Baseball Sinker

In baseball, a sinker or sinking fastball is a type of fastball pitch which has significant downward and horizontal movement and is known for inducing ground balls. Pitchers who use the sinker tend to rely on it heavily and do not need to change pitch speeds as much as other pitchers do because the sinking action induces weak bat contact. Other pitchers normally change pitch speeds to achieve this effect. The sinker is much more often used by right-handed pitchers than left-handed pitchers.

Throwing mechanics

One method of throwing the sinker is to simply grip the baseball along the two seams and throw it similar to a fastball. Some pitchers use a downward motion on their wrist when throwing it. The pitcher's palm turns to the right at release for a right handed pitcher. This causes a sharper sink, but also has a greater risk of a wild pitch. This wrist movement is also called pronation.

Many sinker ball pitchers today turn the inside of the ball over just before releasing the ball, combined with slightly increasing the pressure on the ball with the index finger ("press inside") which creates a tilted sidespin motion that causes horizontal movement.

Effects on the batter

The sinker drops 3 to 6 inches more than a typical two-seam fastball which causes batters to hit ground balls more often than other fastballs, mostly due to the tilted sidespin on the ball. Horizontal movement also occurs when sinkers are thrown. Sinkerball pitchers can often get called strikes and swinging strikes on the pitch, so sinkerball pitches can obtain large strikeout totals.

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.
