Torkelson has a better approach and better raw power. There is more risk though, with him not being exposed to nearly the pitching quality Mountcastle has been. They grade out similarly as prospects, basically Torkelson is higher ceiling, higher risk. I don't think you draft at all based on what you have in your system, at least in the first few rounds.
@Luke-OH or anyone else’s thoughts...
Better 1B MLB profile, Mountcastle or Torkelson?
If the advantage is Torkelson, is it enough to draft another 1B?
