I don't think it likely that all of Braun, Davis and Gomez make it through a full year without injury. They will all miss time and need regular time off. All are right handed so a good backup left handed hitter will probably receive about 400 PA. That's almost a full time player. If we were talking about a full time player and not considering defense, you may be right. We are not. We are talking about a backup who will most likely make most his starts against RHP. Looking at splits just against RHP they are both really similar. Parra actually comes out a little ahead because of his far superior power. Interestingly Parra has a better BA against RHP and I know how much you love BA. Taking defense into account Parra is the far superior option. Parra had better results. Anything beyond that, in my opinion, is just trying to rationalize a personal position. Bottom line Parra is currently the better player who is in the middle of his prime years while Aoki is an aging lesser player.
