The Indians have just one selection on the first day of the 2011 draft, but it's #8, and given how deep the draft class is this year, they should be getting an excellent prospect.
Gray is 5'11", rather short for a right-handed pitcher, but has excellent raw stuff, starting with a 94 mph fastball with good movement. His slider - which looks like a tight curve - could develop into another major-league strikeout pitch. He also has a changeup, but it's well behind his top two pitches. He has struggled with command, which combined with his size would be the reason he'd be available at pick 8.
Bradley is the second-best left-hander on the board. He doesn't have the upside of Gray, but is probably a better bet to make it into a major-league rotation. He throws four pitches (fastball/slider/surve/change), though none of them are rated plus offerings. He should be able to get the majors very quickly, as he shouldn't need much polishing.
So the choice is as much a philosophical decision as a scouting one. The Indians have shifted their focus in recent drafts and trades towards upside, which is why I'm thinking Gray is who they'll pick if available.
