Jang Ha-na claimed her second LPGA Tour crown after romping to victory at the HSBC Women's Champions.

A final-round 65 saw South Korea's Jang to a comprehensive four-stroke win at the Sentosa Golf Club in Singapore on Sunday.

Jang, who claimed her maiden title at the Coates Golf Championship last month, closed out the tournament with an eagle to finish 19 under through 72 holes.

Thailand's Pornanong Phatlum was runner-up to the 23-year-old following her four-under-par 68.

Amy Yang (71) of South Korea finished third at 11 under.

Candie Kung (69), Ariya Jutanugarn (70), Chella Choi (70), Choi Yeon-na (70) and Mirim Lee (72) were a stroke further back in a tie for fourth spot.

Meanwhile, 2015 champion Inbee Park (69) finished 16 shots behind Jang.
