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.

Diamondbacks activated INF Geoff Blum from the 60-day disabled list. Blum batted just .237 (9-for-38) over 12 games during his rehab assignment, but the important part is that he didn't feel any discomfort with his oblique muscle. The Diamondbacks placed John McDonald (back) on the disabled list in a corresponding roster move.

That silly two-year, $2.7 million deal handed to Blum finally paid off for the Diamomdbacks, as he knocked in his third, fourth and fifth runs of the season. He doesn't figure to play a lot behind Ryan Roberts this month, but perhaps that will change if he puts together a hot streak.
