Lauren Coughlin of the United States and Jenny Shin of South Korea card 6-under-par 66s on Thursday to take a one-stroke lead after the first round of the LPGA Tour’s Scottish Open at Dundonald Links. Shin, 33, starts her round on the 10th tee and records a birdie immediately. She then adds birdies at the 12th and 14th holes before finishing the round with another birdie on the 18th. That run of scoring puts her at 4-under for the turn. Both players’ 66s place them atop the leaderboard heading into the next stage of the tournament. In comments attributed to Shin, she emphasizes the importance of tee shots on the wind-swept course. With conditions described as challenging, the opening-round performance establishes an early advantage as the tournament continues.
