No. 4 (Par 5, 607 yards) 

Brooks Koepka calls Harding Park a “big-boy golf course,” and there is no bigger hole than this true 3-shotter for the vast majority of field. With two of the usual par 5s (Nos. 9 and 12) converted to long par 4s for the PGA, the 562-yard 10th hole serves as the only reasonably reachable scoring opportunity. But the long dogleg left fourth will take more work to walk away with birdie. Overhanging Cypress trees guard the corner off the tee and it requires a solid ball-striking gameplan to negotiate properly to set up the best approach angle to bring birdie into play.
