One more note. I may be wrong, but it appears that Bruce Chen's emergence in the rotation has had a major benefit for Ervin Santana. I believe Santana has followed Chen in the rotation since the ASB (4 starts).
In those 4 starts, Santana is 4-0 with an ERA of 1.27, 22K/7BB, and a WHIP of 0.882.
I wonder if the change of speed coming off Chen is helping Santana.
