TURIN, Italy — Top-ranked Jannik Sinner became the first player to advance to the semifinals at the ATP Finals on Thursday.
Sinner was assured of a spot in the last four after US Open finalist Taylor Fritz beat Alex de Minaur 5-7, 6-4, 6-3 in their group.
Sinner won his opening two matches and plays Daniil Medvedev later Thursday. Last year, Sinner lost the final to Novak Djokovic, who is not playing this year due to injury.
Fritz also has two wins, while Medvedev is still in contention and could get to two wins by beating Sinner. De Minaur was mathematically eliminated without any wins in his finals debut.
The top two finishers in each group advance to the semifinals.
Alexander Zverev leads the other group ahead of Casper Ruud, Carlos Alcaraz and Andrey Rublev.
