Reds Lead Umpire Error Stats in First Half of MLB Season

Umpire Audit Shows Massive Error Toll

The most recent Umpire Auditor Twitter/X account report reveals that MLB umpires missed 14,441 calls during the first half of the 2026 season. Out of those missed calls, officials overturned 3,217 plays, a figure that highlights the system’s attempt to correct obvious mistakes. These numbers provide a clear picture of how often human judgment can diverge from the precise strike zone.

The audit also zeroed in on the Cincinnati Reds, showing that several of the missed calls involved the franchise. However, the data notes that none of the ten worst‑called third‑strike plays were Reds scenarios, a detail that spares the team from the most egregious errors. The disparity underscores how certain clubs may be more affected by umpire inconsistencies.

In addition to the missed calls, Umpire Auditor posted video demonstrations that illustrate misses ranging from 3.9 inches to 5.99 inches beyond the strike zone on called third strikes. Some of those pitches were successfully challenged, while others remained unchecked, indicating variability in how managers use the replay system. This visual evidence offers fans a tangible sense of how far off‑target some decisions can be.

Reds Rookie Sal Stewart Shines in ABS Challenges

Reds rookie All‑Star Sal Stewart has emerged as the league leader in successful ABS challenges, topping the list with 23 successful overturns according to Baseball Savant data. Stewart’s ability to pinpoint umpire errors has made him a key weapon in Cincinnati’s strategy to contest close plays. His high success rate suggests the Reds have a catcher who can effectively leverage the technology to change outcomes.

The impact of Stewart’s performances is evident when looking at the broader context of MLB catcher challenges. Among all catchers who have logged at least 50 ABS challenges, the Reds’ Tyler Stephenson tops both the win column (62) and the success percentage (73%). This dual dominance showcases how Cincinnati’s receivers are driving the team’s challenge efficiency. The team’s emphasis on using data‑driven reviews appears to be paying dividends on the field.

Final Thoughts on Reds’ Challenge Success

When the season’s midway point arrived, the Reds had already become a focal point for umpire review discussions. Their players, especially Stewart, have demonstrated a keen eye for spotting errors, turning close calls into potential wins. The aggressive use of technology by Cincinnati’s dugout shows a broader shift in how teams approach officiating disputes.

Looking ahead, the trends captured in the audit suggest that clubs investing in advanced review tools may gain a measurable edge. If Stewart’s 23 successful challenges continue at a similar pace, the Reds could reshape expectations for catcher-led contests. The data also underscores that while the Reds benefit from these reviews, the overall league still wrestles with a high volume of missed calls.

Overall, the Umpire Auditor findings provide a snapshot of a season still searching for consistency. By highlighting the Reds’ performance in both missed-call metrics and successful challenges, the story offers a template for how franchises can leverage scrutiny to improve outcomes. Readers interested in the evolving role of replay and ABS challenges will find the Reds’ experience particularly compelling as the second half of the schedule approaches.
