Per Anthony Andro, MLB has released a statement on the Rangers sale:
Major League Baseball is currently in control of the sale process and will use all efforts to achieve a closing with the chosen bidder. Any deviation from or interference with the agreed upon sale process by Mr. Hicks or any other party, or any actions in violation of MLB rules or directives will be dealt with appropriately by the Commissioner."
Reading between the lines, MLB is saying to Tom Hicks, BMFF.
