Astros signed RHP Jose Valdez to a minor league contract.
He was also added to Houston’s 40-man roster. Valdez, 26, was 3-2 with a 3.43 ERA in 43 relief appearances between Double-A Trenton and Triple-A Scranton/Wilkes Barre in the Yankees organization in 2009. Though he has pitched in the minor leagues for parts of seven seasons, 2009 was his first at the Triple-A level.
