Last week, New York Yankees shortstop Derek Jeter announced that he would retire at the end the 2014 baseball season after 20 years in baseball. The Yankees captain and future first ballot Hall of Fame candidate has been a fixture in the New York lineup since 1996, playing an average of 144 games per season; that figure jumps to 153 if you discount his injury-plagued 2013 campaign in which he managed just 17 games due to injury.
His career appearances at shortstop is by and far the most by a player in a Yankees uniform; Phil Rizzuto is a distant second with 1647 appearances, while Frankie Crosetti is third with 1516. He has also played the most games of anyone in a Yankees uniform, 2602, which is over 200 more than the great Mickey Mantle.
In contrast, over the same time period, the shortstop position has been remarkably fluid for the Boston Red Sox, especially since 2004 when the team traded away perennial All-Star Nomar Garciaparra to the Chicago Cubs at the deadline. Since 2005, no player has held that role for longer than two seasons and only one player has started at least 150 games in a single season.
