Scottie Scheffler and Rory McIlroy enter the final rounds at Aronimink Golf Club as the primary drivers of trader sentiment for PGA Championship top-five finishes, with Scheffler defending his title after opening as co-leader and McIlroy riding momentum from consecutive Masters wins. Cameron Young and Matt Fitzpatrick have climbed into the contender tier following strong 2026 form, including Young's Players Championship victory and Fitzpatrick's consistent results, while recent rounds have highlighted how course conditions at the par-70 layout reward precise iron play and putting. Head-to-head history favors the top-ranked players in major settings, though weekend momentum shifts from players like Chris Gotterup or Alex Smalley could create volatility in the top-five group. The wisdom of crowds reflected in current pricing accounts for these factors alongside potential late surges from the rest of the deep field.
