I live in Atlanta and watch a lot of Braves games.
Uggla is a case... honestly, he just looks like he is WAY away from making good contact a lot of the time.
It's in his head... which means he could fix it as early as tonight... or it could carry on all year.
Uggla's second half numbers aren't like other players, for this reason.
It's not like he switches it on after a certain amount of the season has passed.
You have to bench him, do it now, find a replacement.
Don't drop him though.
Consider him the hitting-equivalent of RA Dickey.
Great when he's on.
Bad when he's off.
Don't worry about trying to have him active when he clicks on.
Let him put up a few big games of numbers and then add him back into your starting lineup.
