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 he wrapped up victory inside 77 minutes.

Seventh seed Andrey Rublev made his way into the third round with a straight-set win over Facundo Bagnis, fourth seed Alexander Zverev beat Borna Coric 6-2 6-3, while Denmark's Holger Rune also progressed with victory over Mariano Navone.

In the women's draw, Britain's Katie Boulter lost 1-6 6-3 6-4 to American wildcard Robin Montgomery.

Meanwhile two-time Grand Slam champion Aryna Sabalenka earned a hard-fought 6-4 3-6 6-3 win over Poland's Magda Linette, setting up a third-round meeting with Montgomery.

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.
