MLB Plans New Challenge System to Clarify the Definition of a Swing
Major League Baseball is developing a challenge mechanism, similar to the ABS system, to resolve disputes over what constitutes a swing.
The league intends to introduce a formal review process aimed at eliminating the current ambiguity surrounding swing judgments. Officials hope the new system will function like the existing ABS challenge, providing teams a way to contest calls. By standardizing the definition, MLB seeks to reduce on-field controversy and improve consistency across games. The proposal is still in the planning stage and will require approval before implementation.
Why it matters
A clearer swing rule would reduce game-changing disputes and make baseball more consistent for players and fans.
