WTA Finals - Shenzhen

The season-ending WTA Finals, played indoors on hard in Riyadh at the close of the Asian swing. No wind, no sun, a true bounce and a quick, consistent ball, which rewards clean first-strike hitting. The serve is protected, so sets stay tight, tiebreak risk rises and games totals hold up better than at a grind-it-out venue. The returner has to manufacture from the baseline. Best of three.
