Rule 27. Line of the Ball

Blue Book 2026, Part 1, Rule 27 · Precedence and Personal Fouls
In plain English
The line of the ball is the track it is travelling on, extended.
- The line of the ball is the extended path the ball has travelled or is travelling on. It counts just the same when the ball came off a pony, off a player, off the umpire's pony or off anything else on the field, so a deflection makes a new line at once.
- Miss the ball at a free hit and the line becomes the direction you were riding.
- The line is what decides precedence between players, and the rule then works down a ladder.
- Two opponents both exactly on the line and making a play on each other, following or meeting, beat everybody else.
- Otherwise a player exactly on the line with the ball on their offside, following or meeting, has it - except against that pair.
- Nobody may enter in front of the player on the line unless the speed and distance leave not the slightest risk. A player who does enter safely and takes control of the ball may not then be ridden into from behind.
- With nobody exactly on the line, and two or more riding the same general way, the smaller angle to the line wins; at equal angles, the one with the line on their offside.
- Riding the way the ball is going beats riding against it, unless the pair at the top of the ladder are involved.
- Hitting the ball last earns you nothing if you have since come off the exact line.
- At a throw-in nobody has precedence until the ball leaves the line out, thrown or hit away; until then any angle is allowed so long as it is not dangerous.
- You may not play the ball on your nearside if doing so endangers a player who could otherwise have made a legitimate play.
The clause that governs
The line of the ball (LOB) is the extended path along which the ball has travelled or is travelling... The LOB is the reference for deciding precedence as between players.
