|How Does the Baseball Evaluation System Work?
following parameters and premises have been utilized in the
the Baseball Evaluation System and Stat Geek Baseball.
1. That players with high performance values, player grades, receive an
exponential increase in compensation over the average player.
This is accounted for by grading performance levels to year
maximum and average values for pitchers and batters in six categories.
These category grades are then blended in order to
retrieve an Overall Yearly Player Grade (PEVA) for each
season with a
minimum level established for players who do not reach a threshold
2. For position players, each position, due to the numbers
established for their Field Value (FV), has differing maximums and
minimums. This accounts for the fact that players at various positions
on the field are valued differently per offensive and defensive
prowess. For example, ... a catcher has a higher premium on
defense than any other position on the field and will be afforded a
contract at a level higher than other positions with the
same offensive capabilities. Each position, however, can
the Maximum Level (64/32) if their offensive capacity outpaces their
defensive ability. The maximum number for all positions,
including pitching, is 64, although any player who reaches a level of
32 is considered a MAXIMUM player with the number 32 used for salary
3. Of the six categories for pitching or position players, one-third
are Opportunity Categories (i.e. player time). These two
categories form the basis for the other four categories, the underlying
girth that is built by use. If a player is used, he has
His ability and performance in that use fleshes out his
4. Both pitchers and position players have one Category that
considered defensive in nature. Field Value provides that
for a position player. Home Runs Allowed per 9 Innings
and Strikeout to Walk Ratio provide that value for a pitcher.
These two factors, when combined, reflect a defensive
for a pitcher since its basis does not predominantly depend on the
capability of anyone else on the field except the pitcher.
5. Salary Projections (SPRO), see Stat
Geek Baseball, are calculated using a Rolling
Average of PEVA values (RAVE), its correlation with Major
League Service Time (MLST) or the Experience Equivalent (EXPEQ), and
comparison to the current minimum salary and maximum current salary.
PEVA and RAVE values have taken into account injuries that occurred
during those seasons, but they do not attempt to evaluate the status of
individual players as to their current health and value in upcoming
seasons. This creates a deviation when comparing actual
salaries. Actual baseball salaries often do not weight, in
opinion, past durability in a high enough manner. This may be
the largest difference between PEVA, RAVE, and SPRO values in the
Baseball Evaluation system and actual baseball salaries.
we did not attempt to modify this difference, as we firmly believe that
durability is a prime consideration in value and is often later proved
accurate, and that it should have been given greater weight as the
contract plays out.
7. Salary projections also do not take into account a
team’s intention to change the use of a player in future
years, thus decreasing or increasing his value. (For example, changing
the player from a starter to a role player or visa versa.
Field Value Methodology
most controversial factor within the Baseball Evaluation System for
position players is Field Value (FV), which denotes the value of
Fielding for each player who has performed on the playing surface for a
minimum number of innings, currently 162 innings per position (1 per
played), or a total of 162 innings at multiple positions.
The Field Value player grade factor does not absolutely indicate the best fielder at
any given position, although for players with a similar
number of Innings Played, it can perform that function. Field Value was
calculated in order to give the better fielder, whose performance on
the field, as well as his availability and actual use in the field,
indicated value to a team.
For example, ... a great fielder who played
few innings at
the position would suffer in their Field Value, no matter the reason he
was not on the defensive field (offensive woes, injury, etc.). The
being that since he played fewer defensive innings, his value to the
would have been lower. A poor fielder who plays many innings in the
field benefits in his Field Value from the amount of innings played,
having value in the field, even though he may not be the better fielder
than someone ranked lower. It is also possible that a good fielder who
plays for a team whose pitching prevents plays for a particular fielder
could suffer due to that factor. However, this also indicates the lack
of need for that particular team at that position and thus lowers his
value. Although the greatest value would be achieved for a
fielder with a great amount of innings over one with limited defensive
time, it is
still possible for a defensive specialist, who has played at least the
minimum number of innings or games, to be ranked well. While
their component for Innings or Games Played may be low, if that
player is a great fielder, the factors for sure-handedness (Fielding
Percentage), range (Range Factor), arm strength (Caught Stealing
Percentage for catchers and Assists per 9 Innings Played for
outfielders) will significantly enhance their Field Value player grade.
This can also be true for a
limited range, but good hands. Although the Range Factor (Put Outs +
Assists per 9 Innings Played) contributes between 25% and 33% of each
a player with sure hands and a significantly high number of Innings
Played can yield an above average Field Value Factor.
A common question about the value of Fielding per contractual
obligations stems around a highly productive offensive player with few
defensive skills. The relevance of Field Value for a great offensive
player whose bat is so good no team cares about his fielding when
awarding a contract is a valid concern. The Field Value is modified by
other Offensive Numbers in the total PEVA Player Grade to indicate a truer
picture of their value as a total player. Therefore, a great
offensive player will not be punished by a low Field Value, but a great
defensive player will be rewarded.
