GeoJSON-Ballparks is my favorite data project I’ve been part of. Probably because not only is it the best sport ever, but it is great keeping track of all the changes at ballparks through the years. MLB teams have mostly stopped building new ball parks so the changes are generally just updates to their names. This year the only new name was Truist Park. Oakland Coliseum reverted back from RingCentral which it never was able to become because of shenanigans. We do bring on a new ballpark in Arlington which is named almost the same as the old ballpark (Globe Life Field vs the old Globe Life Park in Arlington). Apparently the old stadium has been renovated to XFL standards so we should probably not call it a ballpark anymore. I just removed the old one since it is no longer a baseball stadium. I did the same thing with Turner Field.
I plan to review all the Spring Training Facilities of the Cactus League and the Grapefruit League and then review the AAA stadiums. We’ll have to see what happens with the MLB/MiLB negotiations. While it doesn’t affect the actual stadium points (at least in the short term, some of the fields could go away because of lack of support), the alignment of teams in leagues could be changed. So stay tuned and if you want to help out with the AAA stadiums, just create a pull request, would be greatly appreciated!
