Lydia Ko's turned on the sizzle to be in a commanding position after the second round of the LPGA's season ending championship in Florida.
The world number one has shot a course record 62 to be 12 under for the tournament and three clear at the halfway point.
Ko spent a late night on the range with her coach after the first round tweaking things.
"Going into today I just wanted to focus on my game and I knew I had a great pairing.... and maybe it was the great vibes I got from them but obviously it's a great round and I'm in a better position than I ever could have imagined," said KO. "Over the weekend I just have to focus on me."
Tim Wilkinson and Steven Alker have both dropped down the leaderboard in their second rounds at the PGA Tour in Georgia.
