Jannik Sinner begins today his title defence of the ATP Finals against Félix Auger-Aliassime, the 25-year-old Canadian player who qualified for final competition of the year, as the eighth of the best eight players of the season. The bronze Olympic medallist in Paris, who had a career best rank of 6 in 2022, fell out of the top 20 due to injuries but climbed back in a spectacular 2025 with three titles ATP 250 and two more finals, the last one in Paris Masters earlier this month.
There, Auger-Aliassime lost to Jannik Sinner in straight sets, it was closer than ever: 6-4, 7-6(4). The Canadian said that he doesn't feel there's a "huge gap" with the World No. 1 and "I'm getting closer every match we play against each other" (via ATP.com), remembering how he managed to win a set at the US Open.
Felix Auger-Aliassime already managed to beat Sinner twice, but both of those times came in 2022. Sinner won their other three matches, all of them in 2025.
