Tennis
Our serve and return ratings for every player, built from historical serve and return statistics and adjusted for the strength of each opponent and for the surface. The player comparison adds up the serve and return counts of each main-draw match (men since 1991, women since 2007; tour level, Challenger and WTA 125): service points, first serves, break points, aces and double faults. We compute every percentage from those totals.
