John Moores is the majority owner of the Padres. He also has interest in the Astros. But he can't (potentially) buy the Astros until he transfers/sells his majority stake of the Padres to minority owner Jeff Moorad.
When will that happen? Well, they have three years to complete the deal, but Moorad says it won't happen before Opening Day:
"We may very well accelerate it, but we've made no decision on when that will be."
