Sistema Peralta

Last updated

Sistema Peralta (Peralta system) is a baseball strategy where the pitching rotation in a 9-inning game is approximately divided amongst three pitchers throwing three innings each (3-3-3). Simply put, "one pitcher every three innings". This system contrasts with the more traditional strategy of having a starting pitcher, who handles the bulk of the pitching workload (typically over 5 innings), and reliever(s) who finish up the game (i.e. 5-2-2, 5-2-1-1, among various other combinations). It bears the name of entrepreneur and Tigres del Mexico founder Alejo Peralta who established and implemented its use with Tigres starting in the 1970s. [1]

Baseball Sport

Baseball is a bat-and-ball game played between two opposing teams who take turns batting and fielding. The game proceeds when a player on the fielding team, called the pitcher, throws a ball which a player on the batting team tries to hit with a bat. The objectives of the offensive team are to hit the ball into the field of play, and to run the bases—having its runners advance counter-clockwise around four bases to score what are called "runs". The objective of the defensive 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 team that scores the most runs by the end of the game is the winner.

Starting pitcher baseball or softball pitcher who throws the first pitch for their team in a game

In baseball, 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. A pitcher who enters the game after the first pitch of the game is a relief pitcher. 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.

Relief pitcher baseball or softball pitcher who relieves a previous pitcher

In baseball and softball, a relief pitcher or reliever is a pitcher who enters the game after the starting pitcher is removed due to injury, ineffectiveness, fatigue, ejection, or for other strategic reasons, such as inclement weather delays or pinch hitter substitutions. Relief pitchers are further divided informally into various roles, such as closers, setup men, middle relief pitchers, left/right-handed specialists, and long relievers. Whereas starting pitchers usually rest several days before pitching in a game again due to the number of pitches thrown, relief pitchers are expected to be more flexible and typically pitch more games but with fewer innings pitched. A team's staff of relievers is normally referred to metonymically as a team's bullpen, which refers to the area where the relievers sit during games, and where they warm-up prior to entering the game.

Background

The strategy is an adaptation from early research theories proposed by mechanical engineering professor at Princeton University and baseball statistician Earnshaw Cook. [2] For games not enforcing the designated hitter rule, Cook realized that he could start the game with a series of relievers and use a designated batter when the pitcher would normally bat. After doing so, in the following half inning where his team had to pitch, he would place the next reliever. This is done until the end of 4 whole innings where he would put in the starting pitcher and proceed as normal until the end of the game.
