Walk
If the count has three balls when a pitch comes in, and the pitch is called a ball, the result is a walk. Otherwise known as a base on balls, a walk simply means that the batter now automatically takes first base. You can also get a walk without a pitch if there are three balls in the count, and the pitcher commits a pitch timer violation, resulting in a fourth ball.
On a walk, any runners in a force situation also move up a base. If the runners were attempting to steal a base, they automatically get that base, unless it’s not a force— for example, if there’s a runner on second but not on first, that runner isn’t forced anywhere on a walk, so if they are attempting to steal third on ball four, the defense can still make a play on them.
The ball does not go dead on a walk, especially if the defense puts the ball into play trying to catch a non-forced base stealer. Once the batter reaches first, they become a runner, and are in play for the defense, unless someone calls time1.
