Well the metrics don't look good for Estrada. Declining K rate, rising BB rate. His first two years in Milwaukee were good, true, but I'm not comfortable seeing the trend. Besides, a guy as homer-prone as Estrada will be disastrous in this division, especially with all these on base machines that we will have to face.
At least Sanchez has a worm killer that will limit extra bases and produce more opportunities for a DP.
