the latest is that it will take more time for the two Cali teams to move to the Carolina League. So the Astros might have to have an affiliate in the Cal league for one year before moving to the Carolina league.
It looks like Bakersfield (Rangers) and High Desert (mariners) will be moving to Richmond Va & Fayetteville NC.
Look for the Mariners to get the Red Sox affiliate (Lancaster) and then the Astros get the High Desert franchise. The Rangers will be looking to move to the Carolina League as well, so I don't see them breaking ties with team ownership.
