The 17-year-old New Zealand golf sensation Lydia Ko has officially become the youngest Rookie of the Year award winner in the history of the LPGA tour.
Ko has locked up the honor with three events remaining on the LPGA schedule thanks to a season highlighted by two wins, two seconds and nine other top-10 finishes.
Currently ranked number three in the world, Ko had already won two titles on the LPGA Tour as an amateur, and she's never missed a cut on the tour.
