TURIN, Italy — Jannik Sinner and Carlos Alcaraz are poised to add another entry into their rapidly developing rivalry when the ATP Finals open on Sunday without any of the Big Three for the first time in 23 years.
The top-ranked Sinner and No. 3 Alcaraz evenly split the year's Grand Slam titles between them with two apiece and it would be fitting if the pair meet again in Turin.
