Just caught this article by Purdy today. http://bit.ly/14h826Q.
Kinda lines up with all the other posts on the subject as well.
The article basically confirms that SJ has a antitrust claim against Giants/MLB for blocking a proposed move. Of course everyone knows that but the big news is that SJ has now quantified the damage in $'s. But I would suppose that SJ cannot move forward without the A's initiating or joining the suit.
