Any of these prospects worth keeping?

[JASE]

Which prospect has the most upside? Who has the best chance to stick as a regular?

Dustin Nippert SP Ari
Greg Reynolds SP Col
Brandon Morrow SP Sea
Max Scherzer SP Ari

Matthew Antonelli 3B SD
Marcus Sanders 2B SF

[Havok1517]

These guys are the cream of the crop. The Top 3 are pitchers taken in the early 1st round in last years draft, though Scherzer has yet to sign and Antonelli is looking like a Top 5 2B prospect (even though he's playing some 3B). Morrow likely is the safest since he's already on the Mariners. Reynolds was picked 2nd last year and is paying well while Scherzer will likely be redrafted in this years draft, so he's likely the furthest pitcher away.

Brandon Morrow SP Sea
Max Scherzer SP Ari (did not sign)
Matthew Antonelli 3B SD
