Harrison has shown a great deal of adjustment as he's gone up the organizational ladder, which we've seen him become a strong on-base guy. Reynolds, at 23 in AA, had an OBP close to .400. Right now, Reynolds looks like Walker's ceiling, not floor. His floor is AA. It doesn't really matter if other prospects led their league in HR or slg or whatever. Those starts aren't predictive. Several players have done that without sniffing the majors - Tim Wheeler, Vinnie Catricala, Nate Gold, Hunter Morris etc. Walker's problem is that he has shown no plate discipline and it has gotten worse as he's gone up levels. Hopefully, it improves because he doesn't need to get on-base much to be a solid player at the ML level. But he can't be a sub-.300 OBP guy in AA and expect to be a ML prospect.
