(Reuters) - New Zealand teenager Lydia Ko knows full well that she will face a formidable challenge next year in trying to replicate, at the very least, her astonishingly successful rookie campaign on the LPGA Tour.

The 17-year-old capped a storming 2014 season by clinching her third victory in a gripping three-way playoff for the Tour Championship on Sunday at Tiburon Golf Club in Naples, Florida.
