Prediction markets put the probability at 27%: Will the Miami Marlins have the highest ABS success rate during the 2026 MLB regular season. Currently, markets see this as unlikely (27% YES).
The Automated Ball-Strike (ABS) Challenge System, powered by Hawk-Eye tracking technology, debuted across MLB at the start of the 2026 season, giving teams a limited number of challenges to overturn umpire ball-strike calls. The question of whether the miami marlins have the highest abs success rate during the mlb regular season hinges on how Miami's challenge accuracy stacks up leaguewide. As of ESPN's Aug 18 tracker, the Marlins posted a 56.1% overall success rate, ranking 9th, trailing the Philadelphia Phillies (57.0%, 7th) and sitting behind clubs like the New York Yankees (55.1%, 11th) in the broader standings, though Miami's 60.1% catcher figure ranked 13th.

Individual performance has shaped Miami's numbers. Catcher Agustin Ramirez, who had accumulated 22 overturned calls against him — the second-most in MLB — was optioned back to Triple-A, a roster move that reflected the Marlins' uneven early results behind the plate. By contrast, the leaguewide leaderboard has been dominated by the Detroit Tigers' Dillon Dingler, who went 15-for-17 for an MLB-high 88.2% success rate, followed by the Rockies' Hunter Goodman at 76.9% (20-for-26). With 34 catchers logging at least 10 successful overturns, the field competing for the top team record remains crowded and volatile. [The Analyst, May 6]
Preseason projections did not favor Miami on this front: CBS Sports predicted the Yankees would post the best ABS challenge success rate in baseball, while forecasting the Marlins to enter September in third place in the NL East. For the miami marlins have the highest abs success rate during the mlb regular season to resolve YES, Miami would need to close the gap on the Phillies and other front-runners over the season's final stretch. With sample sizes still growing and single roster moves swinging team rates, the odds reflect a Marlins club that is competitive but not yet leading the ABS standings. [CBS Sports, Mar 24]
