Curveball
In baseball and softball, the curveball is a type of pitch thrown with a characteristic grip and hand movement that imparts forward spin to the ball, causing it to dive as it approaches the plate. Varieties of curveball include the 12–6 curveball, power curveball, and the knuckle curve. Its close relatives are the slider and the slurve. The "curve" of the ball varies from pitcher to pitcher. The expression "to throw a curveball" essentially translates to introducing a significant deviation to a preceding concept. Grip and action The curveball is typically gripped in a manner similar to holding a cup or glass. The pitcher positions the middle finger along and parallel to one of the ball’s long seams, while the thumb is placed on the seam opposite, forming a "C shape" when viewed from above, with the horseshoe-shaped seam facing inward toward the palm. The index finger is aligned alongside the middle finger, while the remaining two fingers are folded toward the palm, with ...

12–6 Curveball
The 12–6 curveball is one of the types of Pitch (baseball), pitches thrown in baseball. It is categorized as a breaking ball because of its downward break. The 12–6 curveball, unlike the normal curveball (also referred to as the "11 to 5 curve" or a "2 to 8 curve" for its motion), breaks in a downward motion in a straight line. This explains the name "12–6", because the break of the pitch refers to the ball breaking from the 12 o'clock position to 6 o'clock on a clock face. While the 11–5 and 2–8 variations are very effective pitches, they are less effective than a true 12–6, because the ball will break into the heart of the bat more readily. The pitch is used throughout Major League Baseball. It has several nicknames, including the "yellow hammer" and "drop curveball". Movement The 12 to 6 curveball is the toughest type of curveball to hit, because it moves vertically, and has no horizontal break. The difference of the speed from a fastball and the break make the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knuckle Curve
In Major League history, the term knuckle curve or knuckle curveball has been used to describe three different pitches. All are unrelated to the similar sounding knuckleball. The first, more modern and commonly used pitch called the knuckle curve is really a standard curveball, thrown with one or more of the index or middle fingers bent. According to practitioners, this gives them a better grip on the ball and allows for tighter spin and greater movement. In all other respects, this knuckle curve is identical to the standard curveball. This version of the knuckle curve was used by Major League pitchers Phil Hughes and Brad Peacock in the 2010s. Mike Mussina was well known for his incorporation of the pitch into his repertoire. Justin Verlander formerly threw a knuckle curve but was forced to abandon the pitch due to problems with blisters. This knuckle curve is usually called the spike curve by MLB players and coaches because the pitch is nothing like a knuckleball. The secon ...

Softball
Softball is a Variations of baseball, variation of baseball, the difference being that it is played with a larger ball, on a smaller field, and with only underhand pitches (where the ball is released while the hand is primarily below the ball) permitted. Softball is played competitively at club levels, the college level, and the #Professional leagues, professional level. The game was created in 1887 in Chicago by George Hancock (softball), George Hancock. There are two rule sets for softball generally: ''slow-pitch softball'' and ''fastpitch softball, fastpitch''. Slow-pitch softball is commonly played recreationally, while women's fastpitch softball was a Summer Olympic Games#List of Olympic sports, Summer Olympic sport and can be Women Professional Fastpitch, played professionally. Softball was not included in the 2024 Summer Olympics but will return for the 2028 Summer Olympics.

Magnus Effect
The Magnus effect is a phenomenon that occurs when a spin (geometry), spinning Object (physics), object is moving through a fluid. A lift (force), lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus force is dependent on the speed and direction of the rotation of the object. The Magnus effect is named after Heinrich Gustav Magnus, the German physicist who investigated it. The force on a rotating cylinder is an example of Kutta–Joukowski theorem, Kutta–Joukowski lift, named after Martin Kutta and Nikolay Zhukovsky (scientist), Nikolay Zhukovsky (or Joukowski), mathematicians who contributed to the knowledge of how lift is generated in a fluid flow. Description The most readily observable case of the Magnus effect is when a spinning sphere (or cylinder) curves away from the arc it would follow if it were not spinning. It is often used by football (soccer) and volleybal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knuckleball
A knuckleball or knuckler is a baseball pitch (baseball), pitch thrown to minimize the spin of the ball in flight, causing an erratic, unpredictable motion. The air flow over a seam of the ball causes the ball to change from Laminar flow, laminar to Turbulence, turbulent flow. This change adds a deflecting force to the baseball, making it difficult for batter (baseball), batters to hit but also difficult for pitchers to control and catchers to catch; umpires are challenged as well, as the ball's irregular motion through the air makes it harder to call strike zone, balls and strikes.Hoffman, Benjamin"Not So Easy on the Eyes"''New York Times'' (June 23, 2012) A pitcher who throws knuckleballs is known as a List of knuckleball pitchers, knuckleballer. Origins The origins of the knuckleball are unclear.

Slider (baseball)
In baseball, a slider is a type of breaking ball, a pitch that moves or "breaks" as it approaches the batter. Due to the grip and wrist motion, the slider typically exhibits more lateral movement when compared to other breaking balls, such as the curveball. The slider is generally among the fastest breaking balls, commonly ranging . A variation of the slider, known as the sweeper, is characterized as being slightly slower, but having more lateral movement. Pitches that exhibit qualities similar to that of both a slider and a curveball are referred to as a slurve. Grip and action The grip for a slider is characterized as being similar to that of a fastball. Like all pitches, the grip can take many different forms, with slight variations between pitchers suiting their individual preferences. A common feature in most slider grips is the index and middle finger being in close proximity to each other. The associated wrist motion often contributes a large amount to the pitch's move ...

Baseball
Baseball is a bat-and-ball games, bat-and-ball sport played between two team sport, teams of nine players each, taking turns batting (baseball), batting and Fielding (baseball), fielding. The game occurs over the course of several Pitch (baseball), plays, with each play beginning when a player on the fielding team (baseball), fielding team, called the pitcher, throws a Baseball (ball), ball that a player on the batting team (baseball), batting team, called the Batter (baseball), batter, tries to hit with a baseball bat, bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the Base (baseball), bases, having them advance counter-clockwise around four bases to score what are called "Run (baseball), runs". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming Base running, runners, and to prevent runners base running ...

Pitch (baseball)
In baseball, the pitch is the act of throwing the baseball toward home plate to start a play. The term comes from the Knickerbocker Rules. Originally, the ball had to be thrown underhand, much like "pitching in horseshoes". Overhand pitching was not allowed in baseball until 1884. The biomechanics of pitching have been studied extensively. The phases of pitching include the windup, early cocking, late cocking, early acceleration, late acceleration, deceleration, and follow-through. Pitchers throw a variety of pitches, each of which has a slightly different velocity, trajectory, movement, hand position, wrist position and/or arm angle. These variations are introduced to confuse the batter and ultimately aid the defensive team in getting the batter or baserunners out. To obtain variety, and therefore enhance defensive baseball strategy, the pitcher manipulates the grip on the ball at the point of release. Variations in the grip cause the seams to catch the air differently, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baseball (object)
A baseball is the ball used in the sport of baseball. It consists of a rubber or cork center wrapped in yarn and covered with white natural horsehide or cowhide, or a synthetic composite leather. A regulation baseball is in circumference i.e. in diameter, with a weight of . The leather cover is commonly formed from two saddle-shaped pieces stitched together, typically with red-dyed thread. There are 108 stitches on a regulation baseball. That stitching plays a significant role in the trajectory of a thrown baseball due to the drag caused by the interaction between the stitching and the air. Controlling the orientation of the stitches and the speed of the ball's rotation allows a pitcher to affect the behavior of the pitched ball in specific ways. Commonly employed pitches include the curveball, the slider, the two-seam fastball, the four-seam fastball, the sinker, the cutter and the changeup. History In the early, mid-1800s days of baseball, there was a great variety in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tommy John Surgery
Ulnar collateral ligament reconstruction, sometimes referred to as Tommy John surgery is a surgical graft procedure where the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere in the patient's body, or with one from a deceased donor. The procedure is common among collegiate and professional athletes in several sports, particularly in baseball. The surgery is performed to restore optimal function for repetitive elbow movements or specifically throwing ability, often extending the careers of professional athletes. In many athletes, the surgery is done more than once during their careers. The procedure was devised in 1974 by orthopedic surgeon Frank Jobe, a Los Angeles Dodgers team physician who served as a special advisor to the team until his death in 2014. It is named after the first baseball player to undergo the surgery, major league pitcher Tommy John, who played in Major League Baseball (MLB) for 26 seasons. The initial operati ...
