Scottie Scheffler enters the final round of the PGA Championship at Aronimink Golf Club as the pre-tournament favorite to defend his title, yet recent round-by-round scoring has tightened the leaderboard among a deep field that includes Rory McIlroy, Cameron Young, Jon Rahm, and Ludvig Åberg. Young’s strong ball-striking and recent wins have kept him in contention, while McIlroy’s major experience and improved putting have supported his position near the top. Course conditions favoring accurate approach play and steady greens have rewarded consistent performers, with several players posting under-par rounds over the first three days to create a crowded top of the standings. Weekend momentum, including any late surges or bogey avoidance on the back nine, will determine final top-five placements in this second major of the season.
