In MLB’s new ABS (Automated Ball-Strike) challenge system, each team starts with two abs challenges per game, so there are four total challenges available between both teams in a standard nine-inning game.

However, in real usage the number of actual abs challenges you see per game has been a bit higher in testing and spring training:

  • In 2025 spring training trials of the ABS challenge system, games averaged about 4.1 challenges per game between both teams.
  • Another report from spring 2026 noted about 4.5 challenges per game across both teams, with the expectation that this will drop slightly once the regular season begins and teams get more strategic.
  • At Triple-A, where a similar challenge setup was used, the number also settled around four total challenges per game between both sides.

Quick Scoop

  • Official rule: 2 abs challenges per team per game in MLB’s 2026 system (more can be added in extras under specific rules).
  • What actually happens:
    • Around 4–4.5 abs challenges used per game in recent spring training data. Players have been more willing to test the system before the regular season really counts.
* Analysts expect that number to settle closer to 4 per game as strategy improves and players save challenges for high-leverage spots.

So if you’re searching “how many abs challenges per game” for the latest news and forum discussion: the rulebook says 2 per team, but in practice you’ll usually see around four total per game based on recent testing and early 2026 data.

TL;DR:

  • Rule limit: 2 abs challenges per team per game.
  • On-field reality so far: Roughly 4 total abs challenges used per game across both sides.
