Rob Manfred: Robot umpires may be tested at spring training - ESPN
ARLINGTON, Texas — Major League Baseball hopes to test robot umpires as part of a challenge system during spring training next year, making an automatic-ball-strike component possible as early as 2026. But MLB commissioner Rob Manfred still seems far from committing to that date, saying Tuesday that the league has «technical issues surrounding the definition of the strike zone» that need to be ironed out before it is even tested by major league players.
