London - Australian Open champion Angelique Kerber breezed into the Wimbledon quarter-finals with a straight sets victory over Japan's Misaki Doi on Monday.
The German fourth seed won 6-3, 6-1 on Court Two in a one-sided, 64-minute contest against the world number 49.
Kerber faces either fifth seed Simona Halep of Romania or US ninth seed Madison Keys in Tuesday's quarter-finals.
Doi was the first Japanese woman to reach the last 16 of any Grand Slam event since Ai Sugiyama made the Wimbledon fourth round in 2006.
