Stolen base
In baseball, a stolen base occurs when a runner advances to a base unaided by other actions and the official scorer rules that the advance should be credited to the action of the runner. The umpires determine whether the runner is safe or out at the next base, but the official scorer rules on the question of credit or blame for the advance under Rule 10 of the MLB's Official Rules.
A stolen base most often occurs when a base runner advances to the next base while the pitcher is pitching the ball to home plate.
Background
, playing for the Philadelphia Keystones in either 1863 or 1865, was the first player to steal a base in a baseball game, although the term stolen base was not used until 1870. For a time in the 19th century, stolen bases were credited when a baserunner reached an extra base on a base hit from another player. For example, if a runner on first base reached third base on a single, it counted as a steal. In 1887, Hugh Nicol set a still-standing Major League record with 138 stolen bases, many of which would not have counted under modern rules. Modern steal rules were fully implemented in 1898.Image:MLB HR and SB rates.png|thumb|Graph depicting the yearly number of home runs and stolen bases per MLB game.

Base stealing was popular in the game's early decades, with speedsters such as Ty Cobb and Clyde Milan stealing nearly 100 bases in a season. But the tactic fell into relative disuse after Babe Ruth introduced the era of the home run - in 1955, for example, no one in baseball stole more than 25 bases, and Dom DiMaggio won the AL stolen base title in 1950 with just 15. However, in the late 1950s and early 1960s, base-stealing returned to prominence primarily thanks to Luis Aparicio and Maury Wills, who broke Cobb's modern single-season record by stealing 104 bases in 1962. In turn, Lou Brock broke Wills’ record in 1974, as did Rickey Henderson in 1982. The stolen base remained a popular tactic through the 1980s, perhaps best exemplified by Vince Coleman and the St. Louis Cardinals, but began to decline again in the 1990s as the frequency of home runs reached record heights and the steal-friendly artificial turf ballparks began to disappear.
Base stealing is an important characteristic of the "small ball" managing style. Such managers emphasize "doing the little things" to advance runners and score runs, often relying on pitching and defense to keep games close. The Los Angeles Dodgers of the 1960s, led by pitcher Sandy Koufax and speedy shortstop Maury Wills, were a successful example of this style. The antithesis of this is reliance on power hitting, exemplified by the Baltimore Orioles of the 1970s, who aspired to score most of their runs via home runs. Often the "small ball" model is associated with the National League, while power hitting is associated with the American League. However, some successful recent American League teams, including the 2001 Seattle Mariners, 2002 Anaheim Angels, the 2005 Chicago White Sox, and the 2015 Kansas City Royals, have excelled at "small ball." The Royals in particular embodied this style within the 2010s, leading the league in stolen bases but finishing last in home runs in 2013 and 2014, leading to a berth in two consecutive World Series, the second of which they won in 2015. Successful teams often combine both styles, with speedy runners complementing power hitters—such as the 2005 champion White Sox, who hit 200 home runs, which was fifth most in the majors, and stole 137 bases, which was fourth.
Base-stealing technique
Baseball's Rule 8 specifies the pitching procedure in detail. For example, in the Set Position, the pitcher must "com to a complete stop"; thereafter, "any natural motion associated with his delivery of the ball to the batter commits him to the pitch without alteration or interruption." A runner intending to "steal on the pitcher" breaks for the next base the moment the pitcher commits to pitch to home plate. The pitcher cannot abort the pitch and try to put the runner out; this is a balk under Rule 8.If the runner breaks too soon, the pitcher may throw to a base rather than pitch, and the runner may be tagged out between the bases. Past this moment, any delay in the runner's break makes it more likely that the catcher, after receiving the pitch, will be able to throw the runner out at the destination base.
Before the pitch, the runner takes a lead, walking several steps away from the base as a head start toward the next base. Even a runner who does not intend to steal takes a secondary lead of a few more steps, once the pitcher has legally committed to complete the pitch.
The pitcher may throw to the runner's base. The runner must return to that base or risk being tagged out. As well as putting the runner out, an underlying goal is to dissuade the runner from too big a lead; that is, to hold the runner on the original base.
The more adept base stealers are proficient at reading the pickoff, meaning that they can detect certain tells in a pitcher's pre-pitch movements or mannerisms that indicate the pickoff attempt is or is not imminent. For example, one experienced base stealer noted that careless pitchers dig the toes of their back foot into the ground when they are about to pitch in order to get a better push off, but when they intend to turn and throw a pickoff, they do not.
If a batted ball is caught on the fly, the runner must return to his original base. In this case, a runner trying to steal is more likely to be caught off his original base, resulting in a double play. This is a minor risk of a steal attempt. It is offset by the fact that a ground ball double play is less likely.
Plays involving baserunning
In the hit-and-run play, coaches coordinate the actions of runner and batter. The runner tries to steal and the batter swings at almost any pitch, if only to distract the catcher. If the batter makes contact, the runner has a greater chance of reaching the next base; if the batter gets a base hit, the runner will likely be able to take an extra base. If the batter fails to hit the ball, the hit-and-run becomes a pure steal attempt.The less common cousin to the hit and run is the "run and hit" play. In the run and hit, the base runner attempts to advance when the pitcher commits the pitch to home plate, but the batter is instead directed to exercise his judgement as to whether or not to swing at the pitch. If the batter feels it is not advantageous to swing, AND he believes the base runner is very likely to succeed in the steal attempt, he does not swing. This play is typically utilized with elite base stealers and skilled batters only, wherein a highly experienced batsman is trusted to decide whether or not to "protect" the base runner. If the batter chooses not to swing, it becomes a pure steal attempt.
In the delayed steal, the runner does not take advantage of the pitcher's duty to complete a pitch, but relies on surprise and takes advantage of any complacency by the fielders. The runner gives the impression he is not trying to steal, and does not break for the next base until the ball crosses the plate. It is rare for Major League defenses to be fooled, but the play is used effectively at the college level. The first delayed steal on record was performed by Miller Huggins in 1903. The delayed steal was famously practiced by Eddie Stanky of the Brooklyn Dodgers.
Second base is the base most often stolen, because once a runner is on second base he is considered to be in scoring position, meaning that he is expected to be able to run home and score on most routine singles hit into the outfield. Second base is also the easiest to steal, as it is farthest from home plate and thus a longer throw from the catcher is required to prevent it. Third base is a shorter throw for the catcher, but the runner is able to take a longer lead off second base and can leave for third base earlier against a left-handed pitcher. A steal of home plate is the riskiest, as the catcher only needs to tag out the runner after receiving the ball from the pitcher. It is difficult for the runner to cover the distance between the bases before the ball arrives home. Ty Cobb holds the records for most steals of home in a single season as well as for a career. Steals of home are not officially recorded statistics, and must be researched through individual game accounts. Thus Cobb's totals may be even greater than is recorded. Jackie Robinson famously stole home in Game 1 of the 1955 World Series. Thirty-five games have ended with a runner stealing home, but only two have occurred since 1980. In a variation on the steal of home, the batter is signaled to simultaneously execute a sacrifice bunt, which results in the squeeze play. The suicide squeeze is a squeeze in which the runner on third begins to steal home without seeing the outcome of the bunt; it is so named because if the batter fails to bunt, the runner will likely be out, unless he successfully steals home. In contrast, when the runner on third does not commit until seeing that the ball is bunted advantageously, it is called a safety squeeze.
In more recent years, most steals of home involve a delayed double steal, in which a runner on first attempts to steal second, while the runner on third breaks for home as soon as the catcher throws to second base. If it is important to prevent the run from scoring, the catcher may hold on to the ball or may throw to the pitcher; this may deceive the runner at third and the pitcher may throw back to the catcher for the out.
Statistics
In baseball statistics, stolen bases are denoted by "SB". Attempts to steal that result in the baserunner being out are caught stealing. The sum of these statistics is steal attempts. Successful steals as a percentage of total steal attempts is called the success rate.The rule on stolen bases states that:
- Advances that are credited to some other play are not steal attempts. For example, on a wild pitch or a passed ball, the official scorer must notice whether the runner broke for the next base before the pitch got away.
- As usual, statistics in the case of a defensive error are based on error-free play. If a runner would have been out, but for the error, it is scored as "caught stealing, safe on the error." A catcher does not commit an error by throwing poorly to the destination base, but if any runner takes an extra base on the bad throw, it is "stolen base plus error."
- There is no steal attempt on a dead ball, whether the runner is sent back to the original base or is awarded the next base. On a base award when the ball is live, the runner could make a steal attempt beyond the base awarded.
- Cases where the defense intentionally allows the runner to advance without attempting to put him out are scored as defensive indifference, also called fielder's indifference, and do not count as stolen bases. This is usually only scored late in games when it is clear that the defense's priority is getting the batter out. The lack of a putout attempt does not by itself indicate defensive indifference; the official scorer must also factor in the game situation and the defensive players' actions.
Comparing skill against players from other eras is problematic, because the definition has not been constant. Caught stealing was not recorded regularly until the middle of the 20th century. Ty Cobb, for example, was known as a great base-stealer, with 892 steals and a success rate of over 83%. However, the data on Cobb's caught stealing is missing from 12 seasons, strongly suggesting he was unsuccessful many more times than his stats indicate. Carlos Beltrán, with 286 steals, has the highest career success rate of all players with over 300 stolen base attempts, at 88.3%.
