Exit Velocity
In baseball statistics, exit velocity (EV) is the estimated speed at which a batted ball is travelling as it is coming off the player's bat. Batters generally aim for a higher exit velocity in order to give opposing fielders less time to react and attempt a defensive play; however, many batters are still able to accrue hits without a high exit velocity. A pitcher will attempt to limit the exit velocity on the opposing batter's contact in order to allow the fielders or themself a better chance at making an out. Exit velocity was first tracked by Major League Baseball (MLB) in 2015 with the introduction of Statcast. In MLB and many other North American baseball leagues, exit velocity is measured and presented in miles per hour. Origins For most of baseball's history, there were no commonplace methods to quantify how hard-hit a batted ball was — the only aspect of the ball's speed being tracked was how fast the pitcher threw it, measured using various evolutions of radar g ...

Humidor
A humidor is a humidity-controlled box or room used primarily for storing cigars, cigarettes, cannabis, or pipe tobacco. Either too much or too little humidity can be harmful to tobacco products; a humidor's primary function is to maintain a steady, desirable moisture level inside; secondarily it protects its contents from physical damage and deterioration from sunlight. For private use, small wooden boxes holding a few dozen or fewer cigars are common, while cigar shops may have walk-in humidors. Many humidors use hygrometers to monitor their humidity levels. Another use for a humidor is controlling the moisture level in a baseball, which can have a pronounced effect on its response when hit with a baseball bat. This phenomenon was so great that in order to put an end to much controversy, in 2002, nine years after joining the league, the Colorado Rockies started storing their game balls in a large walk-in humidor at their home stadium, thus counteracting the effects of the low ...

Imputation (statistics)
In statistics, imputation is the process of replacing missing data with substituted values. When substituting for a data point, it is known as "unit imputation"; when substituting for a component of a data point, it is known as "item imputation". There are three main problems that missing data causes: missing data can introduce a substantial amount of bias, make the handling and analysis of the data more arduous, and create reductions in efficiency. Because missing data can create problems for analyzing data, imputation is seen as a way to avoid pitfalls involved with listwise deletion of cases that have missing values. That is to say, when one or more values are missing for a case, most statistical packages default to discarding any case that has a missing value, which may introduce bias or affect the representativeness of the results. Imputation preserves all cases by replacing missing data with an estimated value based on other available information. Once all missing values h ...

Hawk-Eye
Hawk-Eye is a computer vision system used in numerous sports such as cricket, tennis, Gaelic football, badminton, hurling, rugby union, association football and volleyball, to visually track the trajectory of the ball and display a profile of its statistically most likely path as a moving image. The onscreen representation of the trajectory results is called Shot Spot. The Sony-owned Hawk-Eye system was developed in the United Kingdom by Paul Hawkins. The system was originally implemented in 2000 for television purposes in cricket. The system works via six (sometimes seven) high-performance cameras, normally positioned on the underside of the stadium roof, which track the ball from different angles. The video from the six cameras is then triangulated and combined to create a three-dimensional representation of the ball's trajectory. Hawk-Eye is not infallible, but is advertised to be accurate to within 3.6 millimetres and generally trusted as an impartial second opinion in s ...

TrackMan
The TrackMan is a radar system that uses Doppler technology to track and record 3D characteristics of a sports ball in motion. History TrackMan was created in 2003 by golfers Klaus (CEO) and Morten Eldrup-Jørgensen and radar engineer Fredrik Tuxen ( CTO). Tuxen worked with the tracking of bullets and missiles using Doppler radar. The Jorgensen brothers contacted him to see if the technology could be used to track golf balls. The team developed the TrackMan system and demonstrated it in the United States to five golf manufacturers. Mizuno, Nike, Ping, Callaway, and TaylorMade became TrackMan's first customers. TrackMan products are sold worldwide to professionals, amateurs, and businesses. The company's headquarters is in Vedbæk, Denmark. Usage Golf The TrackMan is a device that uses Doppler radar to monitor the launch of a golf ball. It is set up behind the golfer and is roughly the size of a laptop. With each swing, it measures every aspect of the club movement, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Speed Gun
A radar speed gun (also radar gun and speed trap gun) is a device used to measure the speed of moving objects. It is used in law-enforcement to measure the speed of moving vehicles and is often used in professional spectator sport, for things such as the measurement of bowling speeds in cricket, speed of pitched Baseball (ball), baseballs, and speed of tennis serves. A radar speed gun is a Doppler radar unit that may be hand-held, vehicle-mounted or static. It measures the speed of the objects at which it is pointed by detecting a change in frequency of the returned radar signal caused by the Doppler effect, whereby the frequency of the returned signal is increased in proportion to the object's speed of approach if the object is approaching, and lowered if the object is receding. Such devices are frequently used for speed limit enforcement, although more modern LIDAR speed gun instruments, which use pulsed laser light instead of radar, began to replace radar guns during the firs ...

Baseball Statistics
Baseball statistics play an important role in evaluating the progress of a player or team. Since the flow of a baseball game has natural breaks to it, and normally players act individually rather than performing in clusters, the sport lends itself to easy record-keeping and statistics. Statistics have been kept for professional baseball since the creation of the National League and American League, now part of Major League Baseball. Many statistics are also available from outside Major League Baseball, from leagues such as the National Association of Professional Base Ball Players and the Negro leagues, although the consistency of whether these records were kept, of the standards with respect to which they were calculated, and of their accuracy has varied. Development The practice of keeping records of player achievements was started in the 19th century by Henry Chadwick. Based on his experience with the sport of cricket, Chadwick devised the predecessors to modern-day statist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miles Per Hour
Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour.
