Baseball is the national sport of the United States. No one knows quite how it began. It is believed that it may have come from a similar English game called rounders. In 1845 Alexander Cartwright set up the Knickerbocker Baseball Club of New York. The rules as he laid them out established a game of nine innings, with teams of nine players each. The baseball diamond would have four bases 90 feet (27.4 m) apart.

When the pitcher throws a ball, he knows that eventually it is going to hit the ground. In order for the ball to go further, he is going to have to keep it in the air longer, before gravity forces it to earth. The way to keep it in the air longer, is to increase the angle of his throw. As soon as the ball leaves the pitchers hand, gravity begins pulling it downward. Even the fastest pitcher's smoke ball may drop as much as 2 feet (60 cm) by the time it reaches the catcher. That is why there is such a thing as a pitchers mound. The pitchers mound is 10 inches (25 cm) above the level of home plate, with a degree of slope from a point 6 inches (15 cm) in front of the pitchers mound to a point 6 feet (2 m) toward home plate. Even with the mound, the pitcher must always aim a little higher than the point where he wants the ball to go. The pitcher knows that the ball will reach a point where its upward velocity will be zero and the ball will start to drop.

The speed of a baseball is measured using a "Radar Gun". Today, in the late 1990s pitchers can throw over 100 miles per hour (160 km/h or 45 m/s). Matt Anderson, has thrown the fastest pitched baseball which measured 103 miles per hour (166 km/h or 46.0 m/s). This time was measured in the past 1999 baseball season.

Pitching is a very important technique in the game of baseball. Without a pitcher, it would be impossible for a baseball game to take place. Winning is the single most important job in the game because you can hit all the home runs you want, but if you don't have a good pitcher then you will give up as many runs as you score. The winning or losing of a game, is always decided by pitching, one way or another!
