They perform many duties before the game as well, such as checking players' equipment, the lines on the field, and the condition and number of baseballs available for play. While the manager is responsible for producing two copies of their lineup card, the umpire ensures that both copies are identical. For reference, each team gets a copy of the other team's lineup card. At the start of each game, the umpire checks equipment of players, checks the ground lines for chalk, checks regulation baseballs from home club for certification and that gloss is removed, checks that a dozen reserve balls are available, official rosin bag is placed on ground behind the pitcher's plate before the start, he has two alternate balls in his possession to replace if pitcher requests new one, ball becomes unfit for play, or it flies into spectator area.
The plate umpire is the final decision maker. He is responsible for all major decisions and calling pitches, strikes or balls while standing in the batter's box behind the batter and catcher. Only the team captains can make an appeal to the plate umpire without the risk of being ejected from the game.
The 1st base umpire and 3rd base umpire are responsible for calling foul balls as well as determining if a base runner is safe on-base. They will relay their call to the plate umpire. To start the game, the umpire yells, Play! He also calls Play to start the game again after a dead ball , once the pitcher, catcher, and batter are ready.
To signal that the pitch was a strike, the home plate umpire makes a fist with his right hand and makes a single, quick pounding motion. Penalties include: restricting the coach to the dugout; ejecting an offending player or coach; declaring …. This responsibility should never be taken lightly. Major League Baseball recognizes that every situation is unique and that umpire discretion is essential to proper rule enforcement. While there are unique and extraordinary circumstances, players and Clubs look to the MLB umpiring staff for uniformity in applying consistent standards for ejection.
The following general principles should be considered when deciding whether to eject a player, coach, manager, or other person from a game: Use of profanity specifically directed at an umpire or vulgar personal insults of an umpire are grounds for ejection. Physical contact with an umpire is a ground for ejection. Refusal to stop arguing, and further delaying the game after the umpire has provided a player or manager adequate opportunity to make a point, is a ground for ejection.
The umpire should warn the player or manager that he has been heard and that he should return his position or be ejected. If a player, coach, or manager leaves his position to argue balls and strikes including half swings , he should be warned to immediately return or he will be automatically ejected.
If a Replay Review is initiated, no uniformed personnel from either Club shall be permitted to further argue the contested calls or the decision of the Replay Official.
On-field personnel who violate this provision shall be ejected. In circumstances in which Replay Review is not available e. Use of histrionic gestures e. To reach a new fan base, MLB embraced visualization technologies to appeal to younger and more technologically savvy fans. MLB currently uses the Statcast system, which uses a combination of Doppler radar and optical tracking to follow the movements of the ball and player on the field.
It provides an array of important data that can improve game play, including the angle and velocity of the ball coming off the bat when a player puts a ball in play. Yet as consequential as these technologies are to the viewing and playing experience of the game, they only document the actions on the field.
This is a critically important distinction because these systems do not intervene in, augment or change the way baseball is played. As MLB works its way into the modern technological age, it is at the precipice of making an all-important leap into using technology to call balls and strikes.
The case for using technology is to remove human fallibility from the equation. In summer , the Atlantic League of Professional Baseball, an independent league, experimented with the Trackman system. At the time, Trackman was the newest automated ball-strike technology available.
Repositioning the home plate umpire to provide enhanced perceptual cues and more accurate ball-strike judgments.
Journal of Sport Behavior, 22, 28— The advantage of that particular position are two-fold: one, additional height and distance cues, and two, the advantage of being able to see pitches pass in front of the batter.
Umpires ought to be aware of this problem and should position themselves as advantageously as possible in order to increase the likelihood of making more accurate calls. One can say that they view pitches from nearly the same vantage point. Balls, strikes, and norms: Rule violations and normative rules among baseball umpires. Journal of Sport and Exercise Psychology, 10, 75— Umpires admitted that they called the upper boundary of the strike zone significantly lower than the official rule specified.
This is thought to be to the advantage of the batter, but still an error according to the rules. International Journal of Sport Behavior, 12, — Another investigation showed that umpires can be biased in their calls depending on the sequence of balls and strikes. Expert perception and decision making in baseball. International Journal of Sport Psychology, 28, 35— For proper discrimination of balls and strikes, perceptual experience is important. Several studies in fast ball sports showed that experts have superior anticipation skills when compared to less skilled counterparts and novices.
Pick-up essential kinematics underpins expert perception of movement patterns. Journal of Motor Behavior, 39, — Ventral and dorsal contributions in visual anticipation in fast ball sports. International Journal of Sport Psychology, 39, — One can therefore conclude that professional players and umpires share perceptual experience gained through watching many pitches in their careers.
The fact that they have two different tasks to execute makes the whole situation even more interesting. The difference in those tasks could have an influence on the decision-making process of umpires and players and therefore their abilities to discern balls from strikes. Two previous scientific investigations have addressed this issue. In an investigation conducted in Canada, umpires, players, and control participants without any relevant baseball experience were compared on their ability to make ball and strike calls.
