Little League World Series (Great Lakes Region)
The Great Lakes Region is one of eight United States regions that currently sends 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 Central Region. However, when the LLWS was expanded in 2001 from eight teams to 16 teams, the Central Region was split into the Great Lakes and Midwest Regions.
The Great Lakes Region has a unique definition that does not correspond with the normally understood definition of the "Great Lakes" area, even when the context is restricted to the U.S. Although eight U.S. states border on the Great Lakes, only five of the U.S. states are in Little League's Great Lakes Region:
One state that does not border any of the Great Lakes, and in fact has no territory within the Great Lakes watershed, is included in this region:
Two states that border on the Great Lakes, New York and Pennsylvania are part of the Mid-Atlantic region. The remaining U.S. state that borders on the Great Lakes, Minnesota, is in the Midwest region. All of Canada, including Ontario, forms a single Little League region.
