22. Ballpark at Harbor Yard
Sure, we like a nice ocean or bridge to look at when we take in a game, but this is the Coolest Ballparks list, not a prettiest one, so we're giving props to the slightly dystopian backdrop in Bridgeport, which opened in 1998. Yes, that's some crazy factory in the background (we're not sure what they make; we'll pretend it's munitions), and yes that's the Metro North train humming by beyond the right field wall. Hey, you wanted urban ballparks, right?
