Walker Martin

An excellent athlete who also played quarterback for his high school in Colorado, Martin received $3 million (almost double slot value) after the Giants selected him with the 52nd overall pick last year. He has average or better tools across the board with a chance to develop into a middle-of-the-order hitter. At 6-foot-2, 188 pounds, the lefty-hitting Martin has a very projectable frame, and he should be able to add 15-20 pounds of muscle without compromising his athleticism. He turns 20 in February, so he is quite old for his class, which matters on a lot of teams' statistical models and also makes his statistical exploits (20 home runs last spring) slightly less impressive. Martin is a shortstop by trade and has posted above-average run times, but the expectation is he will move to third base as he fills out. Given his age and the fact he didn't face great competition in high school and didn't play professionally last year after signing, there's extreme risk with Martin to go with a high ceiling.
