Ranking the Top Prospects in Major League Baseball
by Ryan S. Kelley
Description of Rankings and Scoring Methods:
Below is a rankings database constructed by Ryan Kelley, Executive Editor of Baseball News Hound L.L.C. Top prospects are ranked based on scouting grades derived from Baseball News Hound scouting reports. A list of other sources where information was consulted or used is available at the bottom of this page and listed under "Bibliography."
All scouting grades are based on the standard "20-80" scouting scale. Ratings of 50 and 55 are considered low-average and high-average tools respectively. Low-average and high-average tools are given to prospect skills that project to fall within the range of MLB average when (and if) they play in the Major Leagues. Scores above this range (60-80) are considered above-average, "plus," and "plus-plus" respectively, and indicate skills that project to outperform the average Major League player of the same position. A plus (rated 60-65) fastball, for instance, would indicate a fastball that features consistent 92-95 mph velocity, and movement at or above the average Major League fastball movement. Outside of velocity and movement, a pitches's overall effectiveness determines its' score.
Tools projected to be below average tools are scored in the 20-45 range. Generally however, and tools rated below 40 are extremely rare at the Major League Level. Adam Dunn/Sean Casey running speed are "30" tools, and Jason Tyner batting power would be at the bottom of the scale as well.
All grades account for a players' present and projected ability. Young prospects for instance, won't have the present skills that Major League players and more experienced prospects have, but their potential skills might allow them to grade comparably.
An in-depth description of the scale is available here at Baseball Prospectus.

Top 200 MLB Prospects 2011
Key/Glossary:
The above columns/categories are as follows:
Rank: The players' overall rank in comparison to other top prospects.
Grade: A rough letter grade on the scale F-A+ defining the prospects' overall value. This grade takes in to account their skills, experience level, and any attribute that possibly affects their future. A top-tier, five-tool scout may still fall below the A range due to injury concerns, make-up issues or other negative attributes that could decrease the players' overall value.
D.O.B.: "Date-Of-Birth" is the players' birth date.
Hght/Wght: The players' height (in inches) and weight (in pounds).
OPS: (Batters) Aggregate (Minor League) career On-Base-Plus-Slugging Percentage (expressed as a decimal here)
ERA: (Pitchers) Aggregate (Minor League) career Earned-Run-Average.
Bat: (Batters) A score for the batters' hitting ability. Distinct from power or plate discipline, this is a measurement of a batters' ability to hit for batting average and to make square contact to all fields.
Fb: (Pitchers) A score for the pitchers' fastball effectiveness. The score is based on fastball velocity, movement and the pitchers' ability to utilize it.
Pwr: (Batters) A score for the batters' ability to hit the baseball with authority and generate extra base hits. The score is based on the batters' bat speed, strength, loft and both raw and projected power.
Bb: (Pitchers) A score for the pitchers' "breaking-ball" or repertoire of breaking pitches. The score accounts the velocity, the amount of break, the sharpness of the break and the overall effectiveness of the pitchers' breaking pitches.
Spd: (Batters) A score for a baserunner's in game runnings speed. This score rates a players' running speed on the basepaths, out of the batters box and in the field (while playing defense).
Ch: (Pitchers) A score for a pitchers' changeup(s). The score is based on the pitches' velocity, movement, on the arm-speed with which the pitcher delivers it.
Fld: (Batters) A score for a batters' overall defensive ability. Arm strength, throw accuracy, range, agility/body control are the primary factors taken in to account for this grade.
Cmd: (Pitchers) A scouting score for the pitchers' ability to locate his pitches.
Dis: (Batters) A grade for the batters' plate discipline. The batters' ability to reach base against advanced pitching, to work the count to his favor and to make quick adjustments when needed.
Pol: (Pitchers) A score for a pitchers' effectiveness outside of a pure 'stuff' level. Pitching intelligence, poise/mound presence and clean mechanics are considered here.
