Major League Baseball will test robot umpires as part of a challenge system during spring training at 13 ballparks hosting 19 teams, which could lead to regular-season use in 2026.
Major League Baseball will test robot umpires as part of a challenge system during spring training at 13 ballparks hosting 19 teams, which could lead to regular-season use in 2026.
MLB has been experimenting with the automated ball-strike system in the minor leagues since 2019 but is still working on the shape of the strike zone.
An agreement for big league use would have to be reached with the Major League Baseball Umpires Association, whose collective bargaining agreement expires Dec. 1.
“I would be interested in having it in ‘26,” baseball Commissioner Rob Manfred said Wednesday after an owners’ meeting. “We do have a collective bargaining obligation there. That’s obviously a term and condition of employment. We’re going to have to work through that issue, as well.”
Manfred said the spring training experiment will have to be evaluated before MLB determines how to move forward.
“There’s two sides to that test," he said. "It’s what the clubs think about it and also what do the players think about it? And we’re going to have to sort through both of those.”
Triple-A ballparks used ABS this year for the second straight season, but there is little desire to call the strike zone as the cube defined in the rule book and MLB has experimented with modifications during minor league testing.
