Carlos Alcaraz showed he was in fine physical form as he defeated Zizou Bergs of Belgium 6-4, 6-3 to advance to the quarterfinals of the Japan Open on Saturday in Tokyo.

Alcaraz, the top seed and World No. 1, credited his physio for helping him recover from a slight ankle injury suffered in the first round in Tokyo. The Spaniard needed just 79 minutes to move on in the hardcourt tournament and is seeking his eighth title of the 2025 season.

Awaiting Alcaraz in the quarterfinal is Brandon Nakashima, who defeated Hungary’s Marton Fucsovics 7-5, 6-3.

No. 3 seed Holger Rune of Denmark topped Ethan Quinn 6-4, 6-2 to set up a quarterfinal contest against Jenson Brooksby, another American. Brooksby defeated Italy’s Luciano Darderi 7-6 (7), 6-1.
