The curveball is a breaking pitch in baseball thrown with a grip and hand movement that imparts down and/or sideways spin to the ball. In Baseball, a pitch is the act of throwing a baseball toward home plate to start a play Baseball is a Bat-and-ball Sport played between two teams of nine players each A baseball is a Ball used primarily in the sport of the same name Baseball. It is therefore considered a type of breaking ball. In Baseball, a breaking ball is a pitch that does not travel straight like a Fastball as it approaches the batter.

Theory
A fastball typically has backspin, giving it relatively stable aerodynamic characteristics in flight. For the American band of the same name see Fastball (band. For the game also known as fast-pitch softball see Softball. BackSpin is an Old School Hip Hop radio station on Sirius Satellite Radio channel 43 and DISH Network channel 6043 Flight is the process by which an object achieves sustained movement either through the Air (or movement beyond Earth's atmosphere, in the case of The spin of a curveball moves in the opposite direction. This spin causes a curveball to "break", or drop down and sweep horizontally as it approaches home plate, thus frustrating the batter. A baseball field or baseball diamond is the field upon which the game of Baseball is played In Baseball, batting is the act of facing the opposing Pitcher and trying to produce offense for one's team
When throwing a curve, the pitcher creates downspin by rolling his palm and fingers over the top of the ball while releasing it. In Baseball, the pitcher is the player who throwsthe baseball from the Pitcher's mound toward the Catcher to begin each play with the goal of The direction of the break depends on the axis of spin on the ball. There are many variations of the curveball, but most are described in terms of their movement when superimposed on a clock. A "12–6" or "overhand" curve has a more or less straight downward action as it approaches the plate, while more sweeping curveballs might be described as "1–7" or "slurves". The slurve is a pitch in which the pitcher throws a slider as if they were throwing a Curve ball. There is no specific point where a ball breaks, but the deviation from a fastball trajectory becomes progressively greater as the ball approaches the plate.
Generally the Magnus effect describes the laws of physics that make a curveball curve. The Magnus effect is the phenomenon whereby a spinning object flying in a Fluid creates a Whirlpool of fluid around itself and experiences a force perpendicular A fastball travels through the air with backspin, which creates a high-pressure zone in the air ahead of and under the baseball. The baseball's raised seams augment the ball's ability to churn the air and create high pressure zones. The effect of gravity is temporarily counteracted as the ball rides on and into energized air. Gravitation is a natural Phenomenon by which objects with Mass attract one another Thus the travel of a fastball is more or less straight, at least over the distance from the mound to home plate.
On the other hand, a curveball, thrown with topspin, creates a high-pressure zone on top of the ball, which deflects the ball downward in flight. For the fictional characters see Topspin (Transformers. In sports in particular Racquet sports ' topspin is a property of a shot where Combined with gravity, this gives the ball an exaggerated drop in flight that is difficult for the hitter to track. The curveball may have some horizontal movement as well, depending on the tilt of its axis of spin.
At the professional level, a curveball is usually about 15 miles per hour slower than a fastball. Curveball behavior is unique to each pitcher though, and varies. Some use a more looping slow curve and some use a harder, faster slurve. The speed difference between a curveball and fastball, as well as the curveball's movement, serve to deceive the batter. Ideally, a curveball will have its greatest break just as it reaches the plate and cause the batter to swing above it.
To throw a curveball correctly, proper spin must be given to the ball as it is released. Generally pitchers grip the ball deeper into their palm and fingers than they would a fastball. Pitchers usually position their index finger aside one the ball's raised seams in for more leverage in spinning the baseball. At the release point they then roll their hand over the top of the ball to throw it forward with downspin. If this movement is poorly executed the ball will have lazy spin, not break in flight, and be much easier to hit—the "hanging curve".
When thrown correctly, it could have a huge break from seven to as much as 20 inches.
A popular nickname for a curveball is the "deuce", since it is commonly the number 2 pitch in a pitcher's repertoire. [1] Catchers often use a two-finger signal when requesting the curveball. Other popular nicknames for the pitch include: "hammer", "bender", "hook", "yakker", "Public Enemy No. 1", "Lord Charles",The Spida and "Uncle Ray". [1]
Injuries
A curveball, because of the risk of injury to the pitcher’s elbow and shoulder, could be considered a more advanced pitch; geared more towards pitchers with more developed and mature arms, the curve ball can be very effective, yet very dangerous. It is suggested that the pitcher be close to 15 years old before attempting a curve ball. It is not a matter of being able to learn how to throw it, but it is a matter of the maturity of the pitcher’s arm. Important factors to consider before learning how to throw a curve: Has the child hit puberty; How developed are the child’s muscles and connective tissues, i. e. —ligaments, tendons, and bones; Is the pitcher in the middle of a growth spurt; Has the pitcher been taught the correct mechanics in order to throw a curveball? The parts of the arm that are most commonly injured by the curve ball are the ligaments in the elbow, the biceps and the forearm muscles. [2]
History
Baseball lore has it that the curveball was invented in the late 19th Century by either Candy Cummings [1] or Fred Goldsmith. William Arthur "Candy" Cummings ( October 18, 1848 &ndash May 16, 1924) was a 19th-century professional Baseball For the football coach formerly of the Rice Owls and Duke Blue Devils see Fred Goldsmith (coach or for Australian Brownlow Medalist see Fred Goldsmith An early demonstration of the "skewball" or curveball occurred at the Capitoline Grounds in Brooklyn in August of 1870 by Fred Goldsmith. In 1884, St. Nicholas, a children's magazine, featured a story entitled, "How Science Won the Game". The St Nicholas Magazine (1873-1941 was a successful American children's magazine published by Scribner's beginning in November 1873 and designed for It told of how a boy pitcher mastered the curve ball to defeat the opposing batters. In the early years of the sport, use of the curveball was thought to be dishonest and was outlawed, but officials could not do much to stop pitchers from using it. In the past, major league pitchers Bob Feller, Virgil Trucks, Herb Score, Camilo Pascual and Sandy Koufax were regarded as having outstanding curveballs. Robert William Andrew "Bob" Feller (born November 3, 1918 in Van Meter Iowa) nicknamed the "Heater from Van Meter" and Virgil Oliver Trucks (born April 26 1917) is a former Starting pitcher in Major League Baseball.

Rik Aalbert "Bert" Blyleven (born April 6, 1951 in Zeist, Netherlands) is a former Major League Baseball Pitcher Other notable pitchers who throw or threw great curveballs since 1900 are/were, Sal Maglie, Dwight Gooden, Nolan Ryan, Darryl Kile, Barry Zito, Orel Hershiser, Tom Gordon, Aaron Sele, and Ben Sheets. Salvatore Anthony Maglie ( April 26, 1917 - December 28, 1992) was a Major League Baseball player for the New York Giants Dwight Eugene Gooden (born November 16, 1964 in Tampa Florida) also known as Doc Gooden or Dr Lynn Nolan Ryan Jr (born January 31, 1947 in Refugio, Texas) is a retired American Right-handed Pitcher in Darryl Andrew Kile ( December 2 1968 – June 22 2002) born in Garden Grove California, was an American right-handed Barry William Zito (born May 13, 1978 in) is a Left handed Starting pitcher for the San Francisco Giants of Major League Baseball Orel Leonard Hershiser IV (born September 16, 1958) is a former Right-handed Pitcher in Major League Baseball.

In 1949 Ralph B. Lightfoot, an aeronautical engineer at Sikorsky Aircraft, used wind tunnel tests to prove that a curve ball actually curves and is not an optical illusion. [2] Lightfoot is in the Baseball Hall of Fame for this work.
Regardless of the evidence, some viewers over the years remained convinced that the curveball was an optical illusion. This article is about visual perception See Optical Illusion (Album for information about the Time Requiem album Baseball Hall of Fame pitcher Dizzy Dean has been quoted in a number of variations on this basic premise: "Stand behind a tree 60 feet away, and I'll whomp you with an optical illusion!"
