* Many Detailed Statistics are based on play-by-play accounts accumulated by RetroSheet. These totals may be incomplete (3.6% of all plays from 1918 to 1973 are missing or have incomplete accounts, click link for year and team summary) for some players prior to 1974 and even complete seasons may not match the official totals due to errors in both the official totals and the play-by-play accounts. Pre-1954 seasons have a substantial numbers of games missing play-by-play accounts and should be viewed as essentially incomplete.

Player Page Tricks and Tips

Sum any set of rows by clicking anywhere (not red or blue) on the first and last rows of your selection. We will then compute the totals for the player between and including those two seasons.
Default Setting for this feature: Turn On / Turn Off
Summation of season totals only works for the initial case when the table is in year order. On a sorted table the results may get a bit goofy.

HIGHLIGHTING: Adding a range or series of player's career seasons or career game numbers (like '#1972:batting_standard', '#1970-1980-sum:batting_standard', or '#1998,1999,2001,2002,sum:pitching_standard') onto the end of a player page url causes the seasons to the highlighted and summed. After changing address bar, reload the page to see highlighting. This will work even in links e-mailed to others. Note that for tables with multiple pages the first table is the default. If you want to create a sum for a table other than the first one, select the rows and after the summation window appears click on "permanent link" link.
