After teasing a pair of the marquee groupings this week at TPC Sawgrass, the PGA Tour released tee times for the full 144-man field on Monday. Here's a look at some of the early-round groups to keep an eye on as the top 50 in the world rankings all tee it up in the same event for the first time since the 2016 U.S. Open (all times ET):
8:05 a.m. Thursday, 1:30 p.m. Friday: Bubba Watson, Dustin Johnson, Brooks Koepka
Johnson has been world No. 1 since last February, but he'll need at least a top-11 finish this week to prevent Justin Thomas from assuming the top spot.
