Put in Kata in that trade scenario, instead of Spivey, and I'd go for that deal. Kata has trouble with breaking pitches, is starting to hit the wall as scouting reports catch up with him, and the D'backs have plenty of depth behind him at the position in the minors - Tim Olson, Scott Hairston, etc. Brian Giles is worth it and Kendall is none too shabby a pickup either (especially if his knees can be spelled by a quality backup like Moeller or Barajas which he did not have in Pittsburgh).
Spivey has gone through the adjustment periods, has proven he can suceed at this level, and is more flexible potentially position-wise. I don't fault him for not wanting to try the outfield in midseason - IMHO, this is not a Durazo situation as Durazo did have offseason work both in the Mexican Leagues and at spring training in RF before last season whereas Spivey has had none. I don't want to see a repeat of the Tony Womack, 1999 Game 5 of the Divisionals again. Next fall, winter, and spring start giving him reps in RF and see what develops. Now if he wants to start complaining then, well...
Now with the present mix. Brenly, if you're reading this, try a couple games at least with an infield of:
Hillenbrand 1b
Spivey 2b
Cintron ss
Counsell 3b
I'd even give D. Bautista another shot in RF - neither Delucci or McCracken have set the world on fire out there. Looked like Danny was getting his stroke back during rehab in Tucson.
