MLB to Experiment in Minors with Technology Challenges for Checked Swings
- Starting Tuesday, Major League Baseball will launch a pilot program in the Florida State League at the Single-A level that allows teams to use technology to challenge checked swing calls.
- This pilot follows prior experiments in last year's Arizona Fall League and spring training, where MLB tested automated systems including Hawk-Eye technology for ball-strike and checked swing calls.
- Teams at bat or defense can challenge checked swing calls measured by the bat head’s angle relative to the knob, with a 45-degree threshold defining a swing for right-handed hitters.
- Teams may challenge checked swings until one fails, and a video of the Hawk-Eye’s maximum bat angle will be displayed on the ballpark video board during the review.
- MLB vice president Joe Martinez described the initiative as an initial phase of testing, while Commissioner Manfred indicated that the technology might be implemented during the 2026 regular season, though nothing is certain yet.
