Brewers must solve their ABS challenge issue before postseason arrives

The Milwaukee Brewers have unexpectedly struggled with the new ABS challenge system implemented in 2026, despite being expected to excel given their reputation for baseball intelligence and discipline. Through early September, the Brewers rank last in challenge rate at 3.0% while posting the fifth-worst success rate at 44%, and their actual challenge rate lags their expected rate by 1.2 percentage points—the largest gap in baseball. Of their 49 successful challenges, only 13 eliminated strikeouts and six resulted in walks, suggesting they are challenging at ineffective moments. With three weeks before the postseason, Milwaukee must quickly improve their approach to this new rule or risk losing a potential competitive advantage.
