A ground ball skips foul past third base in Dodger Stadium.
Ground Ball Goes Foul
A ground ball that goes foul is declared a dead ball as soon as an umpire declares that it is foul. To do so, an umpire will indicate a foul ball by pointing towards foul territory1. To further reiterate that the ball is dead, umpires will usually raise their arms to their heads with their palms out— perhaps as if they were being held at gun point and had been told to stick their hands up, though that’s generally not the vibe of your average foul ball. Oftentimes, because foul balls tend to be fairly obvious, the umpires will skip the pointing and go directly to the hands-up part of the signal.
Fair/foul calls can only be reviewed by replay if the crux of the call happens “behind” the spot where the base umpires usually stand. This means that most ground balls called foul cannot be subject to replay, as they will cross the fair/foul threshold in front of the umpires.
A ground ball that goes foul must be collected and removed from the field before play resumes. If the count had less than two strikes before the foul ball, then the foul ball results in a strike. If there were already two strikes, then the count does not advance on a foul ball— unless, of course, the ball was struck foul by a bunt. A bunted foul ball is always a strike, regardless of the count beforehand.
