The PGA Championship 2026 heads towards its conclusion with Round 4 beginning on Sunday morning at Aronimink Golf Club in Newtown Square, Pa. Alex Smalley nailed a birdie on 18 and three during his final four holes in Round 3 to get to 6 under for the tournament, putting him up two shots on the rest of the field. Some big names are chasing him, however, with Ludvig Aberg (-4), Jon Rahm (-4), Rory McIlroy (-3) and Xander Schauffele (-3) all within three strokes of the lead. Defending champion Scottie Scheffler is at 1 under for the tournament. 

Smalley is the +480 favorite (risk $100 to win $480) in the 2026 PGA Championship odds heading into Sunday, followed by Rahm (+500), Aberg (+600) and McIlroy (+700).

2026 PGA Championship Sunday predictions 

One major surprise the model is calling for at the PGA Championship 2026 Sunday: It projects that Smalley finishes outside the top 5 despite carrying the two-shot lead into Round 4. He's defied the odds all weekend, shooting 67-69-68 thus far. It's been an admirable effort, but he's got a loaded leaderboard ready to pounce. His lack of experience with this type of pressure makes him a tough favorite to back, according to the model. See who else to fade here. 

Another surprise: The model projects a bounce-back Sunday for Scheffler, as he is projected to get back in the top 5 despite entering Sunday at T23. He's now fired back-to-back rounds of 71, though he did shoot a first-round 67. Scheffler leads the PGA this season with a fourth-round scoring average of 67.22, so the model loves his value for outright bets at +1600, and makes him a strong play for top-5 bets (+230). See who else to pick here.
