ST. ANDREWS, United Kingdom (AFP) — World No. 1 Nelly Korda shot to the top of the leaderboard at eight under par on the second day of the women’s British Open at St. Andrews.

Korda won six times in seven starts on the LPGA Tour between January and May, including her second major at the Chevron Championship.

However, she failed to even make the cut at two of the last three majors since.

A bogey-free round of 68 took the American three strokes clear of defending champion Lilia Vu and Britain’s Charley Hull. The trio played together in a star-studded group on the opening two days.

Korda credited a change of putter for a turnaround in her form from the last couple of months.

“I just needed something different to look at. Sometimes you just need to switch it up,” she said after battling heavy wind and rain on Scotland’s east coast.

“I’m just trying to stay very present and not think about anything other than one shot at a time, and whatever golf and links golf throws at me, I’m going to take it head on.”
