Retrosheet’s bevent program takes a Retrosheet event file and creates a complete description of every at-bat that occurred during the game.  To complete the introduction of Retrosheet’s three pieces of software, I’ll once again start with the event file for the Colorado Rockies @ Los Angeles Dodgers game on 4/9/2007 as an example. Here is the event file.

Here is a step-by-step guide for using bevent.exe.

  1. Download bevent.exe from Retrosheet or here, and unzip the executable file.
  2. Put the event file (or a text file that includes many event files) in the same directory as the bevent.exe program.
  3. You also need to have a team file included in the same directory.  A team file is text file that lists every team, their league, and their three-letter abbreviation.  The team file must have a filename of TEAMYYYY.  For example, here is TEAM2007.
  4. Open the Windows Command Prompt. (Start -> Run -> CMD)
  5. Navigate to the directory where you stored bevent.exe, the event file, and the team file.
  6. Type the command: bevent -y 2007 -f 0-96 dodgers_rockies040907.evn (or the name of your event file).  “-y 2007” specifies the year of the game.  If you are generating game info for a game from 1960, make sure you use -y 1960. “-f 0-96” specifies which fields I want bevent to return.  The default is 0-6, 8-9, 12-13, 16-17, 26-40, 43-45 ,51, 58-61.  0-96 means all fields.
  7. If you want to output the game info to a text file (I’d recommend saving as a .csv file so it opens nicely in spreadsheet software), use the command bevent -y 2007 -f 0-96 dodgers_rockies040907.evn > dodgers_rockies_040907_gameinfo.csv.

    Alternatives to box, bevent, and bgame can be found at Project Chadwick at They can generate the same as above plus more, including xml output. There are also other utilities included.

  2. Thanks for the info.

    I knew these files were available, but I’ve never personally used them.

    I’ll make a note to try them out, and then I’ll add a post to the site.

    Thanks again!

  3. How would I go about using cwevent to output ALL events for a certain year? (Trying to update my db with 2010 statistics)


  4. Make sure that you have all of your event files in the same directory. Use the same command except type the filename of each team’s event file, separated by a space.

    bevent -y 2010 -f 0-96 2010ANA.EVA 2010ARI.EVN 2010ATL.EVN 2010BAL.EVA 2010BOS.EVA 2010CHA.EVA 2010CHN.EVN 2010CIN.EVN 2010CLE.EVA 2010COL
    .EVN 2010DET.EVA 2010FLO.EVN 2010HOU.EVN 2010KCA.EVA 2010LAN.EVN 2010MIL.EVN 2010MIN.EVA 2010NYA.EVA 2010NYN.EVN 2010OAK.EVA 2010PHI.EVN 2010PIT.EVN 2010SDN.EVN 2010SEA.EVA 2010SFN.EVN 2010SLN.EVN 2010TBA.EVA 2010TEX.EVA 2010TOR.EVA 2010WAS.EVN > 2010events.csv

  5. Wow, thank you for your timely response. That worked like a charm. I appreciate it.

  6. I’m using a Mac to run the commands using chadwick and I keep getting the error message that the team file is not found although I am sure it is in the same directory. Is there an additional command needed when setup for Mac?

  7. I just tried cwevent, and it worked fine.

    cwevent -y 2002 -f 0-96 2002OAK.EVA > Testing.csv;

  8. cwgame worked too.

    cwgame -y 2002 2002OAK.EVA > Testing.csv;
