LAKE BUENA VISTA, Fla. – Lydia Ko could only think about the putts that didn't go in, perhaps because she was used to making so many.
Ko ran off four birdies on the front nine Saturday for a 30, and it was enough to carry her to a 5-under 66 and a share of the lead with Eun-Hee Ji going into the final round of the season-opening Diamond Resorts Tournament of Champions on the LPGA tour.
Ji also was hot early, and a pair of birdies early on the back nine gave her a 66.
They were at 13-under 200.
