(Reuters) - A sizzling career-low back-nine 29, that included a birdie-eagle finish, propelled South Korean Na Yeon Choi to the lead with 18 holes to play at the Walmart NW Arkansas Championship.
Her outstanding six-under back nine left her with an eight-under 63 for a tournament record 36-hole total of 13-under, two shots better than compatriot Mi Jung Hur, who shot 68 and is tied for second with Sweden's Anna Nordqvist (66).
The South Korean duo were tied for the lead with one hole remaining but Choi surged ahead at the par-five 18th when she hit a second-shot three wood to 45 feet from the hole and made the putt for a dramatic finish to her round.
