Rule 2 – Section 5 – FAIR BALL / BASE HIT
2-5-1 A fair ball is a batted ball which:
- settles on fair territory between home and third base or between home and first base; or
- contacts fair ground on or beyond an imaginary line between first and third base; or
- is on or over fair ground when bounding to the outfield past first or third base; or
- first falls on fair ground on or beyond first or third base; or
- touches first, second or third base; or
- while on or over fair territory, touches the person of an umpire or player, their clothing or equipment; or
- while over fair ground passes out of the playing field in flight. (1) A fly ball or line drive, which passes over or inside first or third base in flight and curves to foul ground beyond such base, is not a fair hit; but a hit which goes over or through the fence is a fair hit if it is over fair ground when it leaves the field.
2-5-2 A base hit (also called a safe hit or single) is one which enables the batter to advance to first base without being put out (9-3-2).
2-5-3 An extra base hit is one which enables the batter to advance to first base and then to one or more succeeding bases (9-3-3). A two-base hit (double), three-base hit (triple) or home run enables him to reach second, third or home base, respectively.
