His upside is immense. I'd go so far as to say he has the best raw tools in the entire system. The potential is there for 20+ HR and 40+ SB while playing good defense at SS. However, he some major issues. He strikes out too often, doesn't like to take a walk, and routinely makes mental mistakes in the field. CUBZ99 is right. Among those scouts who don't feel like Lake will ever get his approach in line there's a growing sentiment that the Cubs should convert him to the mound. His arm strength grades out at a pure 80 (on the 20-80 scouting scale) and he could potentially be a dominant late inning reliever (or perhaps even a starter). Even those scouts that want him to stay a position player mostly want him to move off SS (mostly due to mental errors)... but where he ends up is an uncertainty even then -- I've seen 3B, 2B, CF, RF, and LF all mentioned. And whether he moves to certain spots might influence whether he decides to bulk up and trade some speed for power. It's fair to say Lake is a bit of a wild card. Aside from the undeniable tools, everything about him is a question mark. I wouldn't expect to see him in Chicago next year though. While he's certainly got the talent to force his way up, he's got more than enough to be working on in the minors.
