Defending champion Nick Dunlap, who won the 2024 American Express as a PGA Tour rookie, will try to become the first back-to-back winner of the event since Johnny Miller in 1975-76.

There's plenty of star power near the top of the leaderboard at the American Express through 54 holes — Jason Day (19 under), Patrick Cantlay (18 under), Justin Thomas (17 under), just to name a few — but there are also nearly a dozen notable names who are packing their bags early after missing the cut on Saturday afternoon.

William Mouw paid the price for going in the San Andreas Fault bunker at the par-5 16th hole at the Stadium Course at PGA West.

The 35-year-old Tour veteran would join a long list of players who won their first event here in the California desert.
