Is There a Run Rule in MLB?

is there a mercy rule in mlb

First of all, it’s important to state that there are several names for this “Run Rule”, which is also known as:

  • check
    Mercy Rule
  • check
    Skunk Rule
  • check
    Knockout Rule
  • check
    Slaughter Rule
  • check
    10 Run Rule

However, we’ll call it the Mercy Rule because that’s a name I can connect my feeling as the losing team when this rule happens.

It’s called the mercy rule because it basically spares the losing team from anymore embarrassment. But why would they be embarrassed you ask? This rule is when a game is abruptly ended before the whole game is supposed to be over. This is applied in most sports when there has been a huge difference in score between the winning and losing team, and it has been deemed that it would be impossible for the losing team to catch up by the supposed end of the game.

Major League Baseball and the Mercy Rule

There is no mercy rule in MLB, not even the usual 10 run rule! But there are mercy rules in minor league baseball, and you can count on a mercy rule in high school baseball. I would think the reason for this is that baseball teams in the Major Leagues are the guys that pretty much have a certain level range and it might not be so common. But an MLB Mercy Rule could also cause many issues, here’s an interesting Major League Baseball article talking about the possibility of a Mercy Rule making a negative effect on a game.
