in the summer months leading up to the little league world series, held each year in august, little leagues around the world select an all-star team made up of players from its league. it is these all-star teams that compete in district, sectional and/or divisional, and regional tournaments, hoping to advance to williamsport for the little league world series. how many games a team has to play varies from region to region. in the united states, the tournaments at the lowest (district) level lack nationwide standardization. some use pool play or double elimination, while others use single elimination.
