Scorekeepers

• During a game, a crew of three people work behind the scoreboard to change all the scores from other American League games. Electronic scoreboards display ongoing scores from National League games.
  
  

Size

• The scoreboard has a total of 127 slots. The hit and run numbers are 16 inches by 16 inches, while the innings, errors and pitcher's numbers are 12 inches by 16 inches.
  
  

Changes

• As Major League Baseball has expanded the number of teams, the manual scoreboard has stayed the same size. Fenway Park's first electronic scoreboard was installed in 1975, when the wall was remodeled.
  
  

Autographs

• Red Sox players have made it a tradition to leave their autograph on the walls inside the room behind the scoreboard.
  
  

Tribute

• The initials of former owners Tom and Jean Yawkey are in vertical stripes of Morse code on the outside of the scoreboard.
