just a side note, the MLB tracking system (ZE system) judges the ball from the time it crosses the plate, so initially that pitch that catches the bottom of the zone but hits the dirt is ruled as a missed pitch for the PU... obviously they don't want that called a strike so the supervisors go in each morning and when they check the performance of the umpires they reverse that decision and recalculate the PU's accuracy score so it is scored as a ball
edit: the balls and strikes system they use is the ZE system, the system they use for calls in the field is the SURE system
