The Astros have signed catcher Kevin Cash to a minor league deal with an invitation to Spring Training, according to MLB.com's Brian McTaggart.
The 32-year-old was once Tim Wakefield's personal catcher, though he spent last season with the Yankees. Cash is a career .186/.248/.287 hitter in close to 600 big league plate appearances, though his minor league numbers are much more respectable. With only two catchers on the 40-man roster (J.R. Towles and Humberto Quintero), all it takes is an injury for Cash to make the Opening Day roster.
