Assist

In baseball, an assist (denoted by A) is a defensive statistic, baseball being one of the few sports in which the defensive team controls the ball. An assist is credited to every defensive player who fields or touches the ball (after it has been hit by the batter) prior to the recording of a putout, even if the contact was unintentional. For example, if a ball strikes a player's leg and bounces off him to another fielder, who tags the baserunner, the first player is credited with an assist. A fielder can receive a maximum of one assist per out recorded. An assist is also credited if a putout would have occurred, had another fielder not committed an error. For example, a shortstop might field a ground ball cleanly, but the first baseman might drop his throw. In this case, an error would be charged to the first baseman, and the shortstop would be credited with an assist.

If a pitcher records a strikeout where the third strike is caught by the catcher, the pitcher is not credited with an assist. However, if the batter becomes a baserunner on a dropped third strike and the pitcher is involved in recording a putout by fielding the ball and either tagging the runner out or throwing to first base for the out, the pitcher is credited with an assist just as any other fielder would be.

Assists are an important statistic for outfielders, as a play often occurs when a baserunner on the opposing team attempts to advance on the base paths when the ball is hit to the outfield. It is the outfielder's job to field the ball and make an accurate throw to another fielder who is covering the base before the runner reaches it. The fielder then attempts to tag the runner out. This is especially important if the runner was trying to reach home plate, as the assist and tag prevent the baserunner from scoring a run. Assists are much rarer for outfielders than infielders (with the exception of first basemen) because the play is harder to make, and also because outfielder assist situations occur less often than the traditional ground-ball assist for a shortstop, second baseman, or third baseman. However, as a result, outfield assists are worth far more than infield assists, and tell more about an outfielder's throwing arm than infielder assists do.

In recent years, some sabermetricians have begun referring to assists by outfielders as baserunner kills. Some sabermetricians are also using baserunner holds as a statistic to measure outfield arms. A baserunner hold occurs when the baserunner does not attempt to advance an extra base on an outfielder out of concern of being thrown out by a strong, accurate throw. This can be combined with baserunner kills for better accuracy, as runners often do not try for an extra base when an outfielder with an excellent arm is playing.

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.
