Experiments with robot umps, longer mound distance delayed

NEW YORK (AP) — Robot umpires will get some more warmup time.
Major League Baseball and the Atlantic League said Wednesday that the experiment with radar-tracking technology to call balls and strikes won’t be used when the independent minor league starts play on April 25. Instead, the technology “will be implemented gradually over the course of the 2019 season.” No date for the start was announced.
Plate umpires will wear earpieces and be informed of ball and strike calls
