What is interference?
There are different levels of interference when it comes to baserunners.
Per MLB rules, players on the batting team, including coaches, cannot get in the way of a player trying to field a batted ball. However, the rule states that if interference takes place on a batted ball, only the batter is declared out. All other runners must return to their previous bases.
The only time a runner is declared out is when a player or coach interferes with the fielder's right of way to throw a ball. If so, the player for whom the throw was intended to get out will be ruled out.
