Note: Complete player games played data.
Fielding stats are a combination of official records and RetroSheet records. Both are likely to have substantial errors and will not match perfectly.
View Complete Notes on Fielding Data
Leagues historically made no effort to balance team, league, and player fielding stats. Since 1990 or so, computers have made this feasible, but prior to that there are hundreds or thousands of discrepancies each year in games played (even whether a player played a position), putouts, assists, double plays and errors.
  • Pre-1938 SB & CS data for catchers is estimated from catcher assists, games started and opposition stolen bases.
  • From 1938 on SB, CS, Pickoff, & WP data for catchers and pitchers is taken from play-by-play accounts in the retrosheet files. There are several hundred games without pbp from 1938 to 1973 and for those we may not have any data.
  • CG & GS come from the retrosheet data and should be complete and pretty accurate from 1914 on.
  • Innings played (like SB and CS) come from the retrosheet play-by-play data and should be considered mostly complete from 1938 to 1973 and complete from then on.
  • Stats (PO,A,G, etc) for LF-CF-RF positions (since 1914) is taken from play-by-play or box score data as available.
  • Stats (PO,A,G,etc) for C,P,1B,2B,3B,SS,OF positions is taken from the official reported totals and may have been corrected at various times since their publication.
  • For detailed information on which games retrosheet is missing play-by-play from 1938 to 1973, please see their most wanted games list
  • For detailed information on the availability of data on this site by year, see our data coverage page

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.
