South Korean female golfer Yoo Hyun-jo has jumped to the solo lead with an unstoppable "birdie show."

This week's tournament is the only one on the KLPGA Tour played under the modified Stableford format.

In this scoring system, an eagle is worth 5 points, a birdie 2 points, and a bogey deducts 1 point.

Starting with the very first hole in the second round today (October 9), Yoo racked up seven birdies on the front nine alone, including five consecutive ones, and added four more birdies on the back nine.

From her shots to her putts, it was literally her day.

Pocketing an impressive 11 birdies without a single bogey to add 22 points, Yoo climbed to the solo lead by a 1-point margin.

Under a standard stroke play format, that would mean carding an 11-under 61 for the day.

Yoo, last year's grand prize winner, is eyeing her second win of the season and her fourth career victory.
