The demanding layout at Aronimink Golf Club, with its lengthy and well-protected par-3 holes, underpins the market's strong lean toward no hole in one occurring during the PGA Championship. Most of the par threes play well over 180 yards, featuring firm greens, tight pin placements, and variable winds that limit precision on tee shots. Historical patterns at the event show aces appearing only sporadically, often zero or one across four rounds, even with a deep field of top professionals. Recent rounds have produced several near-misses on those holes without resulting in aces, reinforcing trader consensus around the setup's elevated barriers compared to more accessible major venues.
