The LPGA Tour season has now come to an end and was capped off with Lydia Ko's victory in the CME Group Tour Championship. This is the second time that the New Zealander has won this event, and it is especially the third time that she has won the LPGA Tour Order of Merit. This week in Florida, Lydia Ko is ahead of the Irish Leonna Maguire by one shot and the Swedish Anna Nordqvist by two shots. The victory still took time to take shape for the former world number 1, it was necessary to wait for holes 16 and 17 and two birdies, which allowed him to take a breath of fresh air before attacking his 72nd and last hole.
