Little League World Series (Southwest Region)
The Southwest Region is one of eight United States regions that currently send teams to the Little League World Series, the largest youth baseball competition in the world. The region's participation in the LLWS dates back to 1957, when it was known as the South Region. However, when the LLWS was expanded in 2001 from eight teams to 16 teams, the Southern Region was split into the Southeast and Southwest Regions.
Regional headquarters are located in Waco, Texas.
The Southwest Region is made up of eight districts in seven states.
