When Derek Jeter finally changes position from shortstop to something else (no longer a matter of "if" no matter what his two home run game this past Sunday makes you think), he won't be setting a historical precedent by doing so.
Throughout baseball history, there are a lot of players that changed positions after the age of 35. Some continued to play into their 40s while some were done within a couple of years.
The following is a list of the 25 best players in baseball history who made a position change from the age of 35 or after.
In order to be considered, the player had to play a different position as their primary position after they turned 35 than the one they played when they were 34. If the player was a right fielder at the age of 34 and then were mainly a first baseman when they were 35; they were eligible. If the player was still mainly a right fielder with just occasionally a game at first base; they weren't eligible. This list includes 22 such players.
I also included three players who weren't 35 years old when they made the position change but were either able to continue playing at the age of 34 only because of the position change (two players in this category) and one player who made a significant change at 30 years old (they were arguably the best in the game at their position when they were 29, only to find themselves in a new position at the age of 30).
This list is in no particular order and begins with the inspiration for this article, Derek Jeter.
