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. |
