The NCAA announced this week that it will adopt an Automated Ball/Strike system for baseball across every collegiate division beginning next season, marking a decisive shift toward technology‑assisted officiating.
Teams will now have the ability to challenge called balls and strikes, a privilege that was previously reserved for human umpires, and the system was put through its paces during the Southeastern Conference’s May tournament before being cleared for nationwide use.
Alongside the digital strike zone, the association has mandated 18‑inch square bases at all venues, while still permitting the traditional 15‑inch size where facilities cannot accommodate the larger option, and every game will feature a double first base.
In Division I, a 30‑second timer will govern the interval between batters, as well as mound visits and offensive timeouts, aiming to streamline pacing and reduce idle time.
Pitchers will be limited to two disengagements per batter, with a third disengagement counted as a balk unless a pickoff attempt results in an out, and they must face at least three batters per inning unless the frame ends sooner.
Experimental Framework and Expected Impact
Conferences retain the freedom to experiment further, testing variations such as stricter disengagement limits and extended timers, while the NCAA emphasizes that these measures are provisional and subject to evaluation before any permanent adoption.
