Geoff Blum has reached an agreement to join the Astros' television broadcast team as a color analyst. This effectively means that he's retired from baseball. Blum was limited to just 17 games during the 2012 season due to an oblique injury. The 39-year-old infielder played with six teams during his 14-year MLB career, including two stints with the Astros. He'll call 60 games in 2013.
