Wentworth, United Kingdom: South Korea's Byeong-hun An was hunting down the biggest win of his professional career as the final round of the European PGA Championship got underway at Wentworth on Sunday.

An, the US Amateur winner in 2009, shared the third-round lead with Italy's Francesco Molinari but after three holes of his final round had opened up a one-shot lead over Thailand's Thongchai Jaidee. The 23-year old Korean had a birdie two at the second whilst Molinari, who has led since the first round, dropped a shot at the first. Molinari slipped up when he missed the green with his approach and played a sloppy chip up to 25 feet but An holed a decent four-footer to go a shot ahead.
