Heading into the final round at the CME Group Tour Championship, Lydia Ko trailed by three strokes, but she came from behind, shooting a final-round, bogey-free 68 to force a playoff. The 17-year-old from New Zealand and the youngest player in the star-studded field collected the largest payday in women’s golf history Sunday, winning the $1 million Race to the CME Globe and $500,000 tournament purse. Ko, who doesn’t even have her driver’s license yet, locked up the inaugural Race to the CME Globe in regulation, posting a tournament total of 10-under.
