Adam Brett Walker

First base | Jacksonville

At 6-foot-5, 225 pounds, Walker's hulking presence is enough to make a train want to jump the tracks rather than risk collision, much less have a pitcher throw the ball anywhere in the strike zone. The Milwaukee native is one of the top power hitters for the 2012 MLB draft. But don't be fooled by his size; Walker is also a perfect 21-of-21 in stolen bases in his career.

2011 stats: .409 avg., 13 HRs, 75 RBIs, 35 walks, 14 stolen bases, 23 doubles

Coach Terry Alexander: "Adam is just scratching the surface of his talent. He is determined to be not only a great college player, but also an exceptional professional player. His power is at a whole different level."
