See main article: 2021 Little League World Series. The results of the 2021 Little League World Series were determined during August 19–29, 2021, in South Williamsport, Pennsylvania. A total of 16 teams from the United States were divided into two groups of eight teams, with both groups playing a modified double-elimination tournament. In each group, the last remaining undefeated team faced the last remaining team with one loss, with the winners of those games advancing to play for the Little League World Series championship.[1] The two eight-team tournament brackets were named after Major League Baseball players and National Baseball Hall of Fame inductees Hank Aaron and Tom Seaver, who died in January 2021 and August 2020, respectively.
