Final-round play in the 108th PGA Championship from Aronimink GC in Newtown Square, Pa. Scottie Scheffler hoisted The Wanamaker Trophy for the first time last year after rolling to a five-shot win at Quail Hollow. A three-hole aggregate playoff format is used if players are tied after 72 holes. This par-70 Donald Ross course also hosted the 1962 PGA (won by Gary Player). Signature holes include two downhill par-3's (No. 5, No. 8) and the uphill par-4 18th.
