His upside is much higher than that. He's got great hand eye coordination and is extremely confident at the plate (think David Ortiz and Derek Jeter, not Jason Bay or Alex Rodriguez). He's a doubles hitter right now but he's probably going to develop power as he gets older. I project him to be a JD Drew without the injuries. .310 100 30 110 10 as his base numbers. Next season, assuming playing time which is not guaranteed, I think he'll go .300 90 25 100 10.
Grady Sizemore will have more value than Jason Bay regardless of draft position
Aramis Ramirez in 155 G will hit over .300 40 HR 110 RBIs
Brian McCann will have more value than Jorge Posada regardless of draft position
