Y.E. Yang has overtaken Liang Wenchong at the top of the OneAsia Order of Merit following his sensational win at the 53rd Kolon Korea Open at Woo Jeong Hills Country Club.

Yang earned US$262,430 for his dramatic, come-from-behind victory in Cheonan, which marked his second win on OneAsia after his imperious display at the Volvo China Open in April.

The 38-year-old, who became Asia's first Major winner at last year's PGA Championship, leapfrogged Liang to the top of the OneAsia money list with earnings of US$679,090 following his second winner's cheque of the year.

Yang also became the third player to win two OneAsia titles following Liang, who has three, and Bae Sang-moon, who won last year's Kolon Korea Open and the SK Telecom Open in May.

Liang is second on the OneAsia Order of Merit with US$493,200 after an impressive season in which he has won the Luxehills Chengdu Open and Thailand Open and finished runner-up in the Indonesia Open presented by Enjoy Jakarta.

This week the Chinese number one defends his title at the US$1 million Midea China Classic, where the winner will walk away with US$180,000.

Big-hitting Kim Dae-hyun, who won May's GS Caltex Maekyung Open, consolidated his third-place ranking with a joint-seventh finish at the Kolon Korea Open, which took his earnings to US$272,154.

Bae, Kim's good friend and a fellow Daegu resident, also tied for seventh at Woo Jeong Hills to jump two places to fifth with US$220,343. The 24-year-old is still behind New Zealander Michael Hendry, the Indonesia Open champion, who remains fourth with US$241,533.

This week's Midea China Classic is the eighth of 10 OneAsia events in 2010. The tournament purse has doubled to US$1 million on the OneAsia platform due to the continued sponsorship support from the Midea Group for the sixth consecutive year.

The Midea China Classic will be showcased on OneAsia's television platform with live coverage for four hours a day across all four tournament days, and broadcast to over 260 million homes in more than 40 countries.

Full coverage of the event is available internationally on ESPN Star Sports, Jupiter Golf Network, SBS Golf Channel, Fox International, Network Ten, Sky Sports NZ, ESPN3 and America One in the USA, ViaSat and Bloomberg Television among others in Europe.
