User:Muboshgu/Core Four

The Core Four is a nickname given to Derek Jeter, Mariano Rivera, Jorge Posada, and Andy Pettitte, who combined to win five World Series championships with the New York Yankees from 1996 to the present.

All four joined the Yankees organization in the early 1990s. Rivera signed as a free agent in February 1990. Pettitte was the 22nd round pick of the Yankees in the 1990 Major League Baseball Draft. Jeter was selected in the first round of the 1992 Major League Baseball Draft.

All four made their major league debuts in 1995.

On April 6, 2010, Jeter, Posada and Rivera became the first teammates in any of the four major league sports in North America (MLB, NFL, NBA, or NHL) to play in at least 16 seasons on the same team as teammates.

On February 4, 2011, Pettitte became the first member of the Core Four to retire. The remaining members are the "Key Three".
