Line of the ball
The most basic concept in the sport of polo is the line of the ball a right of way established by the path of a traveling ball.
When a player has the line of the ball on their right, they have the right of way. This can be taken away by moving the player off the line of the ball by making shoulder-to-shoulder contact.
A player can:
hook an opponent’s mallet,
push them off the line,
bump them with their horse
or steal the ball from them.
The umpires’ primary concerns are right of way and the line of the ball.
The line of the ball is an imaginary line that is formed each time the ball is struck. Similar to the line when you’re driving your car on a road.
This line traces the ball’s path and extends past the ball along that trajectory.
The player who last struck the ball is considered to have right of way, and no other player may cross the line of the ball in front of that player. Riding alongside to block or hook is allowed, as long as the player with right of way is not impeded.
Bumping or riding off is allowed as long as the angle of attack is less than 45 degrees, and any contact must be made between the pony’s hip and shoulder.
A player may hook or block another player’s mallet with their mallet, but no deliberate contact between players is allowed.
The Mallet may only be held in the right hand.
Ponies play for a maximum of two Chukkers per match.
