Houston signed RHP Jose Valdez as a minor league free agent. Valdez comes from the Yankee organization. He is a reliever and split time between AA and AAA in 2009.
Houston also added three pitchers to the 40-man roster before today's 11 pm deadline:
Evan Englebrook, RHP
Matt Nevarez, RHP
Henry Villar, RHP
I am surprised that Drew Locke was not added to the roster. Perhaps this speaks to the number of outfielders in the organization.
These moves leave the Astros with 37 players on the 40-man roster.
