About the only way I see to "fix" TDAmeritrade that isn't half ass is to lower the field and build the stadium down to it, essentially "moving the fences in" without putting a gap between the fans and the fence. Also may be possible with moving the plate further from the backstop, or some combination of the two.

It's going to be a $5-10mil fix IMO. Not expecting it to be cheap, and if it is, it will be unbecoming of the palace that the park was built as... Probably $2mil+ just in the drainage system under that park...
