A lot of times, you’ll see us write that a player is young or old for the league. To give a better understanding of just what we’re talking about, here’s a look at the median ages for each full-season league based on Opening Day rosters. What’s notable is that several leagues, most notably the International and Pacific Coast League, have gotten older this year. A year ago, the median age of both the Triple-A leagues was 26. This year, the leagues have ticked up a bit, with the International League’s median age now on the other side of 27. The three Double-A leagues are also slightly older in 2013.
But maybe the most notable point is just how rare it is to see a significant prospect who is truly old for the league. In singling out a player to represent an old prospect for each league, we limited it to players who made our 2013 Prospect Handbook. It’s notable how few prospects there are who are significantly older than the median age of the league. It’s another reminder that even in Class A, there are plenty of older organizational players needed to fill out almost every roster.
On the other hand, it’s quite easy to run deep lists of prospects who are significantly younger than the median age of a league. If you want to dig deeper, we have a list of the 10 youngest players in each league at the start of the season. Unlike the top 10 youngest, for this list we included only players who are currently on active rosters.
