  • If the pitcher fails to deliver the ball to the striker, the umpire will warn the pitcher and then call balls on subsequent balls not delivered to the striker.


Can happen in four instances: (1) If the pitcher does not deliver the ball after drawing back his hands. (2) If the pitcher does not deliver the ball after moving “with the apparent purpose or pretension to deliver the ball.” (3) If the pitcher puts a foot in advance of the front line when the ball is delivered. (4) If both of the pitcher’s feet are not on the ground at the time he delivers the ball.

Base on Balls

    Striker Stands “on a line drawn through the center of the home base.”
  • Line extends three feet from either side of home base.
  • If the striker does not attempt to hit good pitches, the umpire will warn the striker and then call strikes on subsequent good pitches. Foul balls do not count as strikes.
  • If the striker strikes out swinging, the catcher must catch the pitch on the fly or on the first bounce.
  • If the catcher does not catch the third strike on the fly or the first bounce, the striker must try to make first base.

Batting Order

  • The first batter of an inning is the player who follows the player who made the last out of the previous inning.
  • Example: #6 batter out on a fly ball, #7 batter leads off the next inning.
    Example: #2 batter is on first base, #4 batter is at bat. #4 batter hits a ground ball, #2 batter is forced out at second base. #3 batter leads off the next inning, as #2 batter made the third out.


  • Fielder cannot catch the ball in a hat or cap.
  • Fielder cannot obstruct base runners.
  • On foul balls, ball must go to the pitcher, then outs can be made by getting the ball to the base the runner is returning to before the runner arrives. The pitcher need not wait for the foul return in the pitcher’s position.

The Umpire

  • “Shall take care that the regulations respecting balls, bats, bases, and the pitcher’s and striker’s positions, are strictly observed.”
  • “Shall be the judge of fair and unfair play.”

And in all match games, a line connecting the home and first base and the home and third base, shall be marked by the use of chalk, or other suitable material, so as to be distinctly seen by the umpire.

Sec. 5. The pitcher’s position shall be designated by two lines four yards in length, drawn at right angles to a line from home to the second base, having its center upon that line, at two fixed iron plates, placed at points fifteen and sixteen yards distant from the home base. The pitcher must stand within the lines, and must deliver the ball as near as possible over the center of the home base, and for the striker.

Sec. 6. Should the pitcher repeatedly fail to deliver to the striker fair balls, for the apparent purpose of delaying the game, or for any other cause, the umpire, after warning him, shall call one ball, and if the pitcher persists in such action, two and three balls; when three balls shall have been called, the striker shall be entitled to the first base; and should any base be occupied at that time, each player occupying them shall be entitled to one base without being put out.

Sec. 7. The ball must be pitched, not jerked nor thrown to the bat; and whenever the pitcher draws back his hand, or moves with the apparent purpose or pretension to deliver the ball, he shall so deliver it, and he must have neither foot in advance of the front line or off the ground at the time of delivering the ball; and if he fails in either of these particulars, then it shall be declared a baulk.

Sec. 8. When baulk is made by the pitcher, every player running the bases is entitled to one base, without being put out.
Sec. 9. If the ball, from a stroke of the bat, first touches the ground, the person of a player or any other object behind the range of home and the first base, or home and the third base, it shall be termed foul, and must be so declared by the umpire, unasked. If the ball first touches the ground, either upon, or in front of the range of those bases, it shall be considered fair.

Sec. 10. A player making the home base, shall be entitled to score one run.

Sec. 17. No ace nor base can be made upon a foul ball; such a ball shall be considered dead, and not in play until it shall first have been settled in the hands of the pitcher. In such cases players running bases shall return to them, and may be put out in so returning in the same manner as the striker when running to the first base.

Sec. 18. No ace or base can be made when a fair ball has been caught without having touched the ground; such a ball shall be considered alive and in play. In such players running bases shall return to them, and may be put out in so returning, in the same manner as the striker when running to first base; but players, when balls are so caught, may run their bases immediately after the ball has been settled in the hands of the player catching it.

Players running the bases must, so far as possible, keep upon the direct line between the bases; and, must make them in the following order (word deleted): first, second, third, and home, and if returning must reverse this ord er; and should any player run three feet out of this line for the purpose of avoiding the ball in the hands of an adversary, he shall be declared out.

He shall keep a record of the game, in a book prepared for the purpose; he shall be the judge of fair and unfair play, and shall determine all disputes and differences which may occur during the game; he shall take especial care to declare all foul balls and baulks, immediately upon their occurrence, unasked, and in a distinct and audible manner. He shall, in every instance, before leaving the ground, declare the winning club, and shall record his decision in the score books of the two clubs.

Sec. 31. In all matches the umpire shall be selected by the captains of the respective sides, and shall perform all the duties enumerated in section 30, except recording the game, which shall be done by two scorers, one of whom shall be appointed by each of the contending clubs.

Sec. 32. No person engaged in a match, either as umpire, scorer, or player, shall be either directly or indirectly, interested in any bet upon the game. Neither umpire, scorer, nor player shall be changed during a match, unless with the consent of both parties (except for a violation of this law), except as provided in section 29, and then the umpire may dismiss any transgressors.

Sec. 33. The umpire in any match shall determine when play shall be suspended; and if the game can not be concluded, it shall be decided by the last even innings, provided five innings have been played, and the party having the greatest number of runs shall be declared the winner.

Sec. 34. Clubs may adopt such rules respecting balls knocked beyond or outside of the bounds of the field, as the circumstances of the ground may demand; and these rules shall govern all matches played upon the ground, provided that they are distinctly made known to every player and umpire, previous to the commencement of the game.

Sec. 38. No person who shall be in arrears to any other club, or who shall at any time receive compensation for his services as a player, shall be competent to play in any match.

Sec. 39. Should a striker stand at the bat without striking at good balls repeatedly pitched to him, for the apparent purpose of delaying the game, or of giving advantage to a player, the umpire, after warning him, shall call one strike, and if he persists in such action, two and three strikes. When three strikes are called, he shall be subject to the same rules as if he had struck at three fair balls.

Sec. 40. Every match hereafter made shall be decided by a single game, unless otherwise mutually agreed upon by the contesting clubs.
