The Chicago Cubs won back-to-back World Series in 1907 and 1908.
Cincinnati Reds 1975 & 1976
Through the 2008 season, that was the New York Yankees who won the World Series in 1998, 1999, and 2000.
The New York Yankees (in 1998, 1999 and 2000) were the last MLB team to win consecutive World Series titles.
The Milwaukee Brewers have only appeared in one World Series, back in 1982 when they were in the American League. They lost to the St. Louis Cardinals of the National League in seven games.
By Junior Division I assume you mean what Little League calls the Junior League. I am afraid I cannot find that information. Little League's website, littleleague.org, has complete data for Central Region and Junior League World Series participants back through only the 2002 season. This year's team from Glendale is the only team I have found that has made the World Series. Teams from Wisconsin in the Central Region playoffs from 2002-2007 have come from Oak Creek, Franklin Little League, Whitefish Bay, Madison, and the last two years from Glendale. They list an email address of webmaster at littleleague.org to direct questions and comments. You might try contacting them to see if they have any information. The city of Taylor, Michigan, where the Junior League World Series is held, also has a website that has a section devoted to the World Series. Unfortunately, other than a list of past champions, there is no historical data to be found. They do list an email address to reach the World Series Director Greg Bzura (gregb at wwwnet.net) and Director of Public Information for both the City of Taylor and the World Series David Gorgon (taylornews at aol.com).
The Chicago Cubs won back to back World Series in 1907 and in 1908.
No team in the history of the World Series has ever rebounded to win from an 0-3 deficit.
There have been many, including Frank Robinson, the Most Valuable Player of the 1966 World Series, and Dusty Baker, who played on back-to-back National League champions in 1977 and 1978.
The Cubs won four pennants and two World Series titles over a five-year span. Although they fell to the "Hitless Wonders" White Sox in the 1906 World Series, the Cubs recorded a record 116 victories and the best winning percentage (.763) in Major League history. With mostly the same roster, Chicago won back-to-back World Series championships in 1907 and 1908. Their appearance in three consecutive World Series made the Cubs the first Major League club to play three times in the Fall Classic. Likewise, their back-to-back World Series victories in 1907 and 1908 made them the first club to win two World Series. However, the Cubs have not won a World Series since 1908; this remains the longest championship drought in North American professional sports.
