"The Nitto ATP Finals is reserved for the best and qualifying for a 14th time reflects the excellence he brings, year after year.
"We look forward to witnessing him continue to chase history in Turin."
Stefanos Tsitsipas is currently in second position in the race to Turin, with Matteo Berrettini, Andrey Rublev, Alexander Zverev, Daniil Medvedev, and Rafael Nadal all well positioned to qualify too.
