The debate over merit and institutional inclusion in professional sports officiating has arrived at a precise set of numbers this season. Ball-and-strike data compiled by UmpScorecards places Jen Pawol, Major League Baseball's first female home plate umpire, 89th out of 91 qualified umpires in overall accuracy through 2026, reviving a controversy that began when she reached the majors in 2025.
What the data shows
UmpScorecards measures every called ball and strike against MLB's Statcast strike zone, grading umpires on overall accuracy, consistency, and performance relative to the expected difficulty of pitches called. By those metrics, Pawol carries a 91.8% overall accuracy rate and a 93.1% consistency rating, with an accuracy-above-expected mark of -1.6%. The league average for umpire consistency sits at 94%.
The numbers alone would draw attention. The incidents behind them have amplified the story further.
On-field incidents that drew scrutiny
On June 16, in the St. Louis Cardinals versus Minnesota Twins game, Pawol had three ball calls overturned in the top of the first inning. A 2026 spring training contest between the Cincinnati Reds and Cleveland Guardians became widely circulated online when a broadcaster noted that a call Pawol ruled a ball was overturned, describing the pitch as having been right down the middle of the plate.
The most recent controversy came July 13 in the San Diego Padres and Toronto Blue Jays game. Padres batter Sung-Mun Song was not permitted to challenge a called strike, and Pawol shortly afterward called a balk that forced in a run for the Padres. Her overall consistency for that game, per UmpScorecards, registered at 88%, against the league average of 94%.
Observers at that game noted that fellow umpires appeared to step in before managers could engage Pawol directly on disputed calls. No confirmed explanation was offered for the pattern.
The wider officiating picture
Against the backdrop of Pawol's statistics, the comparison at the bottom of the league rankings carries its own weight. CB Bucknor, currently rated the worst-performing umpire in the league by UmpScorecards, has accepted a buyout and will retire at the end of the season. Commentator Zach Dean has noted that timing as relevant context for the accountability debate now surrounding the umpiring corps as a whole.
Pawol has the remainder of the season to improve her standing. The current record is a 91.8% accuracy rate, a -1.6% accuracy-above-expected mark, and a ranking of 89th among 91 qualified umpires in a league that made her promotion a stated milestone just one year ago.
