The par-4 10th hole at Aronimink Golf Club stands out as the toughest on the course during the 2026 PGA Championship. With 18 holes left in Sunday’s final round and a crowded leaderboard, this 472-yard hole may shape the outcome. Its demanding green and hazards create major challenges for players.
The hole averages 0.386 strokes over par, making it the hardest on the layout according to PGA Tour statistics. Much of the difficulty comes from its green complex, which features severe undulations and limited flat spots for approach shots and putts. Golf analyst Smylie Kaufman described it during an episode of The Smylie Show as “probably the most difficult green that some of these players are going to play in their career.”
