Inside the MLB Scouting Scale
A quick reminder when youāre looking at these charts: a 50 on the scouting scale is Major League average. That means if a player is graded as a 50 in power, speed, arm strength, or velocity, they project as a big leaguer in that tool. High school and college players are usually not evaluated only on where they are today ā scouts are projecting where their body, strength, mechanics, and skills will be at physical maturity. So when you see a 40 today, that doesnāt mean ābelow average.ā It means this player has the raw ingredients that could grow into a 50+ big-league tool with development. These numbers help scouts translate workouts, game performance, and measurables into future professional value ā and thatās exactly how draft boards are built.
