Actually, if you want an honest knock on Avila, I'd say one of them is his penchant for falling for what I would call 'faux switch hitters" i.e., guys who stand in the LH batters box against RHP but actually have worse platoon splits against RHP than the average RH only hitter. Goodrum, W. Castro, Reyes all examples. When your OPS platoon split is >200 pts, it's unclear why you aren't just hitting from your better side.
