Did Jorge De La Rosa have too much motion on his pitches and being on the Colorado Rockies limits his movement, thereby better control?

Question:  Did Jorge De La Rosa have too much motion on his pitches and

being on the Colorado Rockies limits his movement there by having better

control?

Why I asked the question:  Every time I saw De La Rosa pitch, he seemed

to have too much movement on his pitches and was unable to throw them

consistently for strikes.  After being trade this spring to Colorado, it seems

that he pitched a lot better.  In Colorado, the ball doesn't break that much

because of the thin air.  I just wanted to compare his stats in Colorado's

thin air and away from it 

Analysis:  Jorge's home and away splits for the 2008 season:

With this small sample, it looks like he pitches better in Colorado.  I

decided to compare his lifetime stats to those games when he pitched at

Coors field over his career:

Again, it looks like he definitely does better at Colorado, vice being away

from it.  The sample set of 17 games pitched is quite small, but Colorado

should definitely give him a chance .  They could try to manipulate their rotation

so he can pitch at home as much as possible.
