Jannik Sinner, 23, Italy

Seed: 1

Best ATP Finals performance: Runner-up (2023)

2024 titles: 7 (Australian Open, Rotterdam, Miami, Halle, Cincinnati, US Open, Shanghai)

2024 win-loss: 65-6

Sinner, whose unassuming personality contrasts with his ferocious hitting, landed his first major title in Melbourne as he lost just once going into April. Shock news arrived in August that he had failed two doping tests but he was allowed to continue playing as an independent panel accepted there was “no fault or negligence” on his part. He went on to win the US Open and has been beaten only once in his past 23 matches.

Daniil Medvedev, 28, Russia

Seed: 4

Best ATP Finals performance: Winner (2020)

2024 titles: 0

2024 win-loss: 45-19

While far from his best season, Medvedev continues to challenge when it comes to the biggest prizes. Beaten in the Australian Open final, he also reached the Wimbledon semi-finals and US Open quarter-finals. His consistency, despite not winning a title this year, was enough to reach the Finals for a sixth straight season.

Taylor Fritz, 27, United States

Seed: 5

Best ATP Finals performance: Semi-finals (2022)

2024 titles: 2 (Delray Beach, Eastbourne)

2024 win-loss: 49-21

What has stood out about Fritz’s season is the high level he has produced across all surfaces. He has contested ATP finals on hard, grass and clay courts, including his first Grand Slam final at the US Open.

Alex de Minaur, 25, Australia

Seed: 7

Best ATP Finals performance: Debut

2024 titles: 2 (Acapulco, ‘s-Hertogenbosch)

2024 win-loss: 47-16

De Minaur’s dedication to his craft has reaped even greater rewards this year. Two tour titles, plus three consecutive Grand Slam quarter-final appearances at the French Open, Wimbledon and US Open, have led to a year-end top-10 finish for the first time.
