I am pretty sure that whoever wins the 5th spot could easily be demoted/cut in May if pitching poorly. I don't think the org feels any great loyalty to any of Deduno, Worley, or Diamond, they just may want more than March to figure out if any of them are worth keeping. (The fact that the Twins made an offer to Santana suggests the org doesn't feel very great about them, certainly.) And in that scenario, if pitching well, Gibson would be the first up. Although I admit, if Santana had taken the last spot, it wouldn't have been quite so easy. Personally, I think Correia would have had a relatively short leash in that scenario, given the expiring contract and bullpen experience (and frankly, his mediocre upside). Honestly, Pelfrey and Hughes should probably have similar short-ish leashes -- for their better upside, they are still gambles who have to prove they have improved. Although their leashes are probably longer than a month or two unless they absolutely fall apart like Worley 2013.
