ST ANDREWS (AFP) - A shaky finish tainted Park In Bee's first round at the Women's British Open on Thursday but a three under par 69 kept her bid for history alive at St Andrews.

Aiming to become the first golfer to win four Majors in one calendar year, the 25-year-old South Korean made a brilliant start at the Old Course with five birdies in a flawless outward half of 31 and she moved to six-under-par after another gain at the 10th.

But four dropped shots in five holes from the 13th rather spoiled the day before she picked up another birdie at the 18th.

The world No. 1 finished two strokes behind early pace-setter, Stacy Lewis, who boasted a great back-nine of 31 that was highlighted by five birdies, including a chip-in at the 15th.
