Caddy On The Green

On The Green
When the player's golf ball lands on the green, the
caddie should be ready to hand him the putter. However,
this is not the only duty a caddie has on the green.

The Caddie whose player is first on the green tends the
pin, except when the golfer's shot was hit from the sand
trap. The other caddies should fix the ball marks with their
green repair tool, and move to just off the green close to
the following hole.

Keep very quiet while the players are putting, and stay
out of their line of sight-- in other words, do not stand
directly behind or in front of any golfer. Also avoid
walking in any golfer's line of putt, since a fresh footprint
could disturb the roll of the ball. When the sun is out, be
sure your shadow is not in the player's line of vision.
When tending the pin, hold the flag against the

flagstick, and keep it loose by holding it just above the cup.
Face the player who is putting, and pull the stick away
from the cup as soon as the ball is struck. Hold the pin off
the green by resting it on your toe or balancing it in the
rough around the green. Replace the pin neatly and quietly
when all the players are through.

Remember to NEVER set the golf bag or the edge of
the pin on the green, since this will make a permanent
indentation on it.
