The following is the Bill James Value Approximation Method for determining the values of players. This is meant to be a tool that is used to help evaluate players in the B-Nut Leagues. It is not, however, the definitive answer to which player may be the most valuable. That decision rests with the commissioner of each league as there are usually additional factors that the numbers may not reveal.

Non-pitchers:

1. Award 1 point if the player has played at least 10 games, 2 if 50 games, 3 if 100 games, 4 if 130 games or more.
2. Award 1 point if the player has a batting average of .250 or better, 2 if .275, 3 if .300, . . . 7 if .400 or better.
3. Award 1 point if the player's slugging percentage is above .300, 2 if above .400, . . . 6 if above .800.
4. Award 1 point if the player has a home run percentage (home runs times 100 divided by at-bats) of 2.5 or more, 2 if 5.0 or more, 3 if 7.5 or more, 4 if 10.0 or more.
5. Award 1 point if the player walks one time for each 10 official at-bats, 2 if twice for each 10 at-bats, 3 if three times for each ten at-bats. (Walks divided by (at bats divided by 10))
6. Award 1 point if the player steals 20 bases, 2 if 50 bases, 3 if 80 bases.
7. Award 1 point if the player drives in 70 runs while slugging less than .500, or 1 point if he drives in 130 while slugging less than .600.
8. Award one point if the player's primary defensive position (the position at which he plays the most games) is second base, third base, or center field, 2 if it is shortstop. For catchers, award 1 point if the player catches 10 games, 2 if he catches 80, 3 if he catches 150.
9. Award 1 point if the player's range factor is above the league average at his position. Catchers and first basemen have no range factors; first basemen get 1 point if they have 100 assists.
10. Award 1 point if the player's fielding average is above the league average at his position.
11. Award 1 point to a shortstop or second baseman who participates in 90 or more double plays, 2 for 120 or more, 3 for 150 or more. Award 1 point to an outfielder who has 12 or more assists plus double plays. Award 1 to a catcher who is better than the league average in opposition stolen bases per game.
12. Award 1 point if the player has 200 hits. Award 1 point if the player leads the league in RBI (runs batted in).
13. Reduce all points awarded on rules one through twelve for players who have fewer than 500 at-bats and fewer than 550 plate appearances. Reduce by at-bats divided by 500 or plate appearances divided by 550, whichever is better for the player. Sum up the points.

Pitchers:

1. Award 1 point if the pitcher has pitched in 30 or more games, 2 if 55 or more, 3 if 80 or more.
2. Award 1 point if the pitcher has pitched 40 innings, 2 if 90 innings, 3 if 140 innings, . . . 7 if 340 innings.
3. Figure for the pitcher his total of 2 x (wins + saves) - losses. Award 1 point if the pitcher's total is 6 or more, 2 if 14 or more, 3 if 24 or more, 4 if 36 or more, 5 if 50 or more, 6 if 66 or more, and 7 if 84 or more.
4. Award 1 point if the pitcher has won 18 or more games. Award 1 point if the pitcher led the league in saves.
5. Establish a mark 1.00 run above the league ERA (earned run average). Subtract the pitcher's ERA from this, and multiply that by the number of decisions that the pitcher has had (W+L+S). Divide by 13. (What you are doing here is giving credit for a low ERA.) If the pitcher's ERA is more than a run above the league average, this will result in a negative figure, a subtraction. A pitcher's approximate value can be reduced by this factor, but no player's approximate value can be reduced below zero. Sum up the points.
