Every year since 1998 I've been keeping track of team's "core ages", which I classify as their keeper list plus their 1st or 1st & 2nd 
round picks.  Below is this year's edition, also showing the last 3 years and the 5 and 10 year mark.    

The Pirates still claim the youngest team title, although when you post a league best 98 wins you tend to keep your core around, so it  
is no surprise that their core jumps by a year.  The world series appearance by the Termites was veteran driven, as their core age 
jumped by nearly 2 years, with San Diego claiming the oldest team mark.
