Omega, Official Patron of the PGA Championship, and its Ambassadors Rory McIlroy, Sergio Garcia and Tommy Fleetwood, celebrated the start of the 100th PGA Championship today by surprising unsuspecting bystanders with a 100-yard, golf-shot at the base of the famous Gateway Arch National Park. The trio each attempted shots from the shadows of the Gateway Arch National Park to see whose accuracy was dialed in from a tee positioned 100-yards away from the target - a traditional pin flag, which was placed under the Arch.
