Radius The distance between the center of the swing arc (the target or forward shoulder) and the hands on the grip. (Because of his unusually long arms, his swing had a large radius.)

Raised Swing Center Elevating the central area in the body (somewhere between the top of the spine and the center of the neck) around which rotation takes place. What the novice frequently refers to as "looking up" and results in a swing that is too high.

Rap To hit a putt with a short, firm stroke. (Former PGA Champion Gene Sarazen liked to rap his putts).

Reading the Green (or Putt) The entire process involved in judging the break and path of a putt. (Her caddie, Tom, was a genius at reading a green).

Recover To successfully hit a shot from a poor location. (Throughout his career, Arnold Palmer was known for his ability to boldly recover from trouble).

Release The act of freely returning the clubhead squarely to the ball at impact, producing a powerful shot. (Tiger Woods has a textbook release of the club at impact).

Reverse Weight Shift A swing flaw in which the weight moves forward on the backswing instead of to the back leg. (His reverse weight shift caused him to be a poor driver of the ball.).

Rhythm The coordination of movement during the golf swing or putting stroke. (For generations, Sam Snead's golf swing has been the model of perfect rhythm).

Road Hole The par-4 17th hole at the Old Course at St. Andrews, one of the most famous and difficult holes in the world. (His approach on the Road Hole missed the green and cost him the British Open).
