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.
