Not sure how Steamer purports to be able to predict defense, but in any event I think that is probably projecting him to be slightly below average plus the -7.5 positional adjustment for being a corner outfielder, just to put it in context. I'm not quite sure how or why they would project him to be significantly worse than his career or recent UZR numbers when he is only 28. It could be that they are projecting him to play a little bit of CF for us, based on the percentage of games payed there in the most recent season. I think ZiPS does "dumb" positional projections like that. Though obviously Garcia is behind Cain, Yelich, Gamel, Taylor, and Broxton in our CF depth chart. His offensive numbers should also get a significant boost if nothing else from the Brewers being able to let him accumulate higher portion of PA against LHP, given that not all four of Yelich, Cain, Braun, and Garcia are like to amass 559+ PA.
