Little League Baseball and Softball (officially,Little League Baseball Inc[1]) is a501(c)(3)nonprofit organization[2][3] based inSouth Williamsport, Pennsylvania, United States, that organizes local youthbaseball andsoftballleagues throughout the United States and the rest of the world.
Founded byCarl Edwin Stotz (1910–1992), in 1939 as a three-team league in the adjacent larger town ofWilliamsport, Pennsylvania. The ensuing Little League organization was incorporated on October 10, 1950, and Stotz served as first commissioner for 18 years until 1955.[1] Little League Baseball encourages local volunteers to organize and operate Little League franchise programs that are annually chartered through Little League International. Each local league can structure itself to best serve the children in the area in which the league operates. Several specific divisions of Little League baseball and softball are available to children and adolescents ages 4 to 16. The organization holds acongressional charter authorized by theUnited States Congress underTitle 36 of the United States Code.[4]
The organization's administrative office is located in South Williamsport of Lycoming County, Pennsylvania. The first Little League Baseball World Series was played in Williamsport in 1947. The Little League International Complex in South Williamsport hosts the annual tournament of theLittle League Baseball World Series atHoward J. Lamade Stadium and adjacentLittle League Volunteer Stadium, and is also the site of thePeter J. McGovern Little League Museum, which provides a history of Little League Baseball and Softball through interactive exhibits for children. ManyMajor League Baseball (MLB) players past and present in theNational League andAmerican League have started out playing in their local community / neighborhood Little Leagues.

Carl Edwin Stotz (1910–1992), a longtime resident of Williamsport, Pennsylvania, founded Little League Baseball in 1939. He began experimenting with his idea in the summer of 1938 when he gathered his nephews, Jimmy and Major Gehron, and their neighborhood friends. They tried different field dimensions over the course of the summer and played several informal games. The following summer, they felt that they were ready to establish what later became Little League Baseball. The first small league organized in Williamsport had just three teams, each sponsored by a different business. The first teams, Jumbo Pretzel, Lycoming Dairy, and Lundy Lumber Company were managed by Stotz and his friends, George and Bert Bebble. The men, joined by their wives and another couple, formed the first Little League board of directors.[6]
The first league game took place on June 6, 1939, when Lundy Lumber defeated Lycoming Dairy, 23–8. Lycoming Dairy became the champions of the first half of the season and then defeated Lundy Lumber, the second-half champions, in a best-of-three championship series. The following year, a second league was formed in Williamsport, and Little League Baseball grew to become an international organization with nearly 200,000 teams in every U.S. state and more than 80 countries.[6]
Kathryn "Tubby" Johnston Massar was the first woman to play in a Little League baseball game, in 1950.[7][8] However, when that season ended, a Little League meeting was held, and it was decided that girls would be banned from Little League baseball.[9] From 1951 through 1973, Little League baseball was restricted toboys only. In 1974, due to a lawsuit brought on behalf ofMaria Pepe by theNational Organization for Women, theNew Jersey Superior Court decided that Little League baseball must allow girls to play.[10][11] In the final week of December 1974, PresidentGerald Ford, signed a bill that opened Little League baseball to girls.[12]
According to the Little League Baseball and Softball participation statistics following the 2008 season, there were nearly 2.6 million boys and girls in Little League Baseball worldwide. Of these, approximately 400,000 are registered in softball leagues (including both boys and girls). Starting in 2022, for tournament purposes, Little League Baseball was divided into 20 geographic regions: ten national and ten international. Each summer, Little League operates seven World Series tournaments in various locations throughout the U.S. (Little League softball and Junior, Senior, and Big League baseball and softball).

1950 Kay Johnston becomes the first girl to play Little League baseball. She cuts her hair, dresses as a boy and adopts the nickname "Tubby" to join the Kings Dairy Little League team inCorning, New York as a boy.[14] After earning her way onto the team and being assigned first base, she tells her coach that she is a girl, but he keeps her on the team. She is forced to quit after just one season because a new rule, known as the Tubby Rule, is created to bar girls from participation. The rule remains in force until 1974.[15][16]
1951: Leagues are formed in the western province on the Pacific Ocean coast ofBritish Columbia, in the neighboringDominion of Canada to the north and in the old U.S. territory of thePanama Canal Zone surrounding thePanama Canal, inCentral America, making them the first youth baseball leagues outside the United States.[6]

The league consisted of four teams, sponsored by prominent black businesses inCharleston, South Carolina.[17] In 1955, in the beginnings of the growing nation-wideCivil rights movement, when, Morrison entered his Cannon Street All-Stars into the city tournament, white leagues reacted by drafting a resolution requesting a whites-only tournament. All 55 white teams eventually withdrew from the city and state tournament. The Cannon Street All-Stars became the 1955 South Carolina state champions by forfeit. However, they were informed by then national Little League Baseball president Peter J. McGovern that they would not be permitted to represent the state at the regional championships in Williamsport. Little League executives invited the Cannon Street All-Stars as guests to attend the tournament in which they were barred from playing.[17]

After white teams inSouth Carolina refuse to play against the all-black Cannon Street YMCA All-Stars ofCharleston, Little League issues an ultimatum that the team must be permitted to play, but many organizations in theSouthern United States suspend and turn in their league charters and form their own league in response.[18] No team from South Carolina would reach the World Series tournament until 2015.
1956: Stotz severs his ties with Little League Baseball, Inc. after 18 years in a dispute over the direction, policies and control of the league. Stotz believed that the league was becoming overly commercialized by then-president Peter J. McGovern.[19] Stotz remains active in youth baseball with the "Original League" in Williamsport for the next 38 years until his death in June 1992.[6] Little League records its first on-field death inGarland, Texas, when 12-year-old Richard Oden is hit in the head by a pitch, and the park where the incident occurred is renamed Rick Oden Field.[20] With batting helmets yet to be developed, Garland League teams finish the season wearing youth football helmets over their baseball caps when batting. Later in the year, pitcher Fred Shapiro throws a perfect game in the Little League World Series.

Little League Baseball has several baseball divisions based on age.[55]
The major divisions of Little League Baseball have their own World Series format as follows:
| Division | Location | First held | Age of players | Series |
|---|---|---|---|---|
| Little League Baseball | South Williamsport, Pennsylvania | 1947 | 9–12 years old | Little League World Series |
| Intermediate League Baseball | Livermore, California | 2013 | 11–13 years old | Intermediate League World Series |
| Junior League Baseball | Taylor, Michigan | 1981 | 13–14 years old | Junior League World Series |
| Senior League Baseball | Easley, South Carolina | 1961 | 14–16 years old | Senior League World Series |
| Big League Baseball | Easley, South Carolina | 1968 | 16–18 years old | Big League World Series (discontinued after 2016) |
Tee-ball is for boys and girls ages 4–7. In tee-ball, players hit the ball off of a tee located atophome plate; live pitching is not allowed. The purpose of the division is to teach young children the fundamentals of hitting and fielding.[55]
The minor league baseball division is generally for children ages 5–11, with local leagues given the option to allow 6-year-old children to try out. Local leagues are permitted to further divide the Minor League division based on player age and/or experience, and often consist of coach-pitch (i.e., the batter's coach lightly pitching the ball) or machine-pitch at lower levels, with defensive players pitching at higher levels.[55]
The 9–10-year-old baseball division is a tournament program, established in 1994. It has competitions up to the state level, and the size of the diamond is the same as in the Little League division (with 60-foot (18 m) sides and a 46-foot (14 m) pitching distance).[55]
The Little League Baseball division, also known as the Major Division, is for children aged 9 through 12, though local leagues have the option of barring 9 or 10 year olds from participating. The diamond has base paths measuring 60-foot (18 m) and a pitching distance of 46-foot (14 m). The local league can form an "All Stars" team consisting of players throughout the local teams, which can enter an international tournament culminating with theLittle League World Series.[55]
In 2012, Little League announced plans to add a new division of play for the 2013 season, the Little League Intermediate Division. This division is played on a field with a 50-foot (15 m) pitching distance and 70-foot (21 m) base paths. It is open to players ages 11–13, but may be limited to ages 11–12 or 12–13 by a local league. Players in this division are able tolead off andsteal bases. The rules are similar to those of the Junior, Senior, and Big League divisions of play.
Little League holds a World Series in this level of play, officially called theIntermediate Little League World Series, inLivermore, California.[56]
The Junior League, Senior League, and Big League Baseball divisions operate similarly for different age groups. All three use a conventionally-sizedbaseball diamond, with 90 feet (27 m) between bases and a 60 feet 6 inches (18.44 m) pitching distance. Similarly to the Major Division, local leagues can form "All Stars" teams from each age group and enter a tournament, again leading up to a "World Series", for each division. The Junior League consists of 12–14 year olds, the Senior League consists of 13–16 year olds, and the Big League was for 16–18 year olds.[55] The Big League division was eliminated after the 2015–2016 season.[57]
Little League introduced the Challenger Division in 1989 to provide opportunities for children with physical and intellectual challenges to participate in the Little League program. The Challenger Division utilizes a "buddy system" in which Little Leaguers assist Challenger participants in the areas of batting, running and fielding. Challenger Division games are typically non-competitive in nature.[58]
Introduced in 1989, the Little League Challenger Division is for participants ages 4–18. Games are played on a 46/60 field and are non-competitive.
Approved at the 2014 Little League International Congress, the Senior League Challenger Division launched in 2015. This division is for participants ages 15 and above (no maximum age). Games are played on a 60/90 field and are non-competitive. Leagues may request permission to play games on a smaller field as well.
As of 2018, nearly 1,000 Little Leagues in 10 countries around the world offer the Challenger Program, providing an opportunity for more than 31,000 individuals with physical or intellectual challenges to participate in the Little League program.
Little League Baseball has several softball divisions for girls and boys, based on age.
| Division | Location | First Held | Age of players | Series |
|---|---|---|---|---|
| Little League Softball | Greenville, North Carolina | 1974 | 9–12 years old[59] | Little League World Series (softball) |
| Junior League Softball | Kirkland, Washington | 1999 | 12–14 years old[59] | Junior League World Series (softball) |
| Senior League Softball | Sussex County, Delaware | 1976 | 13–16 years old[59] | Senior League World Series (softball) |
| Big League Softball | Kalamazoo, Michigan | 1982 | 14–18 years old[59] | Big League World Series (softball) (Division discontinued in 2016) |
Playing rules for the baseball divisions essentially follow theofficial baseball rules defined and used byMajor League Baseball, especially with respect to the upper divisions (Junior, Senior). Some major exceptions are outlined in the following sections, and these apply to Little League (Minor and Major, ages 7–12) except as otherwise noted.
The official rules of Little League Baseball are available to the general public via a free app or as a $5 printed edition.[63] In Canada, rulebook orders requested through LittleLeague.ca are routed to the US website at the same prices.[64]
Rulebooks are not available in stores and must be ordered directly from Little League Baseball or from one of its regional centers.[63][65] One paper copy is provided to each chartered team.[63]
A regulation game consists of sixinnings. If the game is halted prior to the completion of six innings, it is considered an official game if four innings have been completed (three and a half, if the home team leads); otherwise, if at least one inning has been completed, it is a suspended game.
In Intermediate Little League, as well as the Junior, Senior, and Big League levels (ages 13–18), a game consists of seven innings and is official if five innings have been completed.
In all divisions except Senior and Big League, every player on the team roster must have at least one plate appearance and play six consecutive outs on defense in each game. The penalty for a manager violating the rule is a two-game suspension. This rule is waived if the game is completed prior to the usual duration (six innings in Little League and below, seven innings in Intermediate Little League and Junior League). This rule is modified during tournament play, when teams having 13 or more players dressed are mandated to provide one plate appearance for each player, but have no defensive requirements. Teams having 12 or fewer players dressed are required to afford each player one plate appearance plus six consecutive outs in the field on defense.
The size of the field is dependent on the division of play.[66]
Tee-ball
Minor League and Little League

Junior League, Senior League, and Big League
Bats (all levels) may be made from wood or other materials (such asaluminum) and must be approved for use in Little League Baseball. For the Majors division and below, the maximum bat length is 33 inches (838 mm) and barrel diameter may not exceed2+1⁄4 inches (57 mm). Since 2009, all Little League bats must be labeled with a Bat Performance Factor (BPF) of 1.15 or lower.
Bats for the Junior League level may have a maximum length of 34 inches (864 mm) and a maximum barrel diameter of2+5⁄8 inches (67 mm). Bats for the Big and Senior League levels may have a maximum length of 36 inches (914 mm) and a maximum barrel diameter of2+5⁄8 inches (67 mm). Non-wood Big and Senior League bats must meet the Batted Ball Coefficient of Restitution (BBCOR) testing standards that are currently used in theNCAA andNFHS (high school).[67] Intermediate Little League bats must meet Junior League specifications.
When the pitcher is ready to pitch, a baserunner may not leave the base until the pitch reaches the batter in Minor League and standard Little League. In the upper levels, including Intermediate Little League, the runner may leave the base at any time while the ball is in play.
If a fielder is waiting at the base with the ball, an advancing runner must attempt to avoid contact. A runner may not slide head-first except when retreating to a previously held base.
In the upper levels, runners must still make an attempt to avoid contact if possible, and may not maliciously initiate contact with a fielder.
The upper limit of thestrike zone extends to the batter's armpits.[68]
In tee-ball, Minor League, and Little League (if theuncaught third strike rule is waived by the local league), the batter is out after thethird strike regardless of whether the pitched ball is held by the catcher. In Little League (both standard and Intermediate), Junior, Senior, and Big League, a batter may attempt to advance to first base on a dropped third strike if first base is unoccupied with less than two outs, or if first base is unoccupied or occupied with two outs.
If the batter is hit by a pitch, the batter receives abase on balls automatically. However, if the batter does not make an attempt evade the pitched ball, the home-plate umpire may continue the at-bat.
Players who have been substituted may return to the game under certain conditions, though a player who is removed as pitcher may not return to pitch.
Pitchers in all divisions are limited to a specific pitch count per game and a mandatory rest period between outings. These vary with age. The rest period also depends on the number of pitches thrown.[69]
If the pitcher hits too many batters with the ball, or intentionally hits the batter, he or she is ejected from the pitching spot.
Historically, a pitcher couldintentionally walk a batter by simply announcing the intent to do so, without being required to throw any pitches. Beginning in 2008, the pitcher was required to actually pitch the required four balls (which are included in the pitcher's overall pitch count). In 2017, the Major and Minor levels of Little League Baseball aligned with an MLB rule and now allow the pitcher to intentionally walk a batter simply by declaration, though four pitches are added to the pitcher's overall pitch count.[70] This change rescinded a former rule by which the batting team could decline the award of first base and force the pitcher to throw four balls, thereby increasing the pitcher's overall count.[71]
Local leagues have a certain amount of flexibility. For example, a league may opt to use the "continuous batting order" rule (4.04), under which each player on the team's roster bats, even when not in the defensive lineup. Leagues may also waive the "ten-run rule" (4.10(e)), which ends the game if one team is ahead by ten or moreruns after four innings.[72][73]
