Switch-hitter rules in baseball allow a player to bat from both the left and right sides of the plate during a game. The player must declare which side they will bat from before each at-bat, and they cannot switch sides once the pitcher is ready to throw the pitch. This strategy gives the switch-hitter an advantage by being able to bat from their stronger side against a pitcher's weaker side.
