It is the slowest breaking ball (slower than a slider). The average speed of a curveball in the majors is 77 mph. The ball will typically slow down 8-10 mph by the time it reaches the front of the plate. (Note that your home radar gun may stop reading well before the ball reaches the plate because the hitter is in the way.) Catcher's Sign

When releasing a curveball, your wrist will be hooked and your hand will pull down in front of your body. It is important that you release the ball close to your body (Short Arm). The further you release from your body, the less resistance your middle finger will have on the seam and therefore your rotation will be looser.

Invention of the curveball is credited to William "Candy" Cummings [1]. In 1863, Cummings discovered that he could cause a baseball to curve downward by rolling the ball off his second fingertip and accompanying his usual throwing motion with a hard torque of the wrist to impart topspin on the baseball.

A curveball, thrown with topspin, creates a higher pressure zone on top of the ball, which deflects the ball downward in flight. Instead of counteracting gravity, the curveball adds additional downward force, thereby gives the ball an exaggerated drop in flight. (figure 4). (Adair, 1995). Figure 4: Magnus effect of a curveball
