No. 1 prospect Shelby Miller, a righthanded pitcher, and No. 2 prospect, third baseman Zack Cox, have been assigned to the High-A Palm Beach club.
The Cardinals are not in a position to confirm the assignment, but it’s expected that Martinez will continue pitching in extended spring training rather than join the full-season rotation in Quad Cities.
All three assignments make sense. Miller moves up a level. Cox gets his first full season ball experience in Palm Beach. Martinez continues his education before moving to Quad Cities this summer. Smart move by the Cardinals, no reason to push Martinez when he is still new to the country.
As far as Quad Cities, I think their rotation will be fine for the time being:
Assigned to the Quad Cities No. 1 roster as RHP Seth Blair, RHP Jordan Swagerty and RHP Trevor Rosenthal.
