Baseball is a highly complex game played between 2 teams of 9 players. The winning team is the one that scores the most runs in, normally, a 9-inning game.

The baseball playing field consists of an infield (incorporating the ‘diamond’ which covers the 3 field bases and home base) and an outfield. The diamond must be 27.5 metres (90 feet) square, and under the rules the nearest boundary must be a minimum of 76 metres (250 feet) from the apex of the diamond (Home Plate).

The baseball bat can be made of various materials. Aluminium, wood and baum(composite) are the three most popular types of bat. Bats can vary in both length and weight but must have a diameter of not more than 7 centimetres (2 3/4" diameter) at its thickest point and must not exceed 107 cm (42") in length.

A baseball, thrown from a distance of 18 m (60' 6") by the pitcher, is made from white horsehide sewn over a sphere of rubber or cork, has a diameter of 22.9 - 23.5 cm (9 -9.25"), and weighs 142 - 149 grams (5 - 5.25 oz).

The shape and size of a baseball glove differs depending on the position in which the player will be playing. A first base fielder's glove is usually larger than other fielders, and the catcher's mitt has extra padding in the palm area of the glove.

A side scores a run when one player covers the 3 infield bases and safely reaches home base. ‘Home Run’ is the term used to describe a batter hitting the ball, either out of the ground and inside the foul lines or far enough to cause fieldsmen problems, and covering the 3 bases and reaching home base. A grand slam homer, which counts for 4 runs, is scored when the batter, and 3 players already safely on base, all reach home base.
