Thje reason Smoak is hitting fifth is because they started the year with him hitting 4th, and he was being too aggressive...so they moved him down to take pressure off of him and that accomplished two things:
1) He started tearing the cover off the ball
2) Olivo had protection and got a few pitches to hit and started hitting for power a bit more consistently.
Olivo is no great shakes, and he's not hitting THIS week, but he has been continuing to get pitches to hit and driving fly balls to the outfield...some of which will be home runs anywhere but Safeco, and you can't move Smoak back to 4th until you're sure he won't start pressing again.
