Matteo Arnaldi is making his debut at the Intesa Sanpaolo Next Gen ATP Finals.
The 21-year-old has soared up the Pepperstone ATP Rankings the past two seasons, climbing nearly 900 places. The Italian won his first ATP Challenger Tour title this season in Italy and also reached Challenger finals in San Marino and France.
Arnaldi is one of three Italians in the field with fellow home favourites Lorenzo Musetti and Passaro also competing. The trio will try to join Jannik Sinner as Italian Intesa Sanpaolo Next Gen ATP Finals champions.
