World number three and top seed Alcaraz needed just over an hour to defeat Italian doubles specialist Vavassori 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.
After these types of matches, my confidence goes up. Alcaraz will next play fellow Spaniard Pedro Martinez, who upset fifth seed Holger Rune for a first victory over a top 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 The Australian will next face lucky loser Daniel Altmaier, who beat world number 19 Arthur Fils in three sets, Andrey Rublev, the champion, booked a sixth quarter-final in Rotterdam after defeating Fabian Marozsan 2 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 5 6 World number 12 Tsitsipas goes on to meet qualifier Mattia Bellucci, who upset Daniil Medvedev in the last round.
