South Korean Jang Ha-na picked up her second LPGA Tour win of the season in Singapore on Sunday.

Jang cruised to a four-stroke victory at HSBC Women's Champions at Sentosa Golf Club's Serapong Course, after a blistering final round of seven-under 65 took her to 19-under 269 for the tournament. Jang, who won the Coates Golf Championship last month for her maiden victory, is the first LPGA golfer to win twice in 2016, and took home US$225,000 in winner's check.

Pornanong Phatlum of Thailand was alone in second at 15-under, followed by South Korean Amy Yang at 11-under.

Jang began the round nursing a one-stroke lead over Phatlum at 12-under, but set the tone early with a birdie at the first hole.

She picked up two more birdies on the front nine.

Jang had her first hiccup with a bogey at the par-4 11th, but then strung together three consecutive birdies to open a four-stroke lead over Phatlum.

Jang closed out the victory in style with an eagle at the par-5 18th. She tied Karrie Webb for the low round of Sunday.

Jang, an LPGA sophomore, had four runner-up finishes in 2015. (Yonhap)
