I just don't think there's really a position for him and the standard line up doesn't really lend itself to needing a lot of pinch hit opportunities. While he's gotten a handful of opportunities at 3B, I haven't heard anything that says he's close to handling the position. Carrying two essentially first base only players, especially with the four outfielders using the DH position as half days off, just doesn't seem feasible. If you dump Berti you don't have a middle infield back up, if you dump Brujan you don't have an outfield back up beyond blowing the DH. So then you're left with cutting Turner, and while I think it's a possibility for an established bat, I don't think Long is the guy they're going to do it for. Trading out Turner, who has been very bad for a rookie to get very sporadic ABs given what we've seen from an adjustment period, doesn't seem like much of an upgrade, and that's ignoring the soft skills of Turner (value those as you wish).
