NEW YORK (AP) — Serena Williams started fast and finished strong to reach the quarterfinals by beating Kaia Kanepi 6-0, 4-6, 6-3.
Williams, seeded 17th, won the first set in just 18 minutes. She quickly seized control again after dropping the second, racing to a 3-0 lead in the final set.
The six-time U.S. Open champion, who missed the tournament last year and gave birth to her daughter during it, advanced to face 2016 finalist and No. 8 seed Karolina Pliskova.
Kanepi, the 44th-ranked Estonian who knocked out top-ranked Simona Halep, was trying to make her second straight U.S. Open quarterfinal.
