Indian Wells champion Carlos Alcaraz kept his hopes for a Sunshine Double alive with a 6-3, 6-3 win over Lorenzo Musetti to reach the Miami Open quarter finals for the third straight year on Tuesday.

The Spaniard needed less than 90 minutes to dispatch the 23rd seed from Italy, pounding forehands and winning 18 of 22 points when he charged to the net.

Alcaraz broke serve to start the match and again to grab the drama-free first set against his overmatched opponent.

Musetti’s best moment came in the second set when he hit a front-facing tweener lob over Alcaraz’s head and ended the point with a volley to gasps from the fans at Hard Rock Stadium. But that was not enough to rattle Alcaraz who cruised to victory.

“Without a doubt, this is the best I’ve been feeling,” Alcaraz, who had struggled with an ankle injury earlier in the season, said after winning his ninth consecutive match.

“I’m feeling great on the court, I’m moving great with no injuries because I don’t think about the ankle anymore on the court.”

Alcaraz will next face 11th seed Grigor Dimitrov after the Bulgarian’s career renaissance continued with a gritty 3-6, 6-3, 7-6 (3) win over Poland’s Hubert Hurkacz.

Daniil Medvedev took another step towards retaining a title for the first time in his career as the Russian third seed beat Germany’s Dominik Koepfer 7-6 (7-5), 6-0 to make the quarter finals.

“Sometimes it happens when you lose the first set the way he lost ... it brings your (opponent’s) energy down and I knew that I had to use it (to my advantage) in the beginning of the second set that’s where it was the most important,” Medvedev said after collecting his 350th career win.

The Russian will face Chile’s Nicolas Jarry, the 22nd seed, in the last eight, after he beat seventh seed Casper Ruud of Norway 7-6 (7-3), 6-3.

In other early action, unseeded Czech Tomas Machac beat Italy’s Matteo Arnaldi 6-3, 6-3 to reach his first Masters 1000 quarter final.

Machac faces a tough task against second seed Jannik Sinner, who overcame a first-set deficit before ultimately coasting to a 6-4, 6-3 victory to reach the quarters.

Fabian Marozsan, who took out sixth seed Holger Rune earlier in the tournament, continued his stunning run by defeating ninth seed Alex de Minaur 6-4, 0-6, 6-1.

The unseeded Hungarian, who stretched his win-loss record against top-10 opponents to 4-1, could face a daunting task in the last eight against an in-form Alexander Zverev.

The fourth-seeded German set up the clash after outclassing Russian Karen Khachanov 6-1, 6-4 in a late night contest.
