Also joining Immelman as assistants at Quail Hollow Club in Charlotte, N.C., over Sept. 20-25 are Canada’s Mike Weir, Korea’s K.J. Choi and Australia’s Geoff Ogilvy. It will mark the first time as a captain’s assistant for the 40-year-old Villegas, who has made one Presidents Cup appearance (2009, TPC Harding Park). “Although it has been over 10 years since I played the event, I still have fond memories that are unforgettable, so joining on the other side as a captain’s assistant will be a highlight of my career,” the four-time Tour winner said in a statement. Villegas is making his seventh starts in the Zurich Classic, where his best finish is a T-14 in 2017 with Morgan Hoffmann. On the season, Villegas has made seven cuts in 14 starts with a best result of T-33 at the American Express. He recently finished T-59 at the RBC Heritage.
