RHP Jose Valdez was activated from the 7-day DL.
3B Kyle Redinger was assigned from the GCL to Tri-City.
RHP Richard Rodriguez was assigned from Greeneville to the GCL.
OF Edwin Gomez was signed and assigned to the GCL (Gomez has actually been with the GCL for 6 games now and is hitting .333.)
Another one I missed - The Astros signed RHP Gera Sanchez, a NDFA from New Mexico. It doesn't appear that he has been assigned to a team yet.
