New Zealand golfer Lydia Ko has climbed to within four shots of the lead following an improved second round at the Thailand LPGA.
Ko improved 14 places at the $1.8 million event in Chonburi courtesy of a two-under 70 to follow her opening-round 72.
The 16-year-old is among seven golfers on two-under, four shots behind outright leader Sweden's Anna Nordqvist on six under.
World No.4 Ko climbed inside the top-10 after shooting four birdies but bogeys on the 16th and 17th pegged her back.
