Cape Cod has significant convenience from a travel point of view. A scout can travel to any game within a short time if centrally located. The league may need to stagger game times to allow a scout to see more players in a single day, but that seems like something they should have already been doing. The fields have data to track pitches and I assume some hitting data. Playing surfaces are solid high school quality but some parks are smaller than desired. The quality of Appy league fields are not that great overall and the travel seems less than convenient for all involved.
How much of the propping up of former minor league fields / league circuits is a political band aid by MLB that is going to be ripped off in two to three years. Granted if MLB tells players to go to specific leagues then they will probably listen if it gets them the looks they need. It will be interesting to see how it works out.
Hopefully, it is a working solution for all that have lost minor league baseball.
