Tennis-Bertens rolls past Siniakova into last 16

Bertens was especially impressive on serve, landing 81% of her first serves in the first set, allowing Siniakova few opportunities to get into the match.

Dutchwoman Kiki Bertens showed no ill-effects from her brutal French Open campaign as she eased into the last 16 with a routine 6-2 6-2 win over Katerina Siniakova on Friday. Fifth seed Bertens saved a match point and was overcome by cramps after her win against Sara Errani on Wednesday, leaving the court in agony seated in a wheelchair.

She had also struggled past Katarina Zavatska in round one and had spent more than five hours on court, so was grateful as she rolled past a error-prone Sinialova in 58 minutes. Bertens was especially impressive on serve, landing 81% of her first serves in the first set, allowing Siniakova few opportunities to get into the match.
