| Pts / Points | Points are Win Shares that a player or team has earned. Because of the way the model performs calculations, actual wins earned are roughly 80% of Points |
| RF | Runs For. The number of runs scored by a team In a given season |
| Off Diff | Offensive Difference. The difference between the number of runs scored by a team in a given season and the league average runs scored by teams |
| RA | Runs Against. The number of runs scored against a team in a given season |
| Def Diff | Defensive Difference. The difference between the number of runs scored against a team and the leage average runs scored by teams |
| Off / Offense | Offense. The number of Win Shares (Points) allocated to the team for offense for the season. This is the total of Hitting, Hitting Adjustment and Speed |
| Offensive Win Shares are the sum of hitting Win Shares (Hitting and HA) and base running Win Shares (Speed). | |
| The model allocates the total Win Shares earned by a team (based on the number of games the team has actually won) to the Offense and to the | |
| Defense based on the number of runs the team has scored and yielded during the season. | |
| Hitting | The number of Win Shares allocated to the batters on the team based on the model's calculations for the season |
| HA / Hadj | Hitting Adjustment. Fudge factor difference between the calculated Win Shares (points) generated by the team's hitters and the offensive win shares |
| allocated to the team based on the team's number of wins and the number of runs scored by the team. For example, if the team's batters had good | |
| stats and a high OPS, but that didn't translate into a whole lot of runs scored by the team, then the Hitting Adjustment would be negative for the team. | |
| Conversely, if the team's batters' stats (OPS) wasn't great, but they scored a lot of runs, then the Hitting Adjustment would be positive for the team. | |
| Allocating HA points to batters is based on lineup synergy. The thought being that good hitters make the hitters around them better (pitchers are forced to pitch | |
| to batters before them in the order for fear of facing a good hitter with men on due to walks). Similarly bad hitters make the batters around them worse because | |
| you don't need to give a hitter anything good to hit with a weak hitter coming up behind him. Therefore, we award HA points to good hitters when a lineup over | |
| achieves and we take away HA points from weak hitters when a lineup under achieves. | |
| S / Speed | Win Shares allocated to the team for baserunning. This number is calculated by the model based on stolen bases by the players on the team. |
| Def / Defense | Defense. The number of Win Shares (Points) allocated to the team for defense for the season. This is the total of Pitching plus fielding. |
| The model allocates the total Win Shares earned by a team (based on the number of games the team has actually won) to the Offense and to the | |
| Defense based on the number of runs the team has scored and yielded during the season. | |
| F / Fielding | Win shares allocated to the team for fielding. This is 20% of the Defensive Win Shares |
| Pitching | Win shares allocated to the team for pitching. This is 80% of the Defensive Win Shares. |
| AB | At Bats for a player in a season |
| OBP | On Base Percentage for a player in a season |
| SLG | Slugging Percentage for a player in a season |
| OPS | On Base Percentage + Slugging Percentage |
| Var | Under fielding, the Win Shares added or taken away from a player based on the runs they've saved or given up due to their fielding |
| Note that catchers (4), shortstops (3) and centerfielders (3) are allocated ten Win Shares to start with due to the enhanced skill level required to play their | |
| positions and the degree of difficulty in their positions as opposed the other defensive positions. | |
| IP | Under fielding, the number of innings played by a player in that season at the particular position. |
| Runs | Under fielding, the calculated number of runs that a player has saved (positive number) or yielded (negative number) during the course of the season. |
| Roughly eight runs one way or the other generates a Win Share (positive or negative) | |
| v-Tm | Under fielding. Ignore this number for our calculations. |
| SB | Under Base Running / Speed - the number of bases the player stole during the course of the season. Note that we're only interested in players with game |
| changing speed - the top 10% of base stealers only are considered in the Baserunning / Speed calculations. | |
| IP | Under pitching, the number of innings the pitcher worked during the season, rounded up or down. Note that Innings Pitched factor heavily into Win Shares. |
| Starting pitchers eat up a lot of innings because they have a repertoire of pitches that allows them to go thru the lineup several times in a game. They get | |
| credit for that. Relievers who have a limited repertoire or are placed into cherry-picked situations or who don't have a lot of stamina or whose managers | |
| don't trust them to pitch a lot of innings are not rewarded with many Win shares. | |
| W | Wins. The number of wins the pitcher was awarded. Note that this number is not Win Shares, altho' it is a major factor in the awarding of Win Shares to |
| starting pitchers. Wins are marginally considered in calculating Win Shares for relief pitchers. | |
| L | Losses. The number of losses charged to a pitcher. Note that this number is not used by the model in calculating Win Shares. Starting pitchers are paid to |
| win, if they don't win, it's irrelevant whether they get a no decision or a loss at that point. | |
| ERA | Earned Run Average. Marginally considered in Win Shares calculations for pitchers. Top pitchers will take their foot off the gas if they've got a big lead in a |
| game. Relievers get an unfair advantage because they may come in in the middle of innings, thus lessening the chances of the base runners they put on scoring. | |
| SV | Saves. Relief pitchers who get saves are a different breed than middle relievers - high pressure and a much higher skill level closing out games. Win Shares are |
| awarded based on saves for relief pitchers. |
