Greenies are awarded to golfers who make a green in regulation and make par or better. If competing golfers both make a green in regulation, whoever is closer to the pin has the chance to win the greenie. Sandies are awarded to players who get up and down out of a bunker. In others words, they make par or better after hitting the ball in a bunker.
Betting on greenies and sandies may be available during certain PGA events.
