Walk rate and throwing strikes were an asset in the majors....maybe Sanchez is just one of those players that focuses more once in the majors and in turn is way better than in the minors. Sanchez will be a stud starting pitcher in a few years.
Neither will be the 5th starter....as of now Buehrle, Stroman, Dickey, Hutchison, Sanchez....Norris, Nolin, (6th and 7th)...Happ 8th and Estrada 9th as of now.
I still see Happ moving back to the pen if Sanchez can dominate as a starter in Spring Training. Maybe even Norris. I will be irate if both Buehrle and Dickey are still on the team next year....one has to go
