Kiwi golfer Lydia Ko has gone on the charge at the latest LPGA event in Indianapolis to take the lead.
The world number eight has carded an eight-under 64 to move to 15-under for the tournament, one clear.
Ko had just the one blemish in a round that had nine birdies including five straight on her back nine.
Ryan Fox is four back from the lead in a share of sixth at the European Masters in Switzerland.
