Yuriko Lily Miyazaki

LONDON — Britain’s big day at Wimbledon got off to a rough start when wild-card entry Yuriko Lily Miyazaki won only 19 points en route to a 6-0, 6-0 loss to Daria Kasatkina on Thursday.

The 28-year-old Miyazaki committed 31 unforced errors and five double-faults in falling to the No. 14-seeded Kasatkina, a Russian who won the Eastbourne title ahead of the grass-court Grand Slam.

On Centre Court, Jacob Fearnley, a 22-year-old wild-card entry from Scotland, was playing seven-time champion Novak Djokovic.

In all-British second-round encounters on No. 1 Court, Katie Boulter faced Harriet Dart before Jack Draper faces Cameron Norrie.

Later on Centre Court, Andy Murray was set to play doubles with his brother, Jamie. The two-time Wimbledon champion pulled out of the singles competition.

Kasatkina will next face Paula Badosa, who advanced Thursday by beating Brenda Fruhvirtova 6-4, 6-2.

No. 12 Madison Keys marked U.S. Independence Day with a 6-2, 6-2 victory over Wang Yafan to reach the third round.

“I’ve always really loved playing during the Fourth of July. I think I’ve spent more Fourths of Julys in London than anywhere else in the world,” the 29-year-old American said. “It’s always fun, and it’s definitely an experience. Like today walking by I saw a bunch of Americans, and they all said, ‘Happy Fourth.’”
