The Strange Opacity of the So-Called Pitching Tools
Recently, I put together a calculator for my own personal use — and perhaps, eventually, the use of this site’s readers — that helps to translate (roughly) a batting prospect’s individual tool grades into wins. Lead prospect analyst Kiley McDaniel already provided something along these lines for Overall Future Value back in September by means of a chart, of which this is an excerpt:
Grade | Role | WAR |
---|---|---|
80 | Top 1-2 | 7.0 |
75 | Top 2-3 | 6.0 |
70 | Top 5 | 5.0 |
65 | All-Star | 4.0 |
60 | Plus | 3.0 |
55 | Above Avg | 2.5 |
50 | Avg Regular | 2.0 |
45 | Platoon/Util | 1.5 |
40 | Bench | 1.0 |
35 | Emergency Call-Up | 0.0 |
30 | Organizational | -1.0 |
Even for those of us unfamiliar with the parlance of scouting, this is fairly intuitive. A player who receives a 50 FV grade is regarded as an average player. An average player, in statistical terms, is one who produces roughly two wins over the course of a full season. It follows, then, that a player who receives a 50 FV is one we might reasonably expect to produce about 2.0 WAR in a season at the height of his talents. Players who receive better grades than a 50 are likely, by some order of magnitude, to produce more than 2.0 WAR; worse grades than a 50, less than 2.0 WAR.
