Earlier this month, Major League Baseball announced several rule changes to take effect with the 2023 regular season. Briefly, they are:
- A pitch clock
- Limitations on defensive shifting
- Larger (18 inch by 18 inch) bases
There’s going to be one other potential future rule change for MLB regular season games which is going to be tested in two parks in the Arizona Fall League, per a MLB press release:
The Automatic Ball-Strike (“ABS”) Challenge System that began in the Florida State League in 2022 will be implemented on the experimental level at the Arizona Fall League for games played at Salt River Fields and Chase Field.
