Justin Rose isn’t competing this week in Maui, and Brooks Koepka, the current No. 1, has his work cut out for him if he wants to retain this spot. Last year, Koepka finished last in the 34-player field at Kapalua, although he was dealing with a wrist injury at the time, and the tournament wound up being the last he would play for more than three months. His one other start in the Tournament of Champions, however, was more to his liking: a T-3 in 2016.
