Santos will get a mulligan for this start as the presumptive "no. 3 starter". But his situation is a lot like Matt Kinney's was last year. He's not so solidly entrenched that he can continue to be rocked and expect to keep a job. Especially this year with so many guys fighting for starting jobs. Between Capuano, Capellan, Hendrickson, Helling, Glover, De la Rosa and yes Obermueller, they have enough to fill not just 2 rotation spots, but 3 if Santos struggles.
