Help with my prospect roster?

[KoolPapaBell]

I'm looking to shed some of the dead weight on my 8-man prospect roster (for a 5*5 roto league). Here is how I currently have my 8 guys ranked:

1) Brett Lawrie
2) Matt Moore
3) J. Segura
4) N. Castellanos
5) T. Wheeler
6) R. Delgado
7) J. Odorizzi
8) G. Green

I think I should cut a pitcher (maybe more than one?), and probably Grant Green at this point. I know some names from the off-season, but I don't have my finger on the pulse of the up-and-comers.

It's a relatively shallow league, so higher ceilings are more important to me than high floors.

Some pitchers available:

Dellin Betances
Zach Lee
Tyler Skaggs
Matt Harvey
Jarred Cosart
Arodys Vizcaino
Garret Richards

Some position guys:

Aaron Hicks
Chris Carter
Billy Hamilton
Josh Sale
Schoop
Gyorko
Marisnick
Szczur

All input welcome; thanks in advance

I think Vizcaino is your man for a high-ceiling pitcher.

Curious as to why you are so down on Odorizzi. He was a pretty legit Top 50 type prospect heading into the season and he has only gotten better. He should see AA by the end of the year and at worst likely start in AAA next season with an eye on a mid-season call-up.
