Defending champion Iga Swiatek overcame an early break to defeat Estonia's Anett Kontaveit and reach the French Open last 16 on Saturday. The eighth-seeded Pole won 7-6 (7/4), 6-0 to stretch her record of straight-sets victories at Roland Garros to 10 matches. Swiatek reeled off 11 of the last 13 games on Saturday and will face Ukraine's Marta Kostyuk for a place in the quarter-finals. "She had a fast start and I was late getting going," said Swiatek who had lost both her previous matches to Kontaveit. dj/mw
