Swiss Indoors Basel - Basel

An ATP 500 played indoors on hard in Basel, in the autumn run with Vienna and Paris still to come. The GreenSet court is genuinely fast and the serve dictates: holds sit at 84%, aces come freely and better than a third of sets reach a tiebreak. That lifts games totals and suppresses upsets. Federer won six titles here and Auger-Aliassime two, which fixes the type.
