Tyler Sample, RHP: This 6-foot-7 power arm has a ceiling that might rank with that of anyone in the system. 13. Derrick Robinson, CF: Scouts still love his tools, especially the 80-grade speed, but 2010 could be a make-or-break year for him. 14. Carlos Rosa, RHP: The strong-armed Dominican has tons of velocity, but it's more than bit straight. 15. Kila Ka'aihue, 1B: The minor-league TTO hero failed to build on his 2008 breakout, and now just seems like a walks machine.
