As far as different squads go, last year players were moved without it mattering (I think) about where they would eventually wind up. It depends on many factors (again, I believe) sore muscles, pulls, where a player needs to fill a spot for the day. For example, at an A's game last year I saw a player play in two games at the same time, hitting in each inning for three innings. Who goes where during split squads are decided that morning, pitchers from different levels on the same team bus. I'm sure that all said, the people who decide what will eventually be, want to see a lower level guy on a higher level. The other factor is that naturally this is all done according to the Brewers spread sheet on their prospect lists, if they have them, or their rosters, who they think is AAA or AA or MLB.
