Angelique Kerber became the third player at Wimbledon this year to achieve the usually rare 'double bagel' as she beat fellow German Carina Witthoeft 6-0 6-0 on Tuesday.
Former semi-finalist Kerber is a solid grass-court performer and won the Aegon Classic title in Birmingham earlier this month.
Seeded 10th for Wimbledon, she followed Venus Williams and Andrea Petkovic, who both won without dropping a game on Monday, in making the most straightforward possible progress to the second round.
Before this tournament, there had not been a Wimbledon double bagel in the women's singles for six years.
