Each season begins with hope for the 30 MLB fan bases, and each one ends with disappointment for 29 of them. Every year, only one team can win the World Series, yet some supporters have waited a long time to see their club lift the Commissioner's Trophy. No club has won successive World Series victories since the New York Yankees in 1998, 1999, and 2000, the longest such streak in Major League Baseball history. Until 2002, home-field advantage in the World Series was shared by the National League and the American League.
