Are there other options? Sure, but not much of quality. A trade can be made for a Chris Archer or Michael Pineda. Or, the team could re-sign Hammel since his market is little to nothing at the moment.
Plus, Rule 5 Draft acquisition Caleb Smith will see action in Spring as a starter or long relief. Hopes are high that he can be stretched out to start in the future.
The team has options. The front office made moved to get to this point and should be trusted to keep the team going.
