Golf Women's British Open

In Gee Chun of South Korea tees off on the third hole Friday in the second round of the Women’s British Open in Muirfield, Scotland.

MUIRFIELD, Scotland — In Gee Chun is making another strong run at a major.

The South Korean took the halfway lead at the Women’s British Open after a 5-under 66 in the second round Friday, putting her in position to challenge for a second major title of the year and fourth overall.

Chun was at 8 under, putting her one shot ahead of South Africa’s Ashleigh Buhai and Sweden’s Madelene Sagstrom, who both shot 65.

Seven-time major winner Inbee Park, also of South Korea, was another shot back after a 67.

Chun, who won the Women’s PGA Championship at Congressional in June despite consecutive weekend rounds of 75, carded six birdies and a solitary bogey in her round at Muirfield on Friday.

Sunday’s winner will earn more than $1 million, but Chun said she was also motivated by a slightly smaller cash prize on offer.

“Before the start of the tournament, my caddie and I talked about the course and after that we had a little bit of betting,” Chun said. “If I make a bogey-free round, he said he’s going to buy me dinner and pay me 100 dollars each day. So before each round, it’s like setting another goal. That mindset helped a lot on the course. I had two bogeys over the last two days but I want to keep trying to make a bogey-free round.”

Of Chun’s four LPGA Tour victories, three were at majors, including the 2016 Evian Championship and 2015 U.S. Women’s Open.

On Friday, she even got some help from one of the gusts of wind that make Scottish links golf so tricky.

“I have a great reason to love the Scottish wind now,” Chun said. “My ball was around the edge of the hole today and after like three seconds, it dropped. So now I can enjoy more the Scottish wind.”

Buhai looked on course to claim the halfway lead when she made an eagle and four birdies to make the turn in 30. But after another birdie on the 11th, she made only pars until her only bogey of the day on the last.

Overnight leader Hinako Shibuno followed her opening 65 with a 73 to fall four shots off the pace.

American Jessica Korda, who was second after the first round, settled for a 74 and was in a tie for 17th.
