Pros and cons of MLB's robo-ump experiment: How ABS system worked during spring training debut ABS will not be used in the majors this coming season, but it seems like only a matter of time ...

GOODYEAR, Ariz. — Cincinnati Reds manager Terry Francona says he’s told players not to use the experimental Automated Ball-Strike System in spring training.

The MLB will continue testing the ABS challenge system after an initial test run in spring training.

And now, the league is prepared to put ABS to the test on a big stage. According to ESPN, the ABS challenge system will make a return for Tuesday's All-Star Game at Atlanta's Truist Park.

The Astros will have limited exposure to MLB's automated ball-strike challenge system this spring, and manager Joe Espada wants his players to take advantage.
