Top seed Carlos Alcaraz overpowered Italian qualifier Andrea Vavassori 6-2, 6-1 in just over an hour on Thursday in the second round of the ABN AMRO Open at Rotterdam, Netherlands.

The Spaniard, No. 3 in the ATP rankings, won 85 percent (22 of 26) of his first-serve points and saved his only break point while converting 5 of 8.

Alcaraz advances to the quarterfinals against Spain’s Pedro Martinez, who knocked off fifth-seeded Holger Rune of Denmark, 6-4, 6-1. Martinez was 4 of 8 on break-point opportunities to 1 of 2 for Rune.

Third-seeded Alex de Minaur of Australia overcame 12 aces by the Czech Republic’s Jakub Mensik — who also double-faulted five times — to win 6-4, 6-4. Fourth-seeded Andrey Rublev of Russia won a battle with Hungary’s Fabian Marozsan 7-6 (2), 7-6 (7). Sixth-seeded Stefanos Tsitsipas of Greece advanced, but seventh-seeded Arthur Fils of France fell to Germany’s Daniel Altmaier in three sets.

However, Spain’s Jaume Munar knocked off fourth-seeded American Ben Shelton, 6-2, 7-6 (3), and Japan’s Yoshihito Nishioka downed fifth-seeded Frances Tiafoe of the U.S. 3-6, 6-4, 6-3. Top seed Taylor Fritz faced Canada’s Denis Shapovalov in a late match.
