Nov 18 (Reuters) - After a dose of positive reinforcement, Lydia Ko aced her second round at the season-ending CME Group Tour Championship with a tournament record 62 that catapulted her into a three-shot lead in Naples, Florida, on Friday.
Ko was seen working into the night on Thursday with instructor David Leadbetter after carding an opening 70 that left her four strokes behind pace-setter Shanshan Feng of China.
The 19-year-old New Zealander said a video he showed her of her first career hole-in-one at the Olympics in Rio sparked her 10-under-par round on Friday at Tiburon Golf Club.
