I got info on the Corpus roster. It's partial but mostly complete.
P: Nieve, Sampson, Hirsh, McClaskey, Peguero, Mansfield, Kesten, Rijo, and McLemore. There should be at least 1 more joining the team presumably when the Astros make their final cuts.
OF: Anderson, Jimerson, M. Rodriguez, C. Rodriguez. There should be another but I didn't get that info.
IF: Zamora, Eckelman, Santora, Saccomanno
C: Gimenez, Fatheree. Might get another infielder or catcher, not sure.
There are some rumors about guys not advancing as expected. But, that is probably reflected in the big club's uncertainty for the final spots and subsequent reassignments.
