## Batting Career Graph

This uses a player's seven best offensive seasons, determined by offensive Win Shares. For players with less than seven career seasons, all of their seasons are included.

Rate stats are compared to the league averages (which are adjusted for the player's ballpark). For example, a player with a .290 batting average with a league average of .260 would be 11.5% better than league average. This number is then compared to the x players with the most plate appearances (where x = # of teams that year multiplied by 8), to find the percentile. This is done for all seven seasons, with the mean percentile (weighted on plate appearances) being the final value that is displayed on the graph.

For categories that contain three bars:

Left = versus left-handed pitchers

Center = versus all pitchers

Right = versus right-handed pitchers

### Statistics Used

wOBA = Weighted On-Base AverageBA = Batting Average

OBP = On-Base Percentage

SLG = Slugging Percentage

ISO = Isolated Power

HR% = Home Run Percentage

BB% = Walk Percentage

K% = Strikeout Percentage

BB/K = Walks per Strikeout

SB = Stolen Bases per Opportunity

As a general rule of thumb, high percentiles are good and low percentiles are bad. A batter in the 98th percentile of strikeout percentage is better than 98% of the league at avoiding strikeouts.

## Pitching Career Graph

This uses a player's seven best pitching seasons, determined by pitching Win Shares. For players with less than seven career seasons, all of their seasons are included.

Rate stats are compared to the league averages (which are adjusted for the player's ballpark). For example, a player with a 2.50 ERA with a league average of 3.50 would be 40% (3.50 / 2.50) better than league average. This number is then compared to the x players in the league with the most batters faced, to find the percentile. This is done for all seven seasons, with the mean percentile (weighted on batters faced) being the final value that is displayed on the graph.

#### For starting pitchers

1970-Pres, x = 5 * # of teams that year1901-1969, x = 4 * # of teams that year

1890-1900, x = 3 * # of teams that year

1880-1889, x = 2.5 * # of teams that year

1871-1879, x = 1.5 * # of teams that year

#### For relief pitchers

1970-Pres, x = 4 * # of teams that year1950-1969, x = 3 * # of teams that year

1871-1949, relief pitchers are included with starting pitchers

For categories that contain three bars:

Left = versus left-handed batters

Center = versus all batters

Right = versus right-handed batters

### Statistics Used

wOBA = Weighted On-Base AverageR/9 = Runs allowed per 9 innings, with an adjustment for fielders

FIP = Fielding Independent Pitching

WHIP = Walks plus His per Innings Pitched

BA = Batting Average

HR% = Home Run percentage

BB% = Walk percentage

K% = Strikeout percentage

K/BB = Strikeouts per Walk

CG% = Complete Game percentage

BIP% = Balls in Play percentage

GB/FB = Groundouts per Flyout

Hold = Stolen Bases allowed per opportunity

As a general rule of thumb, high percentiles are good and low percentiles are bad. A pitcher in the 87th percentile of walks allowed percentage is better than 87% of the league at avoiding walks.

## Fielding Career Graph

This uses a player's seven best fielding seasons, determined by fielding Win Shares. For players with less than seven career seasons, all of their seasons are included. To qualify for a percentile rating, a player needs at least 200 career games at that position

Using Defensive Regression Analysis, this graph looks at runs saved per 1000 innings and compares this rate to the x players at that position with the most innings (where x = # of teams that season), to find the percentile. This is done for all seven seasons, with the mean percentile (weighted on innings) being the final value that is displayed on the graph.

## Team Profile Graph

This graph compares a team to all teams over an eleven year period. The categories are displayed in percentile rankings. The eleven year period spans from five seasons before to five seasons after the year in question. For example, the 1998 Yankees are compared to all teams from 1993-2003. Batting and Pitching statistics are park adjusted.

### Statistics Used

#### Records

W% = Winning percentagePythag = Pythagorean winning percentage

BaseRuns = Base Runs winning percentage

#### Offense

R/9 = Runs scored per 9 inningsBA = Batting Average

OBP = On Base Percentage

SLG = Slugging Percentage

SB = Stolen Bases per opportunity

#### Pitching

RA/9 = Runs allowed per 9 inningsFIP = Fielding Independent Pitching

WHIP = Walks plus His per Innings Pitched

K% = Strikeout percentage

BB% = Walk percentage

#### Fielding

Field = Runs saved above average (Defensive Regression Analysis)As a general rule of thumb, high percentiles are good and low percentiles are bad. A team whose pitchers are in the 87th percentile of walks allowed percentage is better than 87% of the league at avoiding walks.

This graph compares each season to all seasons from 1876 to present. The categories are displayed in percentile rankings.
