There are certain posts that cannot be improved upon and the ones that have been put up here so far are excellent. I happen to agree with justbb in particular - THEM decides everything. Everything is up to them.
Look, I think a baseball dream can be chased only ONCE. The academic thing can be chased at different times of life and still achieve spectacular results. For instance, one could choose a better baseball experience overall yet lower perceived academics in the short term. If the baseball thing does not work out, you can always finish your degree or get an advanced degree at a name school IF that is even necessary. If you forgo baseball on the other hand, you basically cannot rectify that decision in the future.
