There's a 10 pager on Butler on the Leftovers board worth looking at. Looks like it just got bumped to page 2:

The plus is he hits well, but in KC that may not translate to run production, only avg. Right now is his audition for whether he gets PT when Shealy returns. He was hitting .337 in AAA, and thru 5 games with KC he's at .333 after an 0-5 night last night.
With Gordon not producing - like KC in general - there's a decent chance he not only sticks, but gets solid PT, after Shealy's DL stint. Personally, I'm hoping he gets in 4 more games at 1B in the next 10 days, so I can stash him as a Giambi back-up.
