MILTON KEYNES, England — Ashleigh Buhai of South Africa shot a seven-under-par 65 and took a one-stroke lead in the first round of the Women’s British Open on Thursday.

Buhai finished just ahead of Hinako Shibuno of Japan and Danielle Kang of the United States, who each had a bogey in rounds of 66.

“In my last few tournaments, I’ve had three good rounds and one not so good round, so I’m hoping this is the week I can do four good rounds,” said Buhai, whose best finish this year was a tie for 11th. “The last few weeks, I have been just trying to stay mellow and keep everything in check, and it seems to be helping.”

Top-ranked Jin Young Ko, seeking her third major title of the year after winning last week’s Evian Championship in France, was well positioned after a 68.
