The WBSC claims the rapid global expansion of Baseball5, which will be making its Youth Olympic Games debut in Senegal's capital Dakar in 2022, has pushed the evolution and standardisation of the new rules, optimising it for further growth.

"The updated rules, adjustments and optimisation to the young Baseball5 discipline reflect its rapid rise and global adoption – and the need for standardisation – with already over 70 countries across all five Olympic continents now practicing this new, youth-targeted game," WBSC President Riccardo Fraccari said.

New regulations in the 16-page rule book include an expanded "no hit" zone in front of the home plate and an official line-up card.

The 2020 edition of the rule book is divided into four main chapters: the field, game preliminaries, game rules and end of the game.

Baseball5 can be played anywhere – on all terrains – and requires only a rubber ball, which weighs 84.8 grams and has a diameter of 66.4 millimetres.

The Baseball5 infield has a square shape, and the distance between the bases is 13 metres.

The number of active players per team during a game is five at all times, while the maximum number of players on a team roster is eight.

General urban sports attire is required for playing official WBSC-sanctioned competitions.

For any instance not covered by the WBSC Baseball5 rule book, officials will refer to the official baseball rules.

The first-ever Baseball5 World Cup and Youth Baseball5 World Cup are due to take place in Mexico in December.

The WBSC has recently confirmed the continental quota. 

WBSC Europe will organise the first official continental championship in Lithuania's capital Vilnius from February 28 to March 1.

It has been confirmed that the 16 competing teams will be split into four groups during the competition's first stage, which will be followed by a single elimination format.
