Baseball is a bat and ball sport played between two teams of nine players each. In baseball, a pitch is the act of throwing a baseball towards home plate to start a play. Pitchers generally throw a variety of pitches, each of which has a slightly different velocity, trajectory, movement, hand position, wrist position and arm angle. Baseball is popular in certain countries like North America, Central America, parts of South America, Caribbean, and parts of East Asia and Southeast Asia. There are four basic tools of baseball - bat, ball, mitt and field. the different pitching grips are four seam fastball, two seam fastball, three finger changeup, circle changeup, palm ball, beginners curveball, straight curveball, knuckle curveball, slider and split finger fastball. The four seam fastball is held with a basic grip and thrown naturally. It is the easiest pitch to control because of its end-over-end spin. So use its speed and its pinpoint location to freeze hitters.

Some pitchers grip it across the narrow part of the seams (called a two seam football), which produces more of a sinking fastball. A split finger fastball is also called as splitter. A split finger fastball is named after the technique of putting the index and middle finger on different sides of the ball, or "splitting" them. Credit for the invention of the curveball is generally given to William Arthur "candy" Cummings. Cummings claimed that he invented the curveball after studying the movement that sea shells made when thrown. To throw a curveball, grip the ball by placing your middle finger on the inside half of the seam and apply pressure to the ball. A knuckleball is a type of pitch thrown by a pitcher where the ball does not rotate as it moves towards home plate.

Knuckleballs are difficult to throw, catch and hit. To throw a knuckleball, the pitcher will grip the seams with the index finger and forefinger with a claw-like grip, making sure he digs his nails into the seams. Knuckleball does not emphasize velocity. Rather, the emphasis is on lack of rotation. A knuckle baller will always find a place on a professional roaster. The key to an effective changeup is deception. A change up might look like a fastball, but come in slower and lower in the strike zone. Certain tips will throwing a circle changeup is to practice the pitch before sing it in a game. Do not try to force the pitch; the grip will slow it down. To throw the circle changeup you must exert a lot of power.
