I can see Harrison and Crawford both starting the season in the pen, and that would put a serious crunch on the non-option RP'ers like Moran & Hicks and Rule 5 guy Watson.
1, Chapman
2. Whitlock
3. Slaten
4. Weissert
5. Crawford
6. Harrison
7-8. Moran, Watson & Hicks (one has to go or someone to the IL on opening day.)
Sandoval has to start on the IL, too, or else he or Oviedo becomes a pen piece. Both have an option, according to sp.com, but I'm not sure we demote one, unless they look bad in ST'ing.
AAA: Kelly, Sandoval or Oviedo, Sandlin (SPer?) & Samaniego (all on the 40)
