Pitchers
In baseball, the pitcher is the player who throws (" pitches") the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter, who attempts to either make contact with the pitched ball or draw a walk. In the numbering system used to record defensive plays, the pitcher is assigned the number 1. The pitcher is often considered the most important player on the defensive side of the game, and as such is situated at the right end of the defensive spectrum. There are many different types of pitchers, such as the starting pitcher, relief pitcher, middle reliever, lefty specialist, setup man, and the closer. Traditionally, the pitcher also bats. Starting in 1973 with the American League and spreading to further leagues throughout the 1980s and 1990s, the hitting duties of the pitcher have generally been given over to the position of designated hitter, a cause of some controversy. The National League adopted the designated hitter in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (ball)
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitcher's Mound
A baseball field, also called a ball field or baseball diamond, is the field upon which the game of baseball is played. The term can also be used as a metonym for a baseball park. The term sandlot is sometimes used, although this usually refers to less organized venues for activities like sandlot ball. Specifications :''Unless otherwise noted, the specifications discussed in this section refer to those described within the Baseball Rules, under which Major League Baseball is played.'' The starting point for much of the action on the field is home plate (officially "home base"), a five-sided slab of white rubber. One side is long, the two adjacent sides are . The remaining two sides are approximately and set at a right angle. The plate is set into the ground so that its surface is level with the field. The corner of home plate where the two 11-inch sides meet at a right angle is at one corner of a square. The dimensional specifications are technically inconsistent because ...

Catcher
Catcher is a position in baseball and softball. When a batter takes their turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher. In addition to this primary duty, the catcher is also called upon to master many other skills in order to field the position well. The role of the catcher is similar to that of the wicket-keeper in cricket. Positioned behind home plate and facing toward the outfield, the catcher can see the whole field, and is therefore in the best position to direct and lead the other players in a defensive play. The catcher typically calls for pitches using PitchCom, or hand signals. The calls are based on the pitcher's mechanics and strengths, as well as the batter's tendencies and weaknesses. Essentially, the catcher controls what happens during the game when the ball is not "in play". Foul tips, bouncing balls in the dirt, and contact with runners during plays at the plate are all events ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pitching Position
In baseball, there are two legal pitch (baseball), pitching positions: the windup, and the set. Colloquially, the set is often referred to as "the stretch", although this term actually only refers to one part of the pitching motion when pitching from the set. Definitions Windup A pitcher is in the windup when, with the ball, the pitcher stands on or directly in front of the Baseball field#Pitcher's mound, pitching rubber, located at the top of the Pitchers mound, mound, with their feet pointing toward home plate. Prior to throwing a Pitch (baseball), pitch, the pitcher has the option of taking one step back toward second base or to either side, using their free leg (left leg for a right-handed pitcher). During the delivery of the pitch, the pitcher must take one step forward, in the direction of home plate. Alternatively, the pitcher may step off the rubber with their pivot foot (the right foot, for right-handed pitchers) or step toward and throw or feign a throw to a base, subject ...

Starting Pitcher
In baseball (hardball or softball), a starting pitcher or starter is the first pitcher in the game for each team. A pitcher is credited with a game started if they throw the first pitch to the opponent's first batter of a game. Starting pitchers are expected to pitch for a significant portion of the game, although their ability to do this depends on many factors, including effectiveness, stamina, health, and strategy. A starting pitcher in professional baseball usually rests three, four, or five days after pitching a game before pitching in another. Therefore, most professional baseball teams have four, five or six starting pitchers on their rosters. These pitchers, and the sequence in which they pitch, is known as the ''rotation''. A team's best starter is known as the ace, and is almost always the first man to pitch in the rotation. In modern baseball, a five-man rotation is most common. In contrast, a pitcher who enters the game after the first pitch of the game is a r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Pitcher
Power pitcher is a term in baseball for a pitcher who relies on pitch velocity at the expense of accuracy. Power pitchers usually record a high number of strikeouts, and statistics such as strikeouts per 9 innings pitched are common measures of power. An average pitcher strikes out about 5 batters per nine innings while a power pitcher will often strike out one or more every inning. The prototypical power pitcher is Hall of Fame member Nolan Ryan, who struck out a Major League Baseball record 5,714 batters in 5,386 innings. Ryan recorded seven no-hitters, appeared in eight Major League Baseball All-Star Games but also holds the record for most walks issued (2,795). Other prominent power pitchers include Hall of Famers Walter Johnson, Sandy Koufax, Pedro MartÃnez, Randy Johnson, and Bob Feller. Feller himself famously led his league in strikeouts and walks several times. The traditional school of thought on power pitching was known as "throw till you blow".Shaw, Bud. (Ma ...

Closing Pitcher
In baseball, a closing pitcher, more frequently referred to as a closer (abbreviated CL), is a relief pitcher who specializes in getting the final outs in a close game when his team is leading. The role is often assigned to a team's best reliever. Before the 1990s, pitchers in similar roles were referred to as a fireman and stopper. A small number of closers have won the Cy Young Award. Nine closers have been inducted into the Baseball Hall of Fame: Dennis Eckersley, Rollie Fingers, Goose Gossage, Trevor Hoffman, Mariano Rivera, Lee Smith, Bruce Sutter, Billy Wagner, and Hoyt Wilhelm. Usage A closer is generally a team's best reliever and designated to pitch the last few outs of games when his team is leading by a margin of three runs or fewer. Rarely does a closer enter with his team losing or in a tie game, however in the playoffs they are often brought on if it is a close game. A closer's effectiveness has traditionally been measured by the save, an official Majo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike Zone
In baseball, the strike zone is the area of space through which a pitch must pass in order to be called a strike even if the batter does not swing. The strike zone is defined as the volume of space above home plate and between the batter's knees and the midpoint of his torso. Whether a pitch passes through the zone is decided by an umpire, who is generally positioned behind the catcher. Strikes are desirable for the pitcher and the fielding team, as three strikes result in a strikeout of that batter. A pitch that misses the strike zone is called a ball if the batter does not swing at it. Balls are desirable for the batter and the batting team, as four balls allow the batter to take a "walk" to first base as a base on balls. Definition The strike zone is a volume of space, a vertical right pentagonal prism. Its sides are vertical planes extending up from the edges of home plate. The official rules of Major League Baseball define the top of the strike zone as the midpoi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base On Balls
A base on balls (BB), better known as a walk, occurs in baseball when a batter receives four pitches during a plate appearance that the umpire calls '' balls'', and is in turn awarded first base without the possibility of being called out. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08(a). Despite being known as a "walk", it is considered a faux pas for a professional player to actually walk to first base; the batter-runner and any advancing runners normally jog on such a play. The term "base on balls" distinguishes a walk from the other manners in which a batter can be awarded first base without liability to be put out (e.g., hit by pitch (HBP), catcher's interference). Though a base on balls, catcher's interference, or a batter hit by a pitched ball all result in the batter (and possibly runners on base) being awarded a base, the term "walk" usually refers only to a base on balls, and not the other methods of r ...
