The PGA Tour returns to the U.S. this week for the Shriners Hospitals for Children Open. Here's a quick look at some marquee early-round groupings in Las Vegas (all times ET):
Piercy is a Vegas resident and is already making his fourth start of the new wraparound season, which he began with a T-3 finish at the Safeway Open. He'll be joined by Koepka, whose last States-side performance came at the Ryder Cup, and Horschel, a former FedEx Cup champ who hasn't teed it up since the BMW Championship in September.
