Elsewhere in the men’s draw, Britain’s Jack Draper suffered a 6-1 7-5 defeat by Poland’s Hubert Hurkacz.
Draper, 22, started slowly and was punished by the world number nine, who clinched the first set with ease.
Draper fought back in the second but a double fault allowed Hurkacz to serve for the match and wrap up victory inside 77 minutes.
In the women’s draw, two-time Grand Slam champion Aryna Sabalenka reached the third round with a hard-fought 6-4 3-6 6-3 win over Poland’s Magda Linette.
Kazakhstan’s former Wimbledon champion Elena Rybakina, fresh from beating Iga Swiatek on the way to last week’s Stuttgart title, was a 6-4 6-3 winner against Italian Lucia Bronzetti.
Britain’s Katie Boulter faces American Robin Montgomery later on Friday and victory would see her face Sabalenka in the next round.
