Felix Auger-Aliassime is a professional tennis player from Canada. He is the second-youngest player in the top 20 of the Association of Tennis Professionals (ATP), with a career-high singles ranking of No. 9 on January 10, 2022, and a career-high doubles ranking of No. 60 on November 1, 2021. On the ATP Tour, he has eight runner-up finishes in singles and one doubles title. At a young age, Auger-Aliassime began competing on the professional tour. At 14 years and 11 months old, he is the youngest player to win a main draw match on the ATP Challenger Tour, and he is one of only seven players to win a Challenger title by the age of 16.

At 17 years and one month, he is the second-youngest player to win multiple Challenger titles, and at 17 years and ten months, he is the youngest player to defend a Challenger title. Auger-Aliassime had a successful junior career, reaching No. 2 in the world and winning the boys’ singles title at the 2016 US Open. With compatriot Denis Shapovalov, he also won the boys’ doubles title at the 2015 US Open. Auger-Aliassime debuted in the top 100 and top 25 on the ATP Tour at the age of 18 in a year that culminated in his first ATP final in February 2019 at the Rio Open, an ATP 500 event.

Despite being 2 sets to love up, Auger-Aliassime lost in the fourth round of the 2021 Australian Open to Russian qualifier Aslan Karatsev. Toni Nadal, Rafael Nadal’s uncle and former coach, was hired as a new coach in April, just in time for the clay-court season. Auger-Aliassime was defeated in the first round of the French Open by Andreas Seppi. In the 2021 Stuttgart Open final, he lost to Marin Cilic for the eighth time (out of eight final appearances). He reached the semifinals of the Halle Open by shocking 10-time tournament champion, 5th seed, and childhood idol Roger Federer in the second round, securing his fourth Top-10 victory (4-15) and one of his career’s most significant victories.
