In The Most Obvious Move of the Off-season, the Astros have tendered a contract to Jason Castro for 2014, but as Evan Drellich notes, it doesn't mean that they're done talking...
Salary arbitration figures do not have to be exchanged until Jan. 17, and potential arbitration hearings are not scheduled before Feb 1. At any point, the Astros and Castro could agree on the dollars on their own, and the likelihood is they will.
They could even sign him to a long-term contract.
Read the article, and marvel at its wonders. As TCB pointed out this evening, why would you ever continue to read Astros County (and TCB, and...) if the beat writer is going to do basically what we would have done?
