Ko set to fall

Lydia Ko is set to drop out of the top two in the women’s golf world rankings for the first time in more than two years. The 20-year-old Kiwi had a quiet final round at the Arkansas Championship on the LPGA Tour yesterday, carding a threeunder 68 to finish in a tie for 25th. She was 10 shots behind the winner, So Yeon Ryu.
