Major League Baseball fans eagerly awaiting the introduction of the automated strike zone may have to wait longer than expected.

"The short answer is, I don't know what's going to happen going forward," MLB commissioner Rob Manfred said during a panel Wednesday, according to Evan Drellich of The Athletic. "I'm trying to get through this year's change. We have some work to do, I think, on (the automated ball and strike system, also known as ABS)."

MLB is introducing a few new rules in 2023 in hopes of speeding up the game and creating more on-field action. Those changes include the introduction of a pitch clock and PitchCom, restrictions on infield shifts, larger bases, and limiting pitcher pickoff attempts.
