I seem to remember from years ago that players tended to progress better in the minors than they did in the Majors. Almost as if their progression would slow to a halt once on a major league team. I think I know the answer, but players who have room to grow we'll progress just fine in the Majors with good coaching and playing time, correct?

I'm asking for

He will continue to develop, so you should have no worries should you decide to bring up him and pitch him regularly.

He's good enough to pitch in the majors and will develop just fine as long as you use him.

Great, thanks

Thomas Del Rosario - Been in the majors since he was 18 y/o. Still developing two years later (though beginning to slow down as he gets closer to reaching his ceiling)

ML coaching probably helped him advance more than MiL coaching IMO.
