Roster Moves - 1/17/12

The Astros signed OF Jack Cust to a one-year deal with an option for a second year.  Here is the story.

A corresponding move will have to be made on the 40-Man Roster.  Unless other moves are forthcoming, I think Arcenio Leon may be the odd man out, but that's just a guess.

UPDATED TO ADD:
Craig Bjornson has been hired by the Astros to be Bullpen Coach.  He had been a minor league pitching coach for the Rockies organization.
