The Range & Positioning system is simple: A player gets credit (a "plus" number) if he makes a play that at least one other player at his position missed during the season,
and he loses credit (a "minus" number) if he misses a play that at least one player made. The size of the credit is directly related
to how often players make the play. Each play is looked at individually, and a score is given for each play. Sum up all the plays
for each player at his position and you get his total plus/minus for the season. A total plus/minus score near zero means the player is average.
A score above zero is above average and a negative score is below average.
Range & Positioning is only one element of our Defensive Runs Saved system. Here's an overview of the eight methodologies that comprise
Defensive Runs Saved:
1) Range & Positioning Runs Saved – measures range
2) OF Arm Runs Saved – measure outfielder arms
3) GDP Runs Saved – measures double play ability
4) Bunt Runs Saved – measures ability to field bunts
5) Good Plays and Misplays Runs Saved – measures
contributions on miscellaneous plays which prevented or
allowed a batter or baserunner advancement
6) Catcher Stolen Base Runs Saved – measures the
catcher’s ability to control the running game
7) Pitcher Stolen Base Runs Saved – measures the
pitcher’s ability to control the running game
8) Adjusted Earned Runs Saved – measures the
catcher’s handling of pitchers
