Miho Koga benefited from another late meltdown by Yuri Fudo to successfully defend the season-ending Japan LPGA Tour Championship on Sunday, clinching the money rankings title in the process.

Koga overturned a five-shot deficit to beat Fudo by two shots here last year and the 26-year-old was unable to conceal her shock as Fudo lost the plot again on the 18th to hand Koga her fourth title of the season.

Koga leapfrogged South Korean Lee Ji Hee and Sakura Yokomine to finish top of the money list for the first time after a 4-under-par 68 saw her win the 11th tournament of her career with a 6-under 282 total.
