Understanding Umpire Scorecards
Umpire scorecards have become an essential part of the conversation in Major League Baseball (MLB) and across the wider world of baseball analysis. You may have heard about them during broadcasts, seen them shared on social media, or stumbled across them when researching umpire statistics. But what exactly are umpire scorecards? How are they created, what do they measure, and why do they matter?
Let’s explore these questions, break down the details, and help you understand how umpire scorecards work, their significance, and how you can interpret one like a pro.
What Is an Umpire Scorecard?
An umpire scorecard is a report that evaluates the performance of the home plate umpire during a baseball game. Specifically, it breaks down how accurately and consistently the umpire called balls and strikes, comparing their decisions with what should have been called according to an established rulebook strike zone (usually determined by sophisticated pitch-tracking technology).
In simple terms, an umpire scorecard tells you:
- How many calls the umpire got right or wrong
- The most impactful calls (for either team)
- Patterns or tendencies in mistake locations
- A fairness assessment (did calls benefit one side?)
Think of it as a detailed report card showing an umpire’s performance, promoting transparency and accountability.
How Are Umpire Scorecards Generated?
Creating an umpire scorecard may seem complicated, but here’s a step-by-step overview that breaks down the process:
1. Pitch Tracking
- Every pitch in the MLB is tracked using precise 3D technology (such as Statcast or PITCHf/x).
- The data records the pitch’s exact location as it crosses the plate, as well as speed, spin, and other characteristics.
2. Compare Umpire Call with Pitch Location
- Was the pitch called a ball or a strike?
- Where did the pitch actually cross in relation to the official strike zone?
- The technology determines whether the pitch “should” be a ball or strike.
3. Recording and Scoring
- Each pitch is logged as:
- Correct Call: Umpire’s decision matches the data.
- Missed Call: Umpire’s decision was incorrect according to the data.
4. Aggregating Results
- After the game, all pitches are tallied.
- The total accuracy rate is calculated—the percentage of total pitches called correctly.
- Additional metrics are computed (which we’ll cover below).
5. Presenting the Scorecard
- Results are visualized in easy-to-read graphics and summaries.
- Locations of missed calls are often mapped to help visualize trends.
- Impactful calls and overall influence on the game are assessed.
Key Metrics and Terms on Umpire Scorecards
Understanding any scorecard means knowing what each statistic tells you. Here’s a breakdown of typical metrics you’ll find:
1. Overall Accuracy
- Percentage of all called balls and strikes that the umpire got right.
- Example: If 95 out of 100 calls were correct, the accuracy is 95%.
2. Consistency
- Measures how evenly the umpire applies their personal strike zone to both teams.
- Even if slightly off from the official zone, did both sides get treated the same?
3. Missed Calls
- Number (or percentage) of balls called as strikes, and strikes called as balls.
- High-profile missed calls are often highlighted.
4. Most Impactful Missed Call
- Identifies which incorrect call had the greatest effect on the game’s outcome (e.g., a missed strike that led to a walk that scored the winning run).
5. Favor
- Indicates if either team received a net advantage from incorrect calls.
- Measured by changes in expected runs or win probability, depending on the context of each missed call.
6. Zone Visualization
- Graphics showing the actual strike zone versus where balls and strikes were called.
- Hot spots where mistakes occur are often shaded.
Benefits of Umpire Scorecards
Why do umpire scorecards matter? Here are the big benefits:
- Transparency and Fairness: Fans and teams can see, with data and visuals, how umpires performed.
- Training and Improvement: Umpires themselves use scorecards to identify areas to improve.
- Discussion and Accountability: Scorecards encourage healthy debate and can pressure leagues for better umpiring or the adoption of automated systems.
- Entertainment: For fans, it adds another layer of engagement and analysis.
- Historical Record: Over time, patterns emerge, showing strengths or weaknesses of individual umpires.
Challenges and Considerations
While umpire scorecards are popular and useful, there are some important limitations and challenges to keep in mind:
- Technology Limitations: Pitch tracking isn’t flawless, and there’s always a margin of error.
- Human Factors: Some believe that a consistent “personal strike zone” is more important than perfection by the rulebook.
- Sample Size: A single game may not reflect an umpire’s long-term ability.
- Interpretation: Not all missed calls matter equally; context is everything.
- No Direct Consequences: Scorecards alone don’t result in disciplinary actions without broader review.
How to Read and Interpret an Umpire Scorecard
If you’re looking at an umpire scorecard for the first time, follow these simple steps:
-
Look at the Overall Accuracy
Check the main accuracy number—this is the quickest way to see how well the umpire performed overall. -
Review Consistency
Scan whether both teams were treated equally even if the zone was ‘off’ from the rulebook. -
Check High-Impact Calls
Notice which calls had the biggest effect on innings, rallies, or runs scored. -
Analyze the Strike Zone Visualization
See where the umpire missed calls—are they always low, outside, or in one spot? -
Consider Context
Read about when missed calls happened (e.g., bases loaded, two outs). Timing can make a single call far more significant. -
Compare with Umpire’s Norm
Is this a usual performance for this umpire, or an outlier?
Practical Tips for Using Umpire Scorecards
Whether you’re a coach, player, bettor, or fan, here are some smart ways to use umpire scorecard data:
- Look for Patterns: Over many games, does an umpire always have a “wide” strike zone? Does it favor pitchers or hitters?
- Prepare Accordingly: Teams can tailor their approach or game plan based on an umpire’s tendencies.
- Add Context to Game Discussions: Reference the scorecard when talking about controversial game moments.
- Staying Objective: Remember to analyze the scorecard, not your fan emotions (we all want our team to get the calls!).

Do umpire scorecards influence umpire assignments or promotions?
Major League Baseball tracks umpire performance closely, but public scorecards are just one piece of the puzzle. While consistently poor or exceptional scorecards can raise or lower an umpire’s reputation, formal assignments or promotions are based on a wider range of data and league evaluations.
