An experiment with a technology system to challenge checked-swing calls started in the Class A Florida State League on May 20. That is not under consideration for MLB use in 2026. “I think we’ve got to get over the hump in terms of either doing ABS or not doing it before you’d get into the complication of a separate kind of challenge,” Manfred said. Baseball in 2028 Olympics Baseball is returning to the Olympics in 2028 after being played from 1992 to 2008 and then in 2021. MLB is considering whether to allow big league players to be used at the 2028 Games. It did not allow players on 40-man rosters to participate in the 2021 Olympics and many teams discouraged top eligible prospects from playing. “We made some progress with LA 2028 in terms of what it could look like,” Manfred said. “We have some other business partners that we need to talk to about, changes that would need to be made in order to accommodate the Olympics. I think we’re going to go forward with that process.”
