Baseball Designated Hitter

In baseball, the designated hitter rule is the common name for Major League Baseball Rule 5.11, adopted by the American League in 1973. The rule allows teams to have one player, known as the designated hitter (abbreviated DH), to bat in place of the pitcher. Since 1973, most collegiate, amateur, and professional leagues have adopted the rule or some variant. MLB's National League and Nippon Professional Baseball's Central League are the most prominent professional leagues that do not use a designated hitter.

Major League Baseball Rule

In Major League Baseball, the designated hitter is a hitter who does not play a position, but instead fills in the batting order for the pitcher. The DH may only be used for the pitcher (and not any other position player), as stated in Rule 6.10. Use of the DH is optional, but must be determined prior to the start of the game. If a team does not begin a game with a DH, the pitcher (or a pinch-hitter) must bat for the entire game.

The designated hitter may be replaced as DH only by a player who has not entered the game. If a pinch hitter bats for, or a pinch runner runs for, the DH, that pinch-hitter or pinch-runner becomes the DH.

The designated hitter can be moved to a fielding position during the game. If the DH is moved to another position, his team forfeits the role of the designated hitter, and the pitcher or another player (the latter possible only in case of a multiple substitution) would bat in the spot of the position player replaced by the former DH. If the designated hitter is moved to pitcher, any subsequent pitcher (or pinch-hitter thereof) would bat should that spot in the batting order come up again (except for a further multiple substitution). Likewise, if a pinch-hitter bats for a non-pitcher, and then remains in the game as the pitcher, the team would forfeit the use of the DH for the remainder of the game, and the player who was DH would become a position player (or exit the game).

Unlike other positions, the DH is "locked" into the batting order. No multiple substitution may be made to alter the batting rotation of the DH. In other words, a double switch involving the DH and a position player is not legal. For example, if the DH is batting fourth and the catcher is batting eighth, the manager cannot replace both players so as to have the new catcher bat fourth and the new DH bat eighth. Once a team loses its DH under any of the scenarios discussed in the previous paragraph, the double switch becomes fully available, and may well be used via necessity, should the former DH be replaced in the lineup.

Baseball

Baseball is a bat-and-ball game played between two teams of nine players each who take turns batting and fielding. The batting team attempts to score runs by hitting a ball that is thrown by the pitcher with a bat swung by the batter, then running counter-clockwise around a series of four bases: first, second, third, and home plate.

Rules and gameplay: A game is played between two teams, each comprising nine players, that take turns playing offense (batting and baserunning) and defense (pitching and fielding).

Baseball field: A baseball field, also called a ball field or a baseball diamond, is the field upon which the game of baseball is played.

Equipment: A rounded, solid wooden or hollow aluminum bat. Wooden bats are traditionally made from ash wood, though maple and bamboo is also sometimes used.

Player rosters: Roster, or squad, sizes differ between different leagues and different levels of organized play. Major League Baseball teams maintain 25-player active rosters.

Non players: In the game of baseball, the official scorer is a person appointed by the league to record the events on the field, and to send the official scoring record of the game back to the league offices.

Distinctive elements: Baseball has certain attributes that set it apart from the other popular team sports in the countries where it has a following, including American and Canadian football, basketball, ice hockey, and soccer.

Defensive Play: Baseball is unlike most other competitive sports in that the defense is given control of the ball.

Offensive Play: Batting is the act of facing the opposing pitcher and trying to produce offense for one's team. A batter or hitter is a person whose turn it is to face the pitcher.

Batting order (1-9): The batting order or batting lineup is the sequence in which the members of the offense take their turns in batting against the pitcher.

Strategy and tactics: Many of the pre-game and in-game strategic decisions in baseball revolve around a fundamental fact: in general, right-handed batters tend to be more successful against left-handed pitchers and, to an even greater degree, left-handed batters tend to be more successful against right-handed pitchers.
Baseball Positions

Baseball Positions

At the beginning of each half-inning, the nine players on the fielding team arrange themselves around the field. One of them, the pitcher, stands on the pitcher's mound.

Defensive Players

Pitcher (P): The pitcher is the player who throws 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.

Catcher (C): When a batter takes his/her turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher.

First Baseman (1B): First base, or 1B, is the first of four stations on a baseball diamond which must be touched in succession by a baserunner in order to score a run for that player's team.

Second Baseman (2B): The second baseman often possesses quick hands and feet, needs the ability to get rid of the ball quickly, and must be able to make the pivot on a double play.

Third Baseman (3B): The third baseman requires good reflexes in reacting to batted balls, as he or she is often the closest infielder (roughly 90–120 feet) to the batter.

Shortstop (SS): The position is mostly filled by defensive specialists, so shortstops are generally relatively poor batters who bat later in the batting order, with some exceptions.

Left Fielder (LF): Outfielders must cover large distances - speed, instincts, and quickness in reacting to the ball are key. They must be able to catch fly balls above their head and on the run.

Center Fielder (CF): A center fielder, abbreviated CF, is the outfielder in baseball who plays defense in center field – the baseball fielding position between left field and right field.

Right Fielder (RF): Right field is the area of the outfield to the right of a person standing at home plate and facing towards the pitcher's mound.

Offensive Players

Batter: A batter or hitter is a person whose turn it is to face the pitcher. The three main goals of batters are to become a baserunner, drive runners home, or advance runners along the bases for others to drive home.

Runner: In general, base running is a tactical part of the game with the goal of eventually reaching home to score a run.

Designated Hitter: The rule allows teams to have one player, known as the designated hitter (abbreviated DH), to bat in place of the pitcher.

Pinch Hitter: Batters can be substituted at any time while the ball is dead (not in active play); the manager may use any player who has not yet entered the game as a substitute.

Pinch Runner: The pinch runner may be faster or otherwise more skilled at base-running than the player for whom the pinch runner has been substituted.

Lead Off: A lead or lead off is the short distance that a player stands away from their current base.

Lead Off Hitter: Leadoff hitters must possess certain traits to be successful: they must reach base at a proficient on-base percentage rate and be able to steal bases.

Cleanup Hitter: Cleanup hitters often have the most power on the team and are typically the team's best power hitter; their job is to "clean up the bases", hence the name.
