Who says there's no natural selection in baseball? Within the Chronicle's G46 recap, Kaz Matsui was placed on the DL with a strained right hamstring.
And with that, Matt Kata is now your IF5, his contract being purchased from Round Rock. I imagine this is because the Astros will need someone to share some starts with Keppinger. Maysonet is locked in at 2nd for the time being.
