Friday’s RR3 at the BNP Paribas WTA Finals Singapore presented by SC Global was significantly shorter than previous rounds, as Sloane Stephens and Kiki Bertens moved into the semifinals with their two matches together lasting less than two and a half hours.
The fifth-seeded Stephens tops the Red Group with perfect 3-0 record in round-robin stage on her tournament debut. Today the American defeated top seed Angelique Kerber 6-3 6-3, which is her fifth consecutive straight-set victory over the German. The top-seeded Kerber won just 33% of points on second serve and converted only two out of 10 break points, including zero out of seven at the start of the match.
