The first full-field event of the year kicks off Thursday with the Sony Open in Hawaii. Here are four groups to keep an eye on at Waialae Country Club, where Jimmy Walker looks to complete a three-peat (all times ET):
12:50 p.m. Thursday, 5:30 p.m. Friday: Justin Thomas, Emiliano Grillo, Danny Lee
This trio includes three players who broke through for their maiden victories last season, as all three will make their Masters debuts this spring. At No. 31, Grillo is the top-ranked player after his season-opening victory, but Thomas is not far behind and Lee is getting back to work after a season that saw him make 36 starts en route to spots at both the Tour Championship and Presidents Cup.
