Probably depends on your definition of the numbers. I found this on baseball examiner. Baseball prospectus and america both have similar rankings but you need a subscription, I believe. #1 Starter: Two plus pitches, average third pitch, plus-plus command, plus makeup #2 Starter: Two plus pitches, average third pitch, average command, average makeup #3 Starter: One plus pitch, two average pitches, average command, average makeup #4 & #5 starters: Average velocity, consistent breaking ball, decent changeup, command of two of the pitches. A plus is a 60 or better, avg is 50, plus plus is 70. Makeup is focus, intensity, etc. All three guys - Appel, Zimmer and Gausman - could become #1 pitchers. I think the knock on them all has been it's not as likely to happen for them as it was for, say, Verlander. Gibson, I think, has one plus pitch and a couple close to plus (55s) so we'll see. He could be a #2 or #3. Keep in mind, before he was hurt, he was likely to go in the top 10 of a pretty solid draft. I have no idea on Wimmers. His change up is supposed to be plus but he's command and now his injury ...
