BUSAN, South Korea (AP) — Jin Young Ko missed extending an LPGA Tour scoring record in the rain while her South Korean compatriots packed the first round leaderboard of the BMW Ladies Championship in Busan. Ko had 14 straight rounds in the 60s. That tied her with Annika Sorenstam and So Yeon Ryu for the most in tour history. But Ko finished with a 1-under 71 after a birdie on the 18th hole at LPGA International Busan. Ko was seven strokes behind leader Na Rin An’s 64.
