There's plenty of room for more seats down the right field line, too. Can anyone tell me what that clunky little building on the right field plaza is? Looks like "sky boxes" of some kind? That thing should be gone in a renovation, I hope.
And I don’t believe you can add more seats down the RF line because the indoor cages are below the deck out there and they have roll up doors along the field side for letting in natural air/light. Extending the stands further takes away that feature. If that’s not a deal breaker then yes it can be done and the facility is just fully enclosed in the underbelly of the stadium.
