10 Baseball Rules That You Must Know

A pinch hitter typically replaces the batter to use a beneficial matchup with the opposing pitcher. To increase speed or develop baserunning abilities, a pinch runner takes the place of a baserunner.


Pinch hitters and runners are not subject to penalties, but unless injured, they usually stop the player who was substituted from playing again.

Making a Tag

Runners must tag up after a ball gets caught by making contact with the base they were on before the catch. This rule keeps runners from moving forward until the football is seen; if they do so before the ball has been caught, they risk being called out.


This rule comes into play when a fielder catches a fly ball hit by a batter. Baserunners must “tag up” by returning if they had been taking up at the moment of the catch before attempting to make it to the next base.


A fielder can record an out if they successfully catch a fly ball and the runner leaves the field before “tagging up.” The fielder can then toss the ball toward the base the runners left early. 

A runner must return to first base and risk being tagged off by the fielder if they leave the field before the fielder can catch the ball.

Double Ground Rule

When a batted ball crosses an outfield fence or gets stuck in a permanent object in the playing area, a ground rule double is given. This rule offers a standard result for balls that do not stay in play because of their unusual path or contact with the field.


When a batted ball crosses an outfield fence or gets lodged in a permanent protest on the playing field, preventing the opposing team from making a play with the ball, this rule is applied.


The hitter and any runners on base are given two bases from the moment the pitch is made when the ground rule double is called. For example, the batter advances to second base if he hits the ground rule double and there are no runners on base. 

If there are baserunners, each receives two bases and their starting position at pitching.

Review of Video Replay

It is referred to as instant replay or video replay review. The umpires can use video footage to verify the accuracy of specific calls made on the field. This regulation wants to reduce incorrect calls and advance the game’s fairness.


When a call on the field is contested, such as if a ball had been fair or foul, if the catch was made, or if a runner was safeguarded or out, this rule is applied.


Video replay reviews are not penalized in any way. The video evidence supports the decision if a call is reversed after review. A challenge could end in losing an opportunity if it is unsuccessful. Each team is usually allowed several chances to challenge each other per game.

Rule of the Ambidextrous Pitcher

A pitcher may change their throwing arm during an at-bat as long as they alert the umpire and allow the batter to adjust, according to the ambidextrous pitcher rule. Pitchers who can throw with both hands are allowed by this rule, which also creates clash and strategic advantages.


This rule is used when a pitcher plans to alternate between putting to a batter via one side (e.g., a right-handed) followed by the other (e.g., left-handed) during an at-bat.


Regarding the ambidextrous pitcher rule, there are no consequences. But the pitcher has to let the umpire know and give the batter time to adjust to the new throwing arm. Before a pitch goes to the batter, the switch must happen. This rule adds a surprise and tactical element to pitching because batters may have distinct advantages and disadvantages against right-handed and left-handed pitchers.
