Felix Auger-Aliassime emerged victorious over fellow Canadian Gabriel Diallo with a 6-2, 7-5 win in a Montreal showdown at the Swiss Indoors in Basel. The fifth seed showcased his skill with eight aces and capitalized on four breaks to secure the win. Diallo, matching Auger-Aliassime’s eight aces, struggled to win only 35% of his second-serve points.
Auger-Aliassime, a two-time Basel champion in 2022 and 2023, will now face Croatian qualifier Marin Cilic in the Round of 16 at the ATP 500 event on Thursday. Joining him is Denis Shapovalov from Richmond Hill, Ont., who advanced on Tuesday with a hard-fought three-set victory over American Marcos Giron. Shapovalov is set to compete against France’s Valentin Royer, a lucky loser whom he previously defeated at the U.S. Open earlier this year.
