Nitto ATP Finals - London

The season-ending Nitto ATP Finals, played indoors on hard in Turin after the Paris and Stockholm weeks. A roof means the same bounce, light and ball every point, and the GreenSet court rates fast at 39.9 on the court pace index. Service games hold up and tight sets are settled in a tiebreak rather than a long grind. It suits a flat first-strike player who returns deep. Round robin, best of three.
