Jannik Sinner qualifies for semis at ATP Finals while Taylor Fritz has to wait after beating De Minaur
Sinner won his opening two matches and plays Daniil Medvedev later. Last year, Sinner lost the final to Novak Djokovic, who pulled out injured this year. Fritz also has two wins, while Medvedev is still in contention and could get to two wins by beating Sinner.
