What is the 20-80 Scouting Scale? Definition and Examples

What is the 20-80 Scouting Scale?

The 20-80 scouting scale is the language pro scouts and front offices use to grade individual baseball tools. Each tool — hit, power, run, arm, field for position players, plus fastball, secondaries, command, and delivery for pitchers — gets a number between 20 and 80. Fifty is the league-average MLB regular. Sixty is plus, 70 is plus-plus, 80 is elite (a one-in-a-generation tool). On the other end, 40 is fringe-average, 30 is well below average, and 20 essentially means "this tool will not play in the majors." The scale was popularized by legendary Pirates GM Branch Rickey and refined into its current form by the Dodgers in the 1960s; it is now used by every MLB org, MLB Pipeline, Baseball America, and FanGraphs.

How the Scale Works

The grades correspond to a normal distribution of MLB performance. With 50 as the mean and a standard deviation of 10, each ten-point step is a full standard deviation. Practically, that means roughly 68% of major-league regulars sit between 40 and 60 in a given tool, only about 2.5% reach 70+, and 80 grades are vanishingly rare.

For measurable tools the grade maps to concrete numbers. Run grades on the 60-yard dash or home-to-first time: an 80 runner clocks 6.3 seconds in the 60 (think Trea Turner, Bobby Witt Jr.); a 50 runner is around 6.9. Raw power maps to batting-practice exit velocity and projected home runs: 80 power means 35-plus homers and 115-plus mph max EV (Aaron Judge, Shohei Ohtani). Fastball velocity grades roughly: 80 = 100+ mph, 70 = 96-98, 60 = 94-95, 50 = 92-93, 40 = 90-91. Hit and field tools rely on a scout's eye — bat-to-ball ability, swing decisions, footwork, hands.

Worked Example

Elly De La Cruz's pre-debut Baseball America report graded out roughly: hit 45, power 70, run 80, arm 80, field 55. Translation: a future star with elite raw power and double-plus speed and arm, but a below-average bat-to-ball question that has played out exactly that way in the majors — huge production with high strikeout rates. Compare that to a high-floor profile like Gunnar Henderson: 55 hit, 60 power, 60 run, 60 arm, 60 field — no 70 tool, but five plus tools and zero holes, which is why he was a consensus top-3 prospect.

Why It Matters

Every draft board, trade evaluation, and prospect ranking is built on these grades. A "55 future value" prospect is projected as an above-average regular; a "60 FV" is an All-Star; "70 FV" is a perennial MVP candidate. Front offices use grades to set bonus offers, build minor-league development plans, and structure trades (you don't deal a 60 FV for two 45s). Fantasy and dynasty players use them to identify breakout candidates a year before mainstream coverage catches up.

Limitations and Common Misconceptions

Grades are projections, not measurements. A 60 hit grade on an 18-year-old in the Dominican Summer League is a bet, not a fact, and reasonable scouts disagree by a full grade or more on the same player. Grades are also tool-specific, not value-specific — an 80 arm on a player who can't hit is worth less than a 50 arm on a 60-hit catcher. And present grades differ from future grades; reports usually list both (e.g., "40 / 60 power" means current 40, projected 60 at peak).

In Legends Deck

Every player card in Legends Deck is built on a 20-80 framework under the hood. Hit, power, speed, arm, and glove ratings are derived from Statcast inputs (xwOBA, max EV, sprint speed, OAA, arm strength) then mapped to the scouting scale so collectors can compare cards the same way scouts compare prospects. A card with three 60-grade tools plays — and trades — very differently than one with a single 80 and three 40s.
