In a six-inning game such as Little League Baseball and Softball, rules call for the game to end if the winning team is ahead by 15 runs after three innings played or 10 runs after four innings played by the trailing team.
A slaughter rule, also well known by the slightly more polite term mercy rule or less commonly, knockout rule, brings a sports event to an early end when one team has a very large and presumably insurmountable lead over the other team. The winning team is said to be “slaughtering” the losing team.
Unless there is a game immediately following, there is no ten run rule except after 7 innings and then only with mutual consent of both coaches as agreed to with the home plate umpire during ground rules prior to the game.
In baseball, an official game (regulation game in the Major League Baseball rulebook) is a game where nine innings have been played, except when the game is scheduled with fewer innings, extra innings are required to determine a winner, or the game must be stopped before nine innings have been played, e.g. due to …
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.
What is the highest-scoring game in MLB history? As noted in the list above, the Cubs and Phillies own the highest-scoring game in MLB history with 49 total runs on Aug. 25, 1922. Philadelphia once trailed 25-6 and almost pulled off an improbable comeback, but fell three runs short of tying the score.
If at the end of a regulation game one team has a lead of ten (10) runs or more, the manager of the team with the least runs shall concede the victory to the opponent. NOTE: If the visiting team has a lead of fifteen (15) or ten (10) or more runs respectively, the home team must bat in its half of the inning.
The National League record was set by the Atlanta Braves with 29 runs against the Miami Marlins on September 9, 2020. The highest combined score in a game is 49 runs on August 25, 1922, when the Chicago Cubs defeated the Philadelphia Phillies 26–23.
If the game was a 7 inning game and the game was unplayable due to weather, leagues usually require the visiting team to complete at least 4 innings (12 outs) in order to mark the game as final. Whichever team was ahead after 12 outs will be considered the winner.
If a regulation game is terminated early due to weather, the results are considered final if the home team is leading. If the home team is trailing, the results are considered final if the game is not in the midst of an inning when the visiting team has taken the lead.
The mercy rule is most common in games such as baseball or softball, where there is no game clock and play could theoretically continue forever, although it is also used in sports such as hockey and American football. It is very rare in competitive sports beyond the high school level.
Some high school baseball games end before seven innings as a result of a mercy rule, though not every high school sports association has one. A mercy rule typically applies when one team is up by 10 or more runs past the midpoint of the game.
3.9 MERCY RULE a) After 5 complete innings, if a team is trailing by 10 runs at the end of an inning, the game will end and the win will be awarded to the team that is ahead. b) If the home team is down by 10 runs at the beginning of the inning, the home team must have their final at bat.
How many innings are needed for an MLB game? A matchup must make it through the top of the fifth inning at a minimum before it can be considered an official game. If the home team is trailing at that point, the bottom of the fifth inning must be played in order for the game to be marked official.
The Pawtucket Red Sox and the Rochester Red Wings, two teams from the Triple-A International League, played the longest game in professional baseball history. It lasted 33 innings, with 8 hours and 25 minutes of playing time.
If a game is rained out before play begins, it is rescheduled for a later date. If it has already begun and rain falls, several scenarios are used to determine the need to resume play: If a game has completed the top half of the 5th inning and the home team is ahead, the game can be deemed an official game.
When one team is 45 or more points ahead at the end of the first half or if a team secures a 45 point lead during the second half, the game is ended immediately.
Sensing that an official ruling was necessary as more and more baseball teams were formed, the Knickerbockers decided to form a committee in 1856 to tackle the issue. The desire for more competitive defense won out, and nine innings – and nine men – became the standard for good.
Mercy Rule: If a team is losing by 10 runs or more after completing their fourth half-inning at-bat, that team has the exclusive option of exercising the mercy rule and ending the game (not the other team or the umpire).
The scoring symbol “K” was first used in the scoring of an actual game in 1868. One reason the letter “K” was used because “K” was the prominent letter of the word strike. Another reason the letter “K” is used is that it is made with 3 strokes of the pencil, symbolizing the 3 strikes for the strikeout.
In 1897, the Chicago Colts of the National League defeated the Louisville Colonels, 36–7. The modern record (i.e., post-1900) for margin of victory was set in 2007, when the Texas Rangers defeated the Baltimore Orioles, 30–3.
Since 1900, only two teams have managed to score in each of nine innings of a game. On June 1, 1923, the New York Giants did it against the Philadelphia Phillies, winning 22-8.
The top NL mark since 1900 was the St. Louis Cardinals’ 28-6 win over the Philadelphia Phillies in 1929.
If at the end of a regulation game one team has a lead of ten (10) runs or more, the manager of the team with the least runs shall concede the victory to the opponent. The home team, if behind, must bat in its half of the inning. This should not be called the “mercy rule” or “slaughter rule.” It is the “Run Rule.”
For the MLB World Series and Postseason, games are also nine innings. High School baseball games are only seven innings, and Little League games are six. Softball games are only seven innings of play.
