Walk on a Wild Pitch/Passed Ball

When there are 3 balls in the count, there are runners on base, and the pitcher uncorks a pitch that doesn't get caught cleanly (i.e. a wild pitch or passed ball), the result is not only a walk, but a walk in which the runners might move up multiple bases.

First, the batter: as mentioned previously, the batter gets a walk, otherwise known as a base on balls. A walk simply means that the batter now automatically takes first base. Any runners in a force situation also move up a base, but since the ball is still live, they can attempt to take additional bases— and any runners not forced can always take off, as well.

If the defense gets control of the ball quickly enough, they can always try to go after a (non-forced) baserunner. Or, they may just stick the ball in their back pocket, so to speak, and prepare for the next batter.
