Nelson was hitting 97 on occasion yesterday and working consistently at 94-95. His ceiling is pretty similar to Peralta's, at least a #2 with an outside shot at #1. Nelson's upside is quite high. Nelson is 25. He's very close to his ceiling already. I highly doubt he ever have the command to be an ace, he just isn't naturally coordinated. I like him, but he is what he is, which is likely Aaron Harang. That's impressive, but it's not David Price.
