At this point I don't think they trade Hiura, wouldn't rule out trading Voit. In the end though I believe Hiura makes the team, Voit is added to the 40 man and optioned.
Brosseau makes the team as well as a guy that can hit left hand pitching and be the weak side platoon for Winker/Tellez.
Would probably go with Toro as the final guy for now. Could be out of convenience being a local guy but Miller seems to always be at events promoting the Brewers so maybe he makes the team somehow.
For the guys you listed as on the bubble for pitchers will go with Strzelecki, Guerra, Payamps, Wilson to maintain depth at the start of the year but guys will have to have positive results in order to keep their spot.
