rules to play baseball

The part of the field closest to the bases is called the infield, and the grassy farther reaches is called the outfield.The bases are 90 feet apart on the diamond, closer in childrens leagues and softball. Other fields are variable, and the outfield fences or the amount of foul territory the amount of ground that borders the field between the long white lines that connect first base to home plate and third base to home plate varies from field to field.

Theres a pitcher in the middle of the mound who initiates the action by throwing the ball toward home plate. The catcher catches the ball if its not hit. The infielders are the first baseman, second baseman, shortstop (between second and third base) and the third baseman. There are three outfielders The left fielder, center fielder and right fielder.

One run shall be scored each time a runner legally advances to and touches first, second, third and home base before three men are put out to end the inning.
EXCEPTION A run is not scored if the runner advances to home base during a play in which the third out is made.
(1) by the batter runner before he touches first base;
(2) by any runner being forced out; or
(3) by a preceding runner who is declared out because he failed to touch one of the bases.

The pitcher shall stand facing the batter, his entire pivot foot on, or in front of and touching and not off the end of the pitchers plate, and the other foot free. From this position any natural movement associated with his delivery of the ball to the batter commits him to the pitch without interruption or alteration. He shall not raise either foot from the ground, except that in his actual delivery of the ball to the batter, he may take one step backward, and one step forward with his free foot.

Set Position shall be indicated by the pitcher when he stands facing the batter with his entire pivot foot on, or in front of, and in contact with, and not off the end of the pitchers plate, and his other foot in front of the pitchers plate, holding the ball in both hands in front of his body and coming to a complete stop. From such Set Position he may deliver the ball to the batter, throw to a base or step backward off the pitchers plate with his pivot foot. Before assuming Set Position, the pitcher may elect to make any natural preliminary motion such as that known as the stretch. But if he so elects, he shall come to Set Position before delivering the ball to the batter. After assuming Set Position, any natural motion associated with his delivery of the ball to the batter commits him to the pitch without alteration or interruption.

Each team has nine players in its batting order, and they must stick to that order throughout the game (players may substitute in for other players). A play begins with a batter waiting to hit a pitch from the pitcher. If the batter hits the ball into the field of play, the batter runs to first base and can run to as many bases as he or she deems fit without getting out.
A batter gets three strikes (a swing and a miss or a ball over the plate in whats deemed the strike zone by an umpire) or he or she is out. If there are four balls (a pitch that is not in the strike zone), the batter is automatically allowed to go to first base.
When a batter begins running, he or she is then referred to as a runner. Runners attempt to reach a base, where they are safe and can remain on the base until the next hitter comes up. The defensive players attempt to prevent this by putting the runners out using the ball; runners put out must leave the field.
A batter gets a hit when he or she reaches a base without getting out, or forcing another runner to get out (and without the defense making an error). Runs are scored when a player completes a circuit of the diamond before there are three outs in the inning.
If a players hits the ball over the outfield fence in fair territory (between the foul lines), its a home run, and the batter can circle all four bases.

There are many ways that the team on defense can get an offensive player out. Four common ways are
Strikeouts (hitter misses three pitches)
Force outs (when, after the ball is hit, the defensive player with the ball reaches a base before the runner)
Fly outs (when a player hits the ball in the air and its caught by a defensive player before the ball hits the ground)
Tag outs (when a runner is touched with the ball, or a glove with the ball in it)
