Not necessarily. I think everyone would agree that different hitters are going to be able to sustain a higher babip, due to how hard they hit the ball, and hitting more line drives. Conversely, some pitchers should be able to sustain a lower babip, if they have movement or deception that gives up less hard contact, and/or less line drives. The key is comparing each player to themselves. (for the most part, some outliers are not sustainable by anyone. ) When a pitcher suddenly sees a 50 point drop in babip one year, compared to his career babip, it's almost certainly luck based. And,.227 isn't sustainable by any pitcher. Greg Maddux had a career babip of .281. Pedro Martinez, .279. Tell me a pitcher that you think limited hard contact the best, and I'll bet his career babip is in that same range.
