Have the Astros signed Brady Aiken yet?

The deadline? to let the Commissioner's office know that teams have signed their draft picks WAS at 7/18/2014 4pm Central. Here is a running update of updates.

UPDATE: UMMM, so this is interesting.

The expectation from those close to the negotiation is that Brady Aiken will end up making a deal with the Astros around the Nix hearing.
