What is a change up pitch?

A change-up pitch is a type of pitch in baseball, typically thrown by a pitcher, that is designed to deceive the batter by slowing down the speed of the ball as it approaches the plate. This pitch is typically thrown with the same arm motion as a fastball, but with a different grip and release point that causes the ball to travel slower and with less spin. A good change-up can be a highly effective weapon for a pitcher, as it can cause the batter to swing too early or miss altogether, resulting in a strikeout or a weakly hit ball. However, the change-up can also be risky for pitchers, as a poorly executed pitch can leave the ball hanging over the plate and lead to a hit or home run. Some common grips used for change-ups include the circle change, the Vulcan change, and the palmball.
