A curveball is a baseball pitch that is thrown with a downward motion. The pitcher pronates his wrist as the ball is thrown, causing it to spin in the air. The Magnus effect causes the ball to curve towards the batter.

The Magnus effect is a force that is created when an object spins in the air. The force is perpendicular to the direction of the object's motion. In the case of a curveball, the Magnus effect causes the ball to curve downwards.

Cutter

A cutter is a baseball pitch that is thrown with a cutting action. The pitcher holds the ball with his fingers spread out and releases it with a quick, slicing motion. The ball spins in the air and cuts through the air, giving it a sharp break.

The cutter is similar to a slider, but it is thrown with a higher velocity and has more movement. The cutter is often used by pitchers to get batters to swing and miss or to hit ground balls.

Sinker

A sinker is a baseball pitch that is thrown with a downward trajectory. The pitcher pronates his wrist slightly and releases the ball with a downward motion. The ball sinks in the air and is difficult for batters to hit.

The sinker is often used by pitchers to get batters to ground out. The sinker can also be used to induce double plays.

Sweeper

A sweeper is a baseball pitch that is thrown with a sideways motion. The pitcher throws the ball with his hand at a 90-degree angle to the ground. The ball sweeps through the air, causing it to move sideways.

The sweeper is a relatively new pitch in baseball. It is often used by pitchers to keep batters off balance and to get them to swing and miss.
