I wouldn't worry about replacing Segura yet. He's young, has shown he has the ability to hit, from what I've read seems to understand that he lacks plate discipline, and has had a rough time off the field this year. I'd give him a chance to improve. That said, if the other spots in the lineup are good enough (not necessarily Silver Sluggers in every slot, but at least not black holes), I can live with him being a weak hitter if his defense is great.
