Baseball5 (B5) is a variation of the game of baseball which does not involve bats or gloves. [1] There is no pitcher, with the batter instead starting each play with possession of the rubber ball, which they hit with their bare hand. There are five players on each team and each team has five innings. [2] The World Baseball Softball Confederation proposed the game in 2018. [3]


Rules and gameplay


Baseball5 field.jpg

The infield has a square shape, with a base in every corner. The distance between bases is 13 metres (43 ft). The fair territory has a square shape of 18 metres (59 ft) per side, in which one of the corners coincides with the home plate. The batter’s box has a square shape of 3 metres (9.8 ft) per side. It is placed outside of the fair territory and is built on the extension of the two foul lines crossing each other at the home plate corner.

Ideal shape and size of all bases is a square of 50 centimetres (20 in) per side. In order to avoid collisions, the first base is "double". The ideal height of the fences is 1 metre (3.3 ft). However, every league or tournament organisation may decide on other ways of limiting the field of play, such as using existing walls or marking the ground.


Baseball5 hitting Cuba Baseball5 game.jpg
Baseball5 hitting

The act of hitting takes place while a hitter is entirely in the batter's box and shall remain within the lines until the hit ball gets into fair territory. The ball has to be hit hard either with a palm or a fist. The first bounce has to be at a minimum distance of 3 metres (9.8 ft) from home plate. The batter in the action of running towards first base, after putting the ball in play, has to touch the base. In order to stay safe, the batter has to remain in the area included within the base and the 1.5 metres (4.9 ft)-meter safe area attached to it.

How the offensive players eliminate themselves due to illegal behaviors/actions:

In a situation with bases loaded and two outs, if the runner at third base has to be the next hitter in the batting order, the runners at first and second bases each advance one base, the runner on third base goes to hit, and a pinch runner is placed on first base. In teams with only five players, the first player called out in that inning becomes pinch runner on first base. The batting order shall always be respected.

The five players (1st Base, 2nd Base, 3rd Base, Shortstop and Midfielder) of the defensive team shall all be in fair territory when the batter hits the ball. The defensive team shall eliminate three opponents in each inning so as to switch sides and become the offensive team.

How the defense makes "outs":

If the ball leaves the court due to a defensive error (missed throw or missed catch), each runner is awarded an extra base.

End of the game

The game ends at the end of the fifth inning if one team has scored more runs than the opponent. Should the Home Team be ahead on the score after the Guest Team has completed its fifth offensive inning, the game is over and the Home Team wins.

In case of a tie game, the teams shall play and complete extra inning(s) until one team scores more runs than the opponent. The player scheduled to hit fifth for the sixth inning is placed on first base as a runner to start the inning. The players scheduled to hit fifth and fourth in the seventh inning are placed on first and second base, and so on with three runners to start the following innings until the game ends.

A game is over if a team leads by 15 runs at the end of the third inning or by 10 at the end of the fourth. Should a team reach a 10-run (or more) advantage during the top of the fifth inning, the game shall be completed.

Base on balls In baseball, reaching base on four balls

A base on balls (BB), also known as a walk, occurs in baseball when a batter receives four pitches that the umpire calls balls, and is in turn awarded first base without the possibility of being called out. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08(a). It is considered a faux pas for a professional player to literally walk to first base; the batter-runner and any advancing runners normally jog on such a play.

Hit (baseball) In baseball, hitting the ball into fair territory and safely reaching base without the benefit of an error or fielders choice

In baseball statistics, a hit, also called a base hit, is credited to a batter when the batter safely reaches or passes first base after hitting the ball into fair territory, without the benefit of an error or a fielder's choice.

Baseball team sport

Baseball is a bat-and-ball game played between two opposing teams who take turns batting and fielding. The game proceeds when a player on the fielding team, called the pitcher, throws a ball which a player on the batting team tries to hit with a bat. The objective of the offensive team is to hit the ball into the field of play, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called "runs". The objective of the defensive team is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate. The team that scores the most runs by the end of the game is the winner.

Home run In baseball, a four-base hit resulting in a run by the batter

In baseball, a home run is scored when the ball is hit in such a way that the batter is able to circle the bases and reach home safely in one play without any errors being committed by the defensive team in the process. In modern baseball, the feat is typically achieved by hitting the ball over the outfield fence between the foul poles without first touching the ground, resulting in an automatic home run. There is also the "inside-the-park" home run where the batter reaches home safely while the baseball is in play on the field.

Rounders Bat-and-ball team sport originating in England

Rounders is a bat-and-ball game played between two teams. Rounders is a striking and fielding team game that involves hitting a small, hard, leather-cased ball with a rounded end wooden, plastic, or metal bat. The players score by running around the four bases on the field.

Softball Team ball sport

Softball is a game similar to baseball played with a larger ball on a field that has base lengths of 60 feet, a pitcher's mound that ranges from 35 to 43 feet away from home plate, and a home run fence that is 220–300 feet away from home plate, depending on the type of softball being played. It was invented in 1887 in Chicago, Illinois, United States as an indoor game. The game moves at a faster pace than traditional baseball due to the field being smaller and the bases and the fielders being closer to home plate. There is less time for the base runner to get to first while the opponent fields the ball; yet, the fielder has less time to field the ball while the opponent is running down to first base.

In many team sports, defense or defence is the action of preventing an opponent from scoring. The term may also refer to the tactics involved in defense, or a sub-team whose primary responsibility is defense. Similarly, a defense player or defender is a player who is generally charged with preventing the other team's forwards from being able to bear down directly on their own team's goalkeeper or goaltender. Such positions exist in association football, ice hockey, water polo and many other sports.

Out (baseball)

In baseball, an out occurs when the umpire rules a batter or baserunner out. When a batter or runner is out, they return to the dugout until their next turn at bat. When three outs are recorded in a half inning, the batting team's turn expires.

Over-the-line is a bat-and-ball sport, a game related to baseball and softball. Like those games, you have the batter, pitcher, and fielders. Because a game requires only three people per team, it is considerably easier to get a good informal game going. Equipment consists of a rope, an "official" softball bat & a "official" Orange rubber DeBeer softball. No gloves are allowed while fielding in the Men's divisions unless 60+ years of age.

Baseball scorekeeping

Baseball scorekeeping is the practice of recording the details of a baseball game as it unfolds. Professional baseball leagues hire official scorers to keep an official record of each game, but many fans keep score as well for their own enjoyment. Scorekeeping is usually done on a printed scorecard and, while official scorers must adhere precisely to one of the few different scorekeeping notations, most fans exercise some amount of creativity and adopt their own symbols and styles.

The Knickerbocker Rules are a set of baseball rules formalized by William R. Wheaton and William H. Tucker of the Knickerbocker Base Ball Club in 1845. They have previously been considered to be the basis for the rules of the modern game, although this is disputed. The rules are informally known as the "New York style" of baseball, as opposed to other variants such as the "Massachusetts Game" and "Philadelphia town ball".

Ground rules

In baseball, ground rules are special rules particular to each baseball park (grounds) in which the game is played. Unlike the well-defined playing field of most other sports, the playing area of a baseball field extends to an outfield fence in fair territory and the stadium seating in foul territory. The unique design of each ballpark, including fences, dugouts, bullpens, railings, stadium domes, photographer's wells and TV camera booths, requires that rules be defined to handle situations in which these objects may interact or interfere with the ball in play or with the players.

Bat-and-ball games Field games played by two opposing teams

Bat-and-ball games are field games played by two opposing teams, in which the action starts when the defending team throws a ball at a dedicated player of the attacking team, who tries to hit it with a bat and run between various safe areas in the field to score points, while the defending team can use the ball in various ways against the attacking team's players to prevent them from scoring when they are not in safe zones. The best known modern bat-and-ball games are cricket and baseball, with common roots in the 18th-century games played in England.
