Monday, two weeks after he lost the spot to Novak Djokovic.

"At this moment, I don't feel any pressure," Medvedev said. "To be in the semi-finals, I knew before the tournament that I have to be there if I want to be No 1.

"It's great that I have this chance. Only one match left. Of course maybe during the match, pressure can start to build up, depending on how the match is going ... But at this moment it's just a lot of extra motivation to try to make this one more step."

Australian wildcard Nick Kyrgios lost to Italian Jannik Sinner 7-6, 6-3 after a dispute with the chair umpire.

Kyrgios received a point penalty for bad behaviour in the first-set tiebreak and in between sets angrily and repeatedly asked the chair umpire "What is unsportsmanlike?" before walking to his bench and whacking his racket against the court. The gesture earned him a game penalty, allowing Sinner to open the second set up a break.

Elsewhere in the day's action, fourth-ranked German Alexander Zverev overcame a solid defensive effort from Australian qualifier Thanasi Kokkinakis to win 6-4, 6-4 and set up a quarter-final clash with eighth-ranked Casper Ruud.
