Rory McIlroy (-16)won his third consecutive tournament and his second consecutive major, finishing the year with his second career PGA Championship. And his fourth career Major victory. What a year for Rory. Oh, and he finished this one in the dark. McIlroy, Bernd Wiesberger, Rickie Fowler and Phil Mickelson finished as a semi-foursome in the relative darkness as commentators freaked out and Twitter praised their heroic achievement of playing past dusk. Phil finished 2nd at -15.
