Simon Dalton presents his prediction for the ATP Finals match.
Jannik Sinner has already secured his place in the semi-finals after two straight-sets victories, while Ben Shelton is out of contention following two defeats. The Italian is expected to claim a third consecutive win, whereas the American will try to bow out with pride.
Jannik Sinner
This season, Sinner has captured titles at the Australian Open, Wimbledon and Paris. Indoors, he has been unstoppable — 28 consecutive wins on hard courts under a roof since 2024. Remarkably, he has won 14 of his last 15 indoor matches in straight sets, dropping just one set to Alexander Zverev in Vienna. At the ATP Finals, he has continued to dominate — Felix Auger-Aliassime fell by seven games (7:5, 6:1), while Zverev lost by five (6:4, 6:3). Against Ben Shelton, Sinner holds a perfect record: seven victories in a row without dropping a set, including three this year alone.
Ben Shelton
Shelton’s debut at the season-ending tournament has been disappointing — losses to Alexander Zverev (3:6, 6:7) and Felix Auger-Aliassime (6:4, 6:7, 5:7) have sealed his fate. His record against top-10 players remains poor, with nine defeats in his last ten encounters. Since injuring his shoulder after the US Open, his rhythm has been disrupted, and his current indoor record stands at 4-5, marked by unforced errors in long rallies. With no motivation left and facing an opponent of Jannik Sinner’s calibre, his chances are slim.
Jannik Sinner vs Ben Shelton Prediction
Sinner is likely to dictate the pace from the first games, using his return and relentless pressure to neutralise Shelton’s serve. The American may pick up points through aces, but his losing streak in this head-to-head looks set to continue. Expect another confident, one-sided performance from the Italian.
