Overview
- Carlos Alcaraz finished 2025 at 71-9 with eight titles, including Roland Garros and the US Open, and secured year-end No. 1 after going unbeaten in ATP Finals round-robin play.
- Jannik Sinner closed at 58-6 with titles including the Australian Open, Wimbledon and the ATP Finals, and together the pair accounted for the last eight Grand Slam trophies and a tour-leading 18 bagel sets in 2025.
- Peers and coaches such as Casper Ruud, Andrey Rublev and Patrick Mouratoglou say the duo combine pace, movement and complete skill sets, while cautioning that comparisons to the Big 3’s achievements remain premature.
- Rafael Nadal praised Alcaraz as “spectacular” but emphasized staying healthy, and Toni Nadal argued today’s field beyond Sinner is comparatively weaker, a view echoed by the current rankings gap to No. 3.
- Rising Brazilian Joao Fonseca credited practice time with Alcaraz as “really valuable” ahead of their Dec. 8 Miami Invitational exhibition, as insiders also criticize ATP marketing for over-prioritizing the rivalry at the expense of doubles.
