Uhhh... Snider IS the best high school hitter in this class. This class was also considered very weak. Maybin was the second best hitter in last years HS class, yet he was considered a MUCH better hitter at the time of his respectful draft. Just because Bruce was the third best HS hitter last year doesn't mean that Snider is actually a better hitter than Bruce.
McCutchen was also considered better than Snider, reasonably better than Snider actually, at the time he was drafted. He performed very well in rookie ball in the GCL, and earned a promotion to A-ball where he hit even better. McCutchen can also play all OF spots and could very well become a CF - he's got great speed and a good arm - which projects his value that much more. The most impressive part of McCutchen's debut was 37:30 BB:K ratio in 210 ABs - he showed very good discipline, and his contact rate was ridiculous at above 85%. That is usually the biggest struggle for HS draftees, and he showed no problems. Plus, he's got a beautiful stroke with ridiculous bat speed, stays on the ball through the zone, and has great power potential, and at 6', it doesn't seem like his speed is going anywhere as he fills out a bit more.
Snider has been awesome. But, like I said, the hype surrounding him out of high school is no where near the hype that surrounded Upton, Maybin, McCutchen, and Bruce. This is a fact, undebateable. This will obviously affect his location on the prospect sheet - I'm not saying it SHOULD, but it will; you're not asking for my opinion. Snider has very good power potential, but he is not exactly athletic (He IS more athletic than Butler, but not by all that much, and that doesn't say much). Whether he can stick at a corner OF spot is questionable, he could very well become a 1B, which would detract from his value. He shows good patience with a BB:K of 30:47 in 192 ABs, but striking out 25% of the time is not impressive. This is typical of high school draftees, but "typical" doesn't get a kid ranked in the top 50. He's shown very good power, but the fact that it's the GCL takes away from that a bit, and the fact that he is facing weaker pitching will also take away from it. Add to the fact that he is a lefty with a slight uppercut swing, slightly above average bat speed, and a tendency to be a deadpull hitter, and it's going to be very tough to put him in the top 50 with just two months to base it off.
