9am for practice facilities
9am to noon on game days. 9am to 1pm on non game days
The cages are part of the practice facilities that surround the ballpark. These are separate entrances, but highly accessable to the public. One of my favorite parts of spring training is the high level of interaction with the players and coaches, and the practice fields are the best place for that. They open early, i believe by 9am and are free. Enjoy!
I think the gates open at 11:30.. but not sure about the cages.
