All four players were drafted or originally signed as amateurs by the Yankees in the early 1990s. They played together in the minor leagues, and made their Yankee major league debuts in 1995. Each of them was a key contributor to the Yankees' late-1990s dynasty that won four World Series championships in five years. By 2007, they were the only remaining Yankees from the franchise's dynasty of the previous decade. All four players were on the Yankees' active roster in 2009 when the team won the 2009 World Series—its fifth championship in the previous 14 years.
