ORLANDO - South Korean rookie Jang Ha-Na fired a seven-under 65 to leap four shots clear of the field after the second round of the season-opening LPGA Tour's Coates Golf Championship on Thursday. The 22-year-old Jang completed 36 holes at 12-under-par 132 in the event which was suspended by darkness for the second straight day. Jang only qualified for the tournament on Saturday. "I had very nice iron shots today," said Jang, who has six victories on the Korean Tour. Jang's best shot of the day was a 25-foot putt on the final hole of the round that curled into the cup for a birdie. World No 3 Stacy Lewis posted a two-under 70 and she is alone in second place at eight under. Lydia Ko, the second-ranked player in the world, shot three-under 69 to move into a share of third place.
