General Recommendations

The player, team and league statlines are now dramatically different than when the site first launched, so a comprehensive list of the stats would take far longer and would likely be much less useful than previously. So we have implemented a tooltip solution that shows you a description of the statistic when you hold your mouse over the header abbreviation for the stat. You can try it below.

We also have implemented a sorting feature. When the header abbreviation is red (and this is true of all red text), you can click the header to sort by that column. In many cases the table contains partial season (for a traded player) and full-season data. When this is the case, we hide the partial seasons in the sorted results, and provide another tooltip to bring the partial seasons back. Occasionally, there is a select box toggle that allows you to hide or show players who may not have met some minimum qualification, such as 502 PA's for the batting title. This only comes into play when sorting on ratio stats like on-base percentage, but not counting stats like home runs.

The CSV and PRE tooltips provide a means to get comma-separated values suitable for loading into excel, and pre-formatted text that might work better in things like message boards and e-mails.

In some cases, a player's career may span seasons for which a stat like strikeouts or sacrifice flies are not available and seasons for which they are. In those cases we attempt to mark the statistic as shown 162. This means that this career total does not include all seasons the player played and therefore we do not know the exact number.

For the most common stats found in our leaderboards, we denote league-leading stats with bold text and major league leading totals are further marked with italics. For career statistics, all-time leaders are marked with **'s and active leaders with italics.

When a stat is unavailable, its season entry should be blank, rather than zero. This may not always be the case, but it is what we've tried to do.

Each entry contains the leaderboard appearances for the player in a Stat or Award. The entries are the year, the value for this stat, and their rank for statistics, and the year and the award for awards. Leaders are in bold. Rankings among career and active leaderboards are listed as well. The years are linked to the expanded top 10 leaderboard for the league that year. Links are also given to the single-season, career, active, progressive and year-by-year leaders for this stat (s c a p y).

Players must be in the top ten of the category to make the list for a counting stat. For rate stats, see the complicated explanation of the calculation below.

The All-Star column is just years the player was an All-Star; and the Awards column is the year, the league and then the award and if it is a Gold Glove the position.

Descriptions of the Black and Gray Ink Test and the HOF Standards and Monitor test are below.

Here is a run down of the stats that may be unclear.

What are the minimum requirements to lead a Rate Stat?

This is a bit of a dicey proposition, because the standards have changed quite a bit throughout time. Here is how we computed them for the website. Thanks to Bill Deane, Gerry Myerson and Total Baseball for clarifying some of these issues.

Batting Average, OBP, Slugging Percentage, OPS

In seasons where a player could still qualify for a title without the minimum plate appearances, we have printed out the altered entry with an asterik. For instance, in 1995 Mark McGwire didn't have enough PAs to qualify for the league lead in slugging, but when enough hitless at bats were added, so he qualified, his .636 (down from a real value of .685) still managed to place him fifth in the league. The real number is in his batting line and the altered number is in his leaderboard.

Winning Percentage

ERA, BB/9, H/9, SO/9, etc., etc.

Note that team games are the average or expected number of games played in the league that year. So this could mean 162 even if a team only played 160 due to rainouts.

Hall of Fame Stats

These are metrics designed by Bill James to measure how likely a player is to get into the HOF, and not necessarily how good they were. Used with similarity scores, you can get a good idea of the player's chance of getting into the Hall of Fame.

Black-Ink Test

All-Time and Active Leaders

Named so because league-leading numbers are traditionally represented with Boldface type. The definition for the test that being used here was written in Bill James's The Politics of Glory, p. 65-67. The essential point is to measure how often a player led the league in a variety of "important" stats. This method penalizes more recent players, because they have 14-16 teams per league, while the older players had just 8. To get a point you must lead the league in that category.

Note that Hall of Famers have a wide variety of values for the Black Ink Test, and the method is unforgiving of positional differences, but it is a neat little metric.

Gray-Ink Test

All-Time and Active Leaders

Essentially the same as the Black-Ink above, but it counts appearances in the top ten of the league. For each appearance the values are below. As with the Black Ink, this method penalizes more recent players because they have 14-16 teams per league, while the older players had just 8. To get a point you must be in the top 10 in the league in that category.

Hall of Fame Career Standards Test

All-Time and Active Leaders

This test gives a score of 50 for an average Hall of Famer, with 100 as the max (note Babe Ruth is over 100 due to my simplistic addition of his pitching and batting values), though mine are lower due to some difference in positional adjustments that I'll explain below. It is used to measure the overall quality of a player's career as opposed to singular brilliance (peak value).

Also, I require a minimum of 20 points in this metric before the value is displayed for a player. Anything below that is meaningless.

This can be found in James's book on p. 174-176. All values are for career marks, and I've required 1000 at bats or 500 IP for the rate stats to kick in.

Note that this system excludes relievers because there are no set standards for them.

Hall of Fame Monitor

All-Time and Active Leaders

This is another Jamesian creation. It attempts to assess how likely (not how deserving) an active player is to make the Hall of Fame. Using its rough scale, 100 means a good possibility and 130 is a virtual cinch. It isn't hard and fast, but it does a pretty good job. Here are the batting rules.

Also, we require a minimum of 30 points in this metric before the value is displayed for a player.
