(Reuters) - First-round leader Jang Ha-na fired a bogey-free four-under 67 to extend her lead at the Marathon Classic to two strokes midway through Friday's second round, which was delayed over two hours due to wet conditions.
LPGA Tour rookie Jang, still bothered by a back injury that has her finishing her golf swing with one arm, was ready to roll after the delayed start.
The 23-year-old South Korean, who led by one overnight, posted birdies on her first two holes and two more on her second nine, crowned by a 10-foot birdie at the ninth, her last hole of the day.
