Baseball Infield Fly Rule

The infield fly rule is a rule of baseball that treats certain fly balls as though caught, before the ball is caught and even if the infielder fails to catch it or drops it on purpose. The umpire's declaration of an infield fly means that the batter is out (and all force plays are removed) regardless of whether the ball is caught. The rule exists to prevent the defense from achieving a double play or triple play by failing to catch a ball that an infielder could catch with ordinary effort. The rule is limited to apply only in situations where this result is possible.

A ball batted into the air subjects baserunners to a dilemma. If the ball is caught, they must return to their original base; if not caught, the batter becomes a runner and certain runners are forced to advance to the next base. Baserunners study the fielder and advance only far enough from the base to ensure that they can return safely. If a presumed catch becomes a non-catch, forced runners must run forward instead of back. This creates an advantage for the defense in intentionally failing to execute an easy catch, which the infield fly rule exists to remove.

The rule

Under the Official Baseball Rules used in Major League Baseball and many lower leagues, "Infield Fly" is explained in the definitions of terms: Infield Fly, and rule 5.09 (Batter is out).

The rule applies only when there are fewer than two outs, and there is a force play at third base (i.e., when there are runners at first and second base, or the bases are loaded). In these situations, if a fair fly ball is in play, and in the umpire's judgment is catchable by an infielder with ordinary effort, the umpire shall call "infield fly" (or more often, "infield fly, batter is out") and the batter will be out regardless of whether the ball is actually caught. Umpires typically raise the right arm straight up, index finger pointing up, to signal the rule is in effect.

If "infield fly" is called and the fly ball is caught, it is treated exactly as an ordinary fly ball; the batter is out, there is no force, and the runners must tag up. On the other hand, if "infield fly" is called and the ball lands fair without being caught, the batter is still out, there is still no force, but the runners are not required to tag up. In either case, the ball is live, and the runners may advance on the play, at their own peril.

An infield fly may be declared by any umpire on the field.

"Umpire's judgment"

The infield fly rule is a judgment call, as the rule states that "The judgment of the umpire must govern". The rule directs the umpire to declare an infield fly immediately on determining that the play meets the criteria described above, solely based on the umpire's discretion. Since different umpires may have different definitions of what constitutes "ordinary effort," the rule may be applied differently depending on the umpire and game conditions.

"Catchable by an infielder"

Any fair fly ball that could be caught by an infielder with ordinary effort is covered by the rule, whether or not it is in the infield, and whether or not an infielder catches it, or even attempts to catch it. For example, if an infielder retreats to the outfield in an effort to catch a fly ball, the infield fly rule may be invoked because the ball could have been caught by the infielder. Similarly, infield fly may also be called if an outfielder runs into the infield to catch a fly ball, if it could have been caught by an infielder with ordinary effort. It may be helpful to think of it as the "infielder fly rule". Specifically, the rule states an infield fly call should be determined by "whether the ball could ordinarily have been handled by an infielder, not by some arbitrary limitation such as the grass, or the base lines. The umpire must rule also that a ball is an infield fly, even if handled by an outfielder, if, in the umpire's judgment, the ball could have been as easily handled by an infielder."

"Ordinary effort"

The term "ordinary effort" considers all circumstances, including weather, lighting, positioning of the defense, and the abilities of the players involved in the play. A fly ball catchable with ordinary effort in Major League Baseball might not be in a junior high school game, due to the ability of the players involved.

Foul balls

If the fly ball is near the foul lines, the umpire is to declare "infield fly, if fair". If the ball is not caught and ends up foul (including if it lands fair and then rolls foul before passing first or third base without being touched by a fielder), the infield fly call is canceled, and the play is treated as an ordinary foul ball. In contrast, if the ball lands foul and then rolls fair before passing first or third base without being touched, the infield fly takes effect and the batter is out.

Statistics

Declarations of the infield fly rule are not included in the statistical summary of a baseball game and are not a separate category in player statistics.

A fielder who misplays an infield fly is not charged with an error because the batter is out through the infield fly rule. In fact, the fielder who should have caught an infield fly earns a putout. But a fielder who fails to touch an infield fly that then rolls foul may be charged with an error for letting the ball roll foul; the batter is not out, and the misplay prolongs the batter's time at bat.

History

The rule was first introduced in 1895 by the National League in response to infielders intentionally dropping pop-ups to get multiple outs by forcing out the runners on base, who were pinned near their bases while the ball was in the air. At that time, the rule only applied with one man out.

The current rule came into effect in 1901. It was amended in 1904 to not apply to line drives, and in 1920 to not apply to bunts.

Additional details

Second base unoccupied

The infield fly rule is not in effect if there is no runner on second base. Provided the batter runs to first base, the greatest benefit the defense could achieve by intentionally letting the fly ball drop untouched is to force out the runner at second rather than the batter, resulting in a runner on first base either way. However, if the batter is significantly slower than the runner, the defense may elect to let the ball drop untouched and achieve the force play, replacing the runner at first base with the batter.

Risks for the defense are that the uncaught ball may roll away from the fielder, and any runner on third base can try to score but has the option of remaining on his base.

If the batter gives up on the play, the defense can achieve outs at second base and first base by deliberately letting the ball drop untouched.

Intentional drop rule

A related rule called the intentional drop rule (Rule 5.09(a)(12)) applies even when second base is unoccupied, and applies even when the batted ball is a line drive or a bunt that could be caught on the fly. This rule likewise prevents a fielder from deliberately dropping a ball and thereby achieving a double or triple play. If an umpire invokes this rule, the drop is ruled a catch, the ball is dead, and no baserunner may advance. The rule is not invoked when a fielder plays a ball on a bounce that might have been caught on the fly.

Runner advancement

For the runners, an infield fly is little different from an ordinary fly ball. If an infield fly is caught, the runners must retouch their original bases ("tag up") after the catch before attempting to advance. If an infield fly is not caught, no tag up is required and the runners may advance at their own risk. The only difference is that the umpire's declaration that the batter is out removes force plays and gives runners the option of staying on the base.

The infield fly rule states that runners may advance "after the ball is touched". This rule governs the tag up if the infield fly is caught. The runner does not need to wait on base until the fielder achieves full control of the ball. There is no need to tag up at any time if the ball is dropped. There is no concept of tagging up under the intentional drop rule, as base advances are not allowed.

Hit runners

A runner hit by an infield fly while standing on a base is also protected from being declared out due to interference, unless this interference is deemed intentional (which appeared in the rules in 1940).

Rule not declared

The rulebook definition of Infield Fly says the umpire "shall immediately declare 'Infield Fly' for the benefit of the runners." However, sometimes they do not. As in the anecdote above from 2008, there may be doubt as to whether the ball was catchable by an infielder with ordinary effort. If not called, the infield fly rule is not in effect. The same Definition includes a comment that "The infield fly is in no sense to be considered an appeal play." This suggests that the batter cannot be ruled out retroactively to settle a debate that occurs after the play ends. However, in Major League Baseball, the umpires are likely to correct their mistake if it leads to an unfair double or triple play. Baserunners should learn what options they have, both on a routine fly out and a fly out declared an infield fly. Fielders should understand that declaration of the infield fly rule removes the force play and that a runner is only out if tagged.

Batter passing another runner

In adult baseball, a fly ball usually reaches the fielder before the batter can run the 90 feet to first base. However, in youth baseball, the distance between bases is shorter, and in some youth leagues, the infield fly rule is not in effect.

In this case, a base running gambit can be used to avoid a double or triple play. A fast batter may reach first base before the pop fly reaches the fielder. If the fielder fails to catch the ball, then the batter runs toward second base while the runner originally on first base remains there. Under Rule 7.08(h), the batter is out for passing a preceding runner, and under Rule 7.08(c), this out removes the force so that other runners are able to remain on their bases.

The infield fly rule and legal theory

The infield fly rule was the subject of an article in U.S. legal history. William S. Stevens was a law student in 1975 when he anonymously published "The Common Law Origins of the Infield Fly Rule" in the University of Pennsylvania Law Review. The article was humorous but also insightful on how common law related to codified regulation of behavior. It has been cited in numerous legal decisions and in subsequent literature.

Outline

SPORTS WORLD

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

SPORTS WORLD

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.
