Honestly, I can't think of another reason. He should be batting third, Huff 4th, Burrell 5, Guillen 6...

but the problem then is that whether you stick Pablo or Uribe in the 8 hole, they're not going to get great pitches to hit with the pitcher on deck, and they have a tendency to expand the zone too much. The flip side of that is that they're going to be aggressive, which is what you want out of the 8th place hitter when you've got runners on.
