Following up on last weekend's chart of tenure for the current roster, we now look at player tenure for the entire franchise history. This is a little bit trickier to compile, and it's possible I might be missing the odd player. In which case use the comments to hold me accountable.

I find it interesting how things bunch up right around and just above 10 years in the organization. The entry for Tony Fernandez in brackets is to show only his first and most substantial stint with the Jays, as others with multiple stints were usually for just a season at the end of their careers and don't affect the order much (if at all).
Major League Service with Blue Jays
For the most part, historical service times (in format yy.ddd) are approximated using game logs, etc.

Ed Sprague and David Wells would be next on the list with just under seven years of Blue Jays service time (about a week or so)
