The 25-Man roster is full. The 40-Man roster is at 39, with Thatcher's DFA. The Astros have Kazmir on the way, and Lowrie rehabbing in Corpus for a return sometime next week (personal speculation only). So that's two spots on the active roster that will need to be filled...what will the Astros do with them?
The Astros will need to clear one spot on the 25-Man in the next 24 hours. Here are the possibilities I can think of:
a) Send Singleton back to Fresno. Lowrie will be getting time at the corners when he returns, and there's always Gattis and Carter getting time there, as well.
