Please can you explain the new dropping procedure?
When dropping the player may use the original or another ball. Only the player can drop the ball in singles (but in foursomes and four-ball a partner may also drop the ball). Drop straight down from knee height, as shown in the picture, without throwing, spinning or rolling. Ball must strike the ground in the Relief Area and be played from the Relief Area. If you forget and drop from shoulder height correct the error before you hit your shot or you will be penalised a stroke.
Note: 'Knee height' means the height of a player's knee when in a standing position.
