This chart was published by Business Insider in September 2011, so you’ll want to add about six years to the ages of each ballpark listed below. I’m sure there are also some ballpark changes that I’m not thinking of right off, so keep that in mind as well.
So, is Kaufman Stadium being all morose and moody for its impending 40th?
Well, the 40th was in 2012 (it’s an old chart), so not so much. 😉 The Royals are gearing up to celebrate their 50th season in existence next year, so could make for some interesting promotions!
