Baseball Sacrifice Fly

In baseball, a sacrifice fly is a batted ball that satisfies four criteria:

There are fewer than two outs when the ball is hit.
The ball is hit to the outfield (fair or foul), or to infield foul territory.
The batter is put out because an outfielder (or an infielder running in the outfield, or foul territory) catches the ball on the fly (alternatively if the batter would have been out if not for an error or if the outfielder drops the ball and another runner is put out).
A runner who is already on base scores on the play.

It is called a "sacrifice" fly because the batter presumably intends to cause a teammate to score a run, while sacrificing his own ability to do so. Sacrifice flies are traditionally recorded in box scores with the designation "SF".

Rules

As addressed within Rule 10.08(d) of the Official Baseball Rules, a sacrifice fly is not counted as a turn at bat for the batter, though the batter is credited with a run batted in.

The purpose of not counting a sacrifice fly as an at-bat is to avoid penalizing hitters for a successful action. The sacrifice fly is one of two instances in baseball where a batter is not charged with a time at bat after putting a ball in play; the other is the sacrifice hit (also known as a sacrifice bunt). But, while a sacrifice fly doesn't affect a player's batting average, it counts as a plate appearance, thus lowering his on-base percentage, and a player on a hitting streak will have the hit streak end if he has no official at-bats but has a sacrifice fly. The reason for this is that the sacrifice fly, unlike the sacrifice bunt, is not considered a tactical maneuver (players don't try to hit a fly ball to advance a runner). Unlike a sacrifice bunt, which may be scored if a runner advances from any base to any base, a sacrifice fly is only credited if a runner scores on the play. Therefore, when a runner on first or second base tags on a fly ball and advances no further than third base, no sacrifice is given and the batter is charged with an at-bat. Note that, although rarely occurring, if a runner tags and advances from second base (or, theoretically, from first base) all the way to home and scores (without an intervening error) the batter is credited with a sacrifice fly.

The sacrifice fly is credited even if another runner is put out on appeal for failing to tag up, so long as a run scores prior to the third out. In the case of a fly ball dropped for an error, the sacrifice fly is only credited if the official scorer believes the run would have scored had the ball been caught.

On any fly ball, a runner can attempt to advance bases right as a fielder touches the ball. If the fielder bobbles the ball, the runner may still tag up, even before the fielder has full control of the ball (before the fielder is credited with a putout). The rule works this way because a smart fielder can theoretically purposely bobble the ball and run with it at the same time towards the infield and only completely catch it when he is within a good throwing distance to home plate. As addressed in the Official Baseball Rules, this was put into the baseball rulebook so it prevented these fielders from intentionally bobbling the ball.

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.
