I'm in a 20 team fantasy league Which guys do you feel have the youth and ability to develop into top prospects?

I'm thinking of guys like Elvis Andrus or Jose Tabata, young guys who have shown tools and abilities well beyond their years, but are still some time away from making a significant impact.

Some other guys I've taken notice of are

Pablo Sandoval, Giants - 18, .330/.383/.425 in Northwest league

Angel Salome, Brewers - 18 .415/.469/.673 in Pioneer League

Any other names you can throw out there?

Thanks
