Optimistically, there's Det and Gorzo in the short term, and we can hope that among Purke, Meyer, Rosenbaum, perhaps Solis if he avoids surgery, one or two is available in the second half of the year for spot starts and to take over when Stras approaches an innings limit.
Really, this only matters if we are within a few games of the wild card in the second half of the year. Otherwise, cannon fodder like Stammen and Maya can get you by. If it matters, and we don't have anyone emerge, then we trade for an expiring contract.
