The grievance filed against the Houston Astros after two high draft picks went unsigned last month was filed on behalf of fifth-round pick Jacob Nix, not No. 1 pick Brady Aiken, according to a pair of sources.

There will not be any movement in the grievance until after the regular season.

"Nix will not be resolved before the offseason," a source said. "Nothing has changed since deadline day."

Nix passed a physical and agreed to a $1.5 million signing bonus with the Astros, but the deal was not honored when Aiken went unsigned.
