Chases

Every current major league park. The one every ballpark chaser measures themselves against — most take a decade, and the last one is always the hardest to schedule.

Every current park in the American League.

Every current park in the National League.

Every current park in the American League East. Division sweeps are the most achievable chases on the board — the travel is short and the schedule cooperates.

Every current park in the American League Central. Division sweeps are the most achievable chases on the board — the travel is short and the schedule cooperates.

Every current team, anywhere. Because both clubs count in every game you attend, this fills roughly twice as fast as a stadium chase — a good first chase to adopt.

Boston, both New York parks, Philadelphia, Baltimore, Washington. Doable without a car, and the only chase you can finish on Amtrak.

Every current park in California, north to south.

Both Texas parks. A long weekend and four hours of interstate.

Chicago twice, Milwaukee, Detroit, Cleveland, Cincinnati, St. Louis, Kansas City, Minneapolis. The classic summer road trip.

San Francisco and the Athletics' current home. A single weekend.

Dodger Stadium, Angel Stadium, Petco Park.

Every Cactus League spring park, all within an hour of Phoenix. Clubs share complexes, so there are fewer parks than teams — the single most achievable chase on the board, and a determined two weeks in March does it.

Every Grapefruit League park. More spread out than the Cactus League — this one is a proper road trip.

The venues baseball visited once and left: a cornfield in Iowa, London, Tokyo, Mexico City, Rickwood, Williamsport. You cannot plan most of these — you have to be there the year it happens.

Venues that have since been demolished — and only a visit dated while the park was still standing counts. There is no way to start this chase today; you either were there or you weren't.

The two parks still standing from before the First World War. Two items, and both of them matter.

Set foot in 3 parks you'd never visited before, all within the same calendar year. A park counts in the year you first saw it, so you can't pad two seasons with the same trip.

Set foot in 5 parks you'd never visited before, all within the same calendar year. A park counts in the year you first saw it, so you can't pad two seasons with the same trip.

Set foot in 10 parks you'd never visited before, all within the same calendar year. A park counts in the year you first saw it, so you can't pad two seasons with the same trip.

At least one park you'd never been to, every calendar year, consecutively. Your current streak counts here; your longest is on the record either way.
