  1. How to Throw A Curveball By: Kevin Lubak

  2. What Is A Curveball? • “Any of several pitches that veer to the left when thrown with the right hand and to the right when thrown with the left hand” (thefreedictionary.com) • “A curveball creates a physical effect and a perceptual puzzle”(illisuionsoftheyear.com).

  3. Brief History • William Arthur “Candy” Cummings  • “One summer day in 1864 he was playfully tossing clamshells over the ocean turf near his new home in Brooklyn. To his astonishment, the shells took on a sharp curve and returned to almost where he stood” (Wordpress.com) • “Three years later, Cummings would astonish the baseball world with his perfected curve ball. Its formal introduction came in spring of 1867” (Wordpress.com)

  4. The Variations of the curveball • The 12-6 curve • The 10-4 curve

  5. The 12-6 Curveball • The12-6 curveball is a pitch that curve in a way that works like a, clock moving in a 12 to 6 motion

  7. The 10-4 curveball • The 10-4 curveball is the more known curveball and works at a ¾ angle • Known as the “regular” curveball

  8. The 10-4 curveball

  9. The Effect Of The Curveball • “As the curve can be thrown in many ways, perception plays a big role in the curveball” (The Physics Behind Baseball) • “The secret to understanding a curveball is the speed of the air moving past the ball's surface. As the ball spins, its top surface moves in the same direction in which the air moves. At the bottom of the ball, the ball's surface and the air move in opposite directions” (exploratorium.edu)

  10. The Effect Of The Curveball •  “Dr. James Andrews, the world's foremost athlete surgeon, and his team at American Sports Medicine Institute have recently finished extensive studies they say prove, conclusively, Throwing a curve early can lead you down a dangerous road.” (Espn.go.com) • “With more competitive baseball being played, and thus more in-game, pitches being thrown, it's easy for pitch counts to add up, especially for dominant hurlers who will throw until they're told to stop.” (Espn.go.com)
