Carlos Alcaraz swept past qualifier Andrea Vavassori to reach the quarter-finals of the ABN AMRO Open in Rotterdam.

World number three and top seed Alcaraz needed just over an hour to defeat Italian doubles specialist Vavassori 6-2 6-1 and continue his hunt for a first indoor trophy.

It was a much improved display from the Spaniard, who had been taken to three sets by home wildcard Botic van de Zandschulp in the first round.

"Every time that I leave the court, I'm always thinking how I can be better. That's what happened after the first round," Alcaraz said, quoted on the ATP Tour website.

"I just tried to be focused on the things that I had to improve from the first round - not making too many mistakes, not having too many ups and downs in the match, if I'm a break up, just to keep going with the same intensity.

"That is what I tried today, I think what I did was pretty good. After these types of matches, my confidence goes up."

Alcaraz will next play fellow Spaniard Pedro Martinez, who upset fifth seed Holger Rune 6-4 6-1 for a first victory over a top-20 player on hard courts.

Earlier on Thursday, third seed Alex de Minaur, last year's beaten finalist, did not face a break point as he saw off Jakub Mensik 6-4 6-4.

The Australian will next face lucky loser Daniel Altmaier, who beat world number 19 Arthur Fils in three sets, 4-6 3-6 7-5.

Andrey Rublev, the 2021 champion, booked a sixth quarter-final in Rotterdam after defeating Fabian Marozsan 7-6 (2) 7-6 (7) and will play Hubert Hurkacz in the last eight.

Sixth seed Stefanos Tsitsipas came from behind to end the run of home favourite Tallon Griekspoor, recovering after losing the first set to win 6-7 (5) 7-6 (6) 7-5.

World number 12 Tsitsipas goes on to meet qualifier Mattia Bellucci, who upset Daniil Medvedev in the last round.
