Final-round play in the 107th PGA Championship from Quail Hollow Club in Charlotte, N.C. Xander Schauffele's victory in this major last year was the ninth straight PGA won by an American, with Jason Day being the last international winner in 2015. A tie after 72 holes would be settled in a three-hole playoff on this George Cobb-designed course that also hosted the 2017 PGA, won by Justin Thomas at 8-under-par.
