The Rule 4 draft is almost upon us, and I've updated my ranking of the top 100 prospects in advance of Thursday night's proceedings. (For the previous version of my draft prospect rankings, click here.)

This is not a projection or mock draft -- my latest mock is here -- but a ranking by talent and upside based on my own scouting of players (live and off video) and conversations with scouts from all over the country.

As with my ranking of the top 100 pro prospects, I use the 20-80 grading scale in these comments to avoid overuse of the terms "average" and "above average" across the 100 player comments. On that scale, a grade of 50 equals major league average, 55 is above average, 60 is plus, 45 is fringy or below average and so on.

Now, on to the rankings.
