My question about outfielders is this: why is Garrett Spain on the AAA roster? They picked him up as a minor league free agent, he's not young, he didn't hit well at AA last year, and he can't fill in at infield positions where they are a little thin at the moment. Without him St Paul would still have five qualified outfield candidates*. Wichita meanwhile is short an outfielder, though their schedule doesn't start for another week so other moves could happen.
This whole system seems to be a work in progress.
* I am going by the official rosters listed at the respective milb.com websites, and this data isn't trustworthy, given that they have consistently listed Ryan Kreidler as an outfielder for example.
