(Fixes typo in Jang's name in lead)
SINGAPORE, March 6 (Reuters) - Jang Ha-na stormed clear of the field on the back nine to register a four-shot victory at the HSBC Women's Champions on Sunday, the Korean closing with a seven-under-par 65 for a 19-under total to claim her second LPGA victory of the season.
Jang started the day with a one-stroke advantage but a hot putter carried her to a comfortable triumph over playing partner Pornanong Phatlum of Thailand, who scrambled brilliantly to stay in touch but was thwarted in her latest attempt to win on tour.
