With a swing as repeatable as a metronome and on plane as a flight attendant, Louis Oosthuizen dominated the field with a seven-shot victory at the Open Championship. One of the reasons for his Tiger-like performance was how close he hit his irons on St. Andrews’ enormous greens.

His weapon of choice: Ping’s new S56 iron. The key to the iron’s success in the strong winds that buffeted the OId Course all four days is its penetrating trajectory thanks to a variable position tungsten toe weight that lowers the ball flight in the short irons. The blade-style iron also has a patent-pending “Stabilizing Bar” that varies in width throughout the set to optimize each individual iron’s center of gravity location for further flight-control enhancement.

Not to be confused with the company’s similar-looking S57 iron, which has a thermoplastic urethane insert in the rear pocket cavity, the S56 will be in stores by mid-September.
