Jannik Sinner has secured a spot in the semifinals of the ATP Finals, becoming the first player to do so after Taylor Fritz defeated Alex de Minaur 5-7, 6-4, 6-3. Sinner's advancement was guaranteed despite his upcoming match against Daniil Medvedev, who still has a chance to qualify for the semifinals if he wins. Meanwhile, Fritz, who also has two wins, awaits the outcome of the Sinner-Medvedev match to determine his fate in the tournament. De Minaur was eliminated from the competition, having failed to secure any wins in his debut. Sinner seeks his first Finals title this year after winning seven tournaments, including the French Open and Wimbledon. Alexander Zverev leads the other group, with Casper Ruud, Carlos Alcaraz, and Andrey Rublev also in contention.
