American Taylor Fritz became the fifth player to book his spot in the eight-man ATP Finals in Turin after last week’s Paris Masters.
Fritz joins already-qualified Jannik Sinner, Alexander Zverev, Carlos Alcaraz and Daniil Medvedev for the event in northern Italy from 10-17 November.
Novak Djokovic, the two-time ATP Finals defending champion, missed the Paris Masters but remains in the running in sixth spot.
Fritz, 27, was eliminated in the second round in Paris by British No 1 Jack Draper.
