Playing through torrential rain, In-Kyung Kim returned a second round of 68 at Kingsbarns Golf Links on Friday evening to take a two-stroke lead in the Ricoh Women’s British Open.

Kim went to the turn in one-under-par but eagled the long 11th to move one stroke clear of the clubhouse leaders, Georgia Hall and Lexi Thompson. She then birdied the par-4 17th during a particularly heavy downpour to extend her lead at the championship’s halfway stage.

The world number 21 claimed her sixth LPGA title a fortnight ago, a year after winning for the third time on the LET at the ISPS HANDA Ladies European Masters, in Germany.

She said: “I really didn’t know what I was shooting. I just wanted to play in my own time, because it was really hard, especially on the last three or four holes when it was pouring down. I just had to move forward.”

She added that her eagle on 11 was “unexpected”, as her drive ran downhill leaving her 206 yards to the front and she dribbled a 5-wood up to within 20 feet, before draining the putt.
