Pitching 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 Official 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 other three corners of the square, in counterclockwise o ...

Baseball Diamond Marines
Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a 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 bases, having them advance counter-clockwise around four bases to score what are called " runs". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The principal objective of the batting team is to have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Baseman Brian Dozier Trying To Turn Double Play
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tag Out
In baseball and softball, a tag out, sometimes just called a tag, is a play in which a baserunner is out because a fielder touches him with the ball or with the hand or glove holding the ball, while the ball is live and the runner is in jeopardy of being put out – usually when he is not touching a base. A baserunner is in jeopardy when any of the following are true: # he is not touching a base (excluding overrunning of first base or when advancing to an awarded base, such as on a base on balls); # he is touching a base he has been forced to vacate because the batter became a baserunner (a forced runner) # he has not tagged up on a caught fly ball; # he failed to touch a base when he last passed it, or failed to touch them in order; or # he is touching a base that a preceding baserunner is also touching (excludes touching a base he was forced to advance to, in which case the preceding baserunner is in jeopardy unless also forced to advance to an awarded base) A tag is th ...

Baserunner
In baseball, base running is the act of running from base to base, performed by members of the team at bat. Base running is a tactical part of the game with the goal of eventually reaching home base (home plate) to score a run. Batters strive to become base runners, and to enable existing base runners to move to a subsequent base or to score. In statistics, the number of baserunners (for example those allowed by a pitcher) is denoted by the abbreviation BR. Becoming a runner A batter becomes a base runner when one of the following happens: * He hits the baseball into fair territory and is not put out, * He hits into a fielder's choice, * The defensive team commits an error that allows him to reach base, * There is an uncaught third strike, * He receives a base on balls, * He is hit by a pitch, or * A fielder (typically, the catcher) interferes with him. The batter-runner The Official Baseball Rules uses the term batter-runner to identify the batter from the time he becomes a ...

Foul Ball
In baseball, a foul ball is a batted ball that: * Settles on foul territory between home and first base or between home and third base, or * Bounces and then goes past first or third base on or over foul territory, or * Has its first bounce occur in foul territory beyond first or third base, or * While on or over foul territory, touches the person of an umpire or player, or any object foreign to the natural ground. By interpretation, a batted ball that touches a batter while in his batter's box is foul regardless of whether it is over foul territory. The entirety of the batted ball must be on or over foul territory in order to be adjudged foul in the above situations; otherwise it is a fair ball that forces the batter to attempt to reach first base. A foul fly shall be judged according to the relative position of the ball and the foul line, including the foul pole, and not as to whether the fielder is on foul or fair territory at the time he touches the ball. If the foul ball g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passed Ball
In baseball, a catcher is charged with a passed ball when he fails to hold or control a legally pitched ball that, with ordinary effort, should have been maintained under his control, and, as a result of this loss of control, the batter or a runner on base advances. A runner who advances due to a passed ball is not credited with a stolen base unless he breaks for the base before the pitcher begins his delivery. History A passed ball may be scored when a base runner reaches the next base on a bobble or missed catch by the catcher, or when the batter–runner reaches first base on an uncaught strike three (''see also'' Strikeout). A closely related statistic is the wild pitch. As with many baseball statistics, whether a pitch that gets away from a catcher is a passed ball or wild pitch is at the discretion of the official scorer. Typically, pitches that are deemed to be ordinarily catchable by the catcher, but are not, are ruled passed balls; pitches that get by the catcher that ...

Wild Pitch
In baseball, a wild pitch (WP) is charged against a pitcher when his pitch is too high, too short, or too wide of home plate for the catcher to control with ordinary effort, thereby allowing a baserunner, or the batter (on an uncaught third strike), to advance. A wild pitch usually passes the catcher behind home plate, often allowing runners on base an easy chance to advance while the catcher chases the ball down. Sometimes the catcher may block a pitch, and the ball may be nearby, but the catcher has trouble finding the ball, allowing runners to advance. A closely related statistic is the passed ball. As with many baseball statistics, whether a pitch that gets away from a catcher is counted as a wild pitch or a passed ball is at the discretion of the official scorer. The benefit of the doubt is usually given to the catcher if there is uncertainty; therefore, most of these situations are scored as wild pitches. If the pitch was so low as to touch the ground, or so high that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backstop (baseball)
B backdoor breaking ball :A breaking pitch, usually a slider, curveball, or cut fastball that, due to its lateral motion, passes through a small part of the strike zone on the outside edge of the plate after seeming as if it would miss the plate entirely. It may not cross the front of the plate but only the back and thus have come in through the "back door". A slider is the most common version, because a slider has more lateral motion than other breaking pitches (it curves down and 'slides' across the zone). backstop :*The fence behind homeplate, designed to protect spectators from wild pitches or foul balls. :*Catcher, sometimes "backstopper". back-to-back :Consecutive. When two consecutive batters hit home runs, they are said to hit back-to-back homers. Or a pitcher may issue back-to-back walks, and so forth. bad-ball hitter :A batter who excels at hitting pitches that are outside the strike zone. Notable bad ball hitters include Yogi Berra and Vladimir Guerrero. bad hop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentagon
In geometry, a pentagon (from the Greek πέντε ''pente'' meaning ''five'' and γωνία ''gonia'' meaning ''angle'') is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting ''regular pentagon'' (or ''star pentagon'') is called a pentagram. Regular pentagons A '' regular pentagon'' has Schläfli symbol and interior angles of 108°. A '' regular pentagon'' has five lines of reflectional symmetry, and rotational symmetry of order 5 (through 72°, 144°, 216° and 288°). The diagonals of a convex regular pentagon are in the golden ratio to its sides. Given its side length t, its height H (distance from one side to the opposite vertex), width W (distance between two farthest separated points, which equals the diagonal length D) and circumradius R are given by: :\begin H &= \frac~t \approx 1.539~t, \\ W= D &= \frac~t\approx 1.618~t, \\ W &= \sqr ...

Sacrifice Fly
In baseball, a sacrifice fly (sometimes abbreviated to sac fly) is defined by Rule 9.08(d): "Score a sacrifice fly when, before two are out, the batter hits a ball in flight handled by an outfielder or an infielder running in the outfield in fair or foul territory that # is caught, and a run scores after the catch, or # is dropped, and a runner scores, if in the scorer's judgment the runner could have scored after the catch had the fly ball been caught." It is called a "sacrifice" fly because the batter allows a teammate to score a run, while sacrificing his own ability to do so. Sacrifice flies are traditionally recorded in box scores with the designation "SF". Rules As addressed within Rule 9.02(a)(1) of the Official Baseball Rules a sacrifice fly is not counted as a time at bat for the batter, though the batter is credited with a run batted in. The same is true with a bases-loaded walk. The purpose of not counting a sacrifice fly as an at-bat is to avoid penalizing hitter ...
