I do not care if it was girls softball he pitched against. No BB and 71 pitches in 6 inn is impressive. Put him in minors to start season to be a starter. I do not put him back in BP and bounce him from pen to starter. It's a long season but maybe a trade happens. Many teams need starters and Anderson could go.
I know only ST game and it's early in the process for Soriano. Today he looked as good as he can be. Develop players from within starters position players BP pieces. This is not a rebuild team to me. This teams direction has been set build from within first before adding any FA.
