And it has been confirmed by numerous sources that the Cubs have, indeed, claimed Julio Borbon off waivers - which means that the Astros didn't. How so? Because the Astros had a worse record than the Cubs in 2012, they had first dibs on him.
I'm trying to think of a reason why the Astros didn't claim Borbon. Would you look and think that Fernando Martinez was a better outfield option than Borbon? Rick Ankiel? He also is cheap, making league minimum. I don't get it, but chalk it up to the Astros' front office doing what they want.
