If I had this staff:
Rotation-- Wada (28/59, pitch counts 80/85)
Pagan (33/88, pitch counts 130/145, pull rating closer to 1 than you'd like because you really need him to pitch 230 innings or more)
Ceda (31/63, pitch counts 80/100)
Goya (26/97, pitch counts 120/130 with a pull rating of 4-ish)
Gil (23/75, pitch counts 85/90)
Your two genuinely good pitchers with the challenging DUR/ST, Dawley (22/56) and Wada (15/68), I would use as SuA with pitch counts of 25/35 or something like that. You'll get 120 or so 7th-9th innings in close games out of each, which I would prefer to the 140 or so 1st-4th innings they would give you as starters, especially since they'll generally have less in-game fatigue. Ramos (one of the short guys) is an SuA; the other two short guys are SuB. The guy you find in Rule 5 to replace German is your mopup. You'll almost certainly need a 12th pitcher.
It can work with the right 12th pitcher.
