R&A and USGA recently issued some “Clarifications” to the 2019-Rules of Golf.
These “Clarifications” covers different aspects, such as:
- Status of a players tee.
- Clarifications about embedded ball.
- When a caddie is allowed to lift the ball.
- Meaning of “Club-Length”.
- Model Local Rules.
Most of the Clarifications will probably not influence many players.
