BB% | Walk% | Formula: { bb/pa }. How many times a player walks per 100 plate appearances. |

BB/K | Walks per strikeout | Formula: { bb/so }. A ratio that compares the number of walks to strikeouts for a batter with the intention to see if a player has more positive non-contact at bats compared to negative. |

BrOuts | Baserunning Outs | Thrown out on basepaths by trying for an extra base or for other reason. Does not include being forced-out at a base or caught stealings. |

Whereas batting average ignores walks and hit by pitch as positive batting events, OBP uses all instances of a batter reaching base to provide a different view of a player's effectiveness. An obp of .360 is considered good. |

Complete Formula using A,B,C is { (((2.4c+A)(3c+B))/9c )-.9c. This algorithm is intended to measure the number of runs a player has created in his at bats and is intended to be a better measure of his offensive contribution. |

SLG | Slugging Percentage | Formula: { tb/ab }. A measure of a player's power or their ability to produce bases. Batting average and On Base Percentage count all hits equally while slugging percentage considers hits with more bases earned as more valuable then lesser hits.

GB/FB | Groundball/flyball ratio | Formula: { groundballs/flyballs }. Indicates how many groundballs to flyballs a pitcher allows.

InRV | Inherited Runners Value | The value of inherited runners on base when a relief pitcher enters the game where a runner on 1st has a value of 3, a runner on 2nd has a value of 2 and a runner on 3rd has a value of 1 in an attempt to provide some leeway for relief pitchers entering with a runner on 3b and less than 2 outs whereby allowing the runner to score is not an absolute failure. |

### Fielding Statistics

A | Assists | A fielding play where a ball thrown by the fielder to another fielder results in an out. |

DP | Double Plays | Instances where a player was involved in a play where at least 2 outs were required, most of which occur on groundballs to infielders. |

FPct | Fielding Percentage | Formula: { (PO+A)/(PO+A+E) }. A basic formula that explains the percent of success on fieldable balls. The limitation of fielding percentage is that it does not consider a player's range and therefore a player is not penalized for not being able to get to a ball that most fielders would be able to field. |

RF | Range Factor | Formula: { TC/G }. Considers the amount of balls successfully fielded per game. Does not consider the number of innings and therefore a late-inning replacement will have a low Range Factor will not be representative of his value. More suited to starting fielders. |

RF9 | Range Factor per 9 innings | Formula: { (9/inn)*(PO+A). Determines the number of plays made at a position per 9 innings thus allowing for comparison between fielders of the same position with an equal denominator. The range factor is intended to determine a player's range at a position compared to his peers but there are other factors that might contribute to a high range factor such as opportunity. A team facing more left-handed batters will have more opportunity for the right side of the infield. |

TC | Total Chances | Formula: { PO + A + E }. All possible chances in the field not including balls that a player could not reach. |
