Il Nuovo Postiglione - Alcaraz blasts Paul to set up Fritz clash

Alcaraz, the defending Miami champion and also the winner at Indian Wells earlier this month, will face another American in the last eight when he comes up against Taylor Fritz.

Paul came into the match having won his last 12 encounters with Spanish players, including wins over Alcaraz and Rafael Nadal last year, but he was unable to get a foothold in the contest.

It was the ninth straight victory for the 19-year-old Spaniard, who delighted a supportive South Florida crowd with his powerful strokes from the baseline and readiness to move forward, once again making use of his increasingly effective drop shot.

"I moved well and defended well and I counter-attacked and I think if I play at that same level I will have a lot of chances to get through," said Alcaraz.

"I feel at home here. It is easy to play here in Miami with all the energy I receive every day."

Tsitsipas had to wait a week for his first contest in Miami, beating Chilean Cristian Garin on Monday, but he came unstuck against Khachanov, losing 7-6 (7/4), 6-4.

In a clash of top-10 players, American Fritz defeated Denmark's Holger Rune 6-3, 6-4 to reach to the last eight in Miami for the first time in his career.

Fritz, who won at Delray Beach last month, beat Emilio Nava and Denis Shapovalov in straight sets before Tuesday's encounter and he was pleased with the way he was able to go on the attack.

"I couldn't play aggressively in my first two matches because my opponents were hitting every ball as hard as they could. (Rune) still crushes the ball but it was nice to feel I had some more time," Fritz said.

"The first two rounds, it was impossible to play my game, I just had to make balls. Today when I got the chance to be aggressive I was and I just wanted to serve well and try not to give him many free points."

Italian Jannick Sinner also advanced to the last eight without dropping a set and he was in firm control from the outset against Russian sixth seed Andrey Rublev, winning 6-2, 6-4.

Sinner, who has never failed to reach the quarters in his three appearances in Miami, will face Finland's Emil Ruusuvuori after he beat Dutchman Botic van de Zandschulp 4-6, 6-4, 7-5.

Ruusuvuori was facing an exit after trailed by a break in the second set but from 4-3 down he won three straight games.

In the final set, the Finn grabbed the decisive break when 6-5 up in the third set to reach the last eight for the first time in this event.
