British hopeful Heather Watson has an extra incentive to make the second week of a grand slam for the first time in her career after her coach pledged to shave his legs if she is successful.
The Guernsey star won 6-0 6-4 in a little over an hour to equal her best ever run at the Championships.
Watson will next face Victoria Azarenka after the Belarussian, back on tour after giving birth to her first child in December, ousted 15th-seeded Russian Elena Vesnina.
It also continues an encouraging upturn in results for Watson, who reached the semi-finals at Eastbourne last week following impressive wins over defending champion Dominika Cibulkova, as well as Barbora Strycova and Anastasia Pavlyuchenkova, ranked 23rd and 17th respectively.
Watson had a mid-season surge as she managed to reach the semifinals at the Aegon International, a Premier event, defeating many quality players to do so. It's always going to change.
While Watson stopped short of empathising too much with Bernard Tomic after his claim that he was bored during his first-round match, she has experienced her own struggles with motivation. So I had to stay calm and keep focusing on my game.
Watson ended the match with three successive breaks of serve to book her place in the last 32 in just 61 minutes. "More relaxed than in my first match". She successfully defended the US Open title 12 months later, adding the 2011 Australian Open title and rising to number one in the world rankings before halting her playing career. "I obviously know how she plays, she is a great player and was expecting and was prepared for the best. I'm going to watch Love Island".
