NAPLES, Fla. — New Zealand teenager Lydia Ko ended a big year on the LPGA Tour with the largest payoff in women’s golf.

Ko won the $1 million bonus from the Race to CME Globe on Sunday even before she began a three-way playoff. The 17-year-old added $500,000 when she defeated Carlota Ciganda of Spain on the fourth extra hole at Tiburon Golf Club.

Ko played the 18th hole five times Sunday and made par each time. The last par gave Ko her third victory of the year.

Meanwhile, Stacy Lewis became the first American in 21 years to sweep the three biggest awards on the LPGA Tour.

Lewis closed with a 1-under 71, good enough for her to win the points-based player of the year award for the second time in three years. Lewis also won the Vare Trophy for the lowest scoring average and the money title.
