My guess is they'll target a college arm.
The college bats for that level will almost certainly be gone. Dustin Ackley and Grant Green both should go before #9.
I'd guess the top HS bat, Donovan Tate, will also be off the board.
There should be guys like Vanderbilt's Mike Minor, Baylor's Kendal Volz, Arizona's Jason Stoffel, and Arizona State's Mike Leake. I'm not sure I'd gamble on a HS arm there
