LONDON — Serena Williams earned her 600th career victory by brushing aside 42-year-old Kimiko Date-Krumm 6-2, 6-0 on Centre Court to reach the fourth round of Wimbledon on Saturday.

Date-Krumm was the oldest woman to reach the third round of Wimbledon in the Open era — having made the semifinals here in 1996 — and the Japanese veteran never stood a chance against the power game of the 31-year-old Williams.

Playing under the lights with the retractable roof closed on Centre Court in the last match of the day, Williams finished with 28 winners to 8 for Date-Krumm and broke her five times.

The five-time champion will next face Sabine Lisicki of Germany.
