BEIJING - Australia's Minjee Lee beat back stiff competition from rivals to land her third LPGA victory at the Blue Bay tournament on China's Hainan Island Sunday. Lee carded a two-under par 70 to win by one stroke at 13-under par, one ahead of Jessica Korda and two ahead of Thailand's Ariya Jutanugarn on the par-72 course. Lee and Korda shared the leaderboard top spot heading into the final round, but the 20-year-old from Perth edged ahead of the American Sunday, firing a birdie at the first hole.  At the par-three seventh hole a birdie by Lee and a bogey by Korda extended that lead to three and the Australian closed out the tournament with rounds of 65-67-73-70 for a total of 275. Lee is projected to move up in the Rolex Women's World Golf rankings after her Blue Bay win.
