In baseball, when a forfeit occurs, the score is 9-0. Why 9-0? What does this score mean, and what is the historical reason for this value?
Wikipedia says, "In the event of forfeiture, the score is recorded as "9 to 0", as per rule 2.00 of the Major League Baseball Rules Book."
The major league rules (page 16) state, "A FORFEITED GAME is a game declared ended by the umpire-in-chief in favor of the offended team by the score of 9 to 0, for violation of the rules."
As for the number 9 - it seems to relate to the number of scheduled innings played out in a professional standard 9 inning game. For softball and little league, for example, the score would be 7-0 since those games schedule only 7 innings of play. I also found something that said that in the event that the forfeiting team is trailing in the score, the score will remain as-is. So, if the team that had to forfeit was behind, say 5-1 - the final score would be recorded as 5-1. I believe the "9-0" score is the rule for games that are forfeited and never begin playing out or where the score is tied.
Yes. The offended team wins each inning of play by the minimum number of runs required to win that inning which is 1 run.
