The Leaderboards screen (League Menu >> History section >> Index >> Leaderboards link) is actually a collection of many different leaderboard reports for your league. The first screen that appears is a list of all single-season records for the selected league on the left, and career records on the right. Batting information is listed first, pitching below that.

Across the top of the page are hyperlinks to individual positions. Clicking any of these hyperlinks will display a nearly identical report. The main difference is that the data on the page will now include only players who played the selected positions (for example, the leaderboard for all catchers).

Each report also has hyperlinks in each row, in the column called Board. Each row has a "Season" link on the left and a "Career" link on the right. Each of these hyperlinks will take you to another leaderboard. For example, if you click on the 'Season' hyperlink in the Batting Average row, you will be taken to a report that shows the Single Season Batting Average Leaderboard.

These boards can also be manipulated further by position. So, if you first select Catcher, and then click on the Season hyperlink in the Batting Average row, you will be taken to a report that shows the Single Season Batting Average Leaderboard for catchers.

All of this provides for a vast number of leaderboard reports. All leaderboard reports use only regular season statistics. Playoff statistics are not tracked in the leaderboard reports.

Note: In leaderboard reports, active players are noted with a # sign after the player's name. Players who are in the Hall of Fame are noted with a * after the player's name.
