To read a baseball box score, start with the line score for the final result and runs by inning, then check each hitter’s batting line (AB, R, H, RBI), each pitcher’s line (IP, H, R, ER, BB, SO), and the notes for home runs, errors, and double plays. Position numbers such as 6-4-3 describe which fielders handled the ball.
Key takeaways
- The line score shows runs, hits, and errors by team and runs by inning.
- Batting lines use AB, R, H, and RBI, while pitching lines use IP, H, R, ER, BB, and SO.
- Fielding numbers run from 1 for pitcher to 9 for right fielder.
- Game notes list the key plays that changed the score.

A baseball box score is a compact summary of everything that happened in a game. At first it looks like a wall of letters and numbers, but it follows a clear pattern. Once you understand it, you can follow any game without watching a single pitch. This guide explains each section, the abbreviations, the fielding position numbers, and how to read a simple example.
What Is a Box Score?
A box score lists the final score, each team’s inning-by-inning runs, every player’s batting line, every pitcher’s pitching line, and notes on key events such as home runs, doubles, errors, and double plays. It is the standard record of a game, and every sports site and newspaper prints one.
The Four Main Parts of a Box Score
- Line score: runs by inning and the totals for runs (R), hits (H), and errors (E).
- Batting lines: what each hitter did.
- Pitching lines: how each pitcher performed.
- Game notes: extra details such as home runs, doubles, stolen bases, double plays, and attendance.
The Line Score
Here is a simple made-up example. It is for illustration only and does not describe a real game.
| Team | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | R | H | E |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Visitors | 0 | 1 | 0 | 0 | 2 | 0 | 0 | 1 | 0 | 4 | 9 | 0 |
| Home | 1 | 0 | 0 | 2 | 0 | 0 | 0 | 0 | 0 | 3 | 7 | 1 |
The visiting team is listed first and bats first in each inning. Here they won 4 to 3. The home team made one error. If the home team is ahead after the top of the ninth, the bottom half is not played, and you may see an “X” in that box.
Batting Lines Explained
| Column | Meaning |
|---|---|
| AB | At-bats |
| R | Runs scored |
| H | Hits |
| RBI | Runs batted in |
| BB | Walks |
| SO | Strikeouts |
| LOB | Runners left on base |
A line such as “4 1 2 1” under AB, R, H, RBI means the player batted four times, scored once, had two hits, and drove in one run. Players are listed in batting order, and substitutes appear indented below the player they replaced.
Pitching Lines Explained
| Column | Meaning |
|---|---|
| IP | Innings pitched, with .1 meaning one out and .2 meaning two outs |
| H | Hits allowed |
| R | Runs allowed |
| ER | Earned runs allowed |
| BB | Walks allowed |
| SO | Strikeouts |
| HR | Home runs allowed |
Letters beside a pitcher’s name show decisions: W for win, L for loss, S or SV for save, and H or HLD for hold. For a deeper explanation of stats like ERA and WHIP, see our guide to baseball player stats.
Fielding Position Numbers
Scorekeepers use numbers for each defensive position. These appear in play descriptions and score sheets.
| Number | Position |
|---|---|
| 1 | Pitcher |
| 2 | Catcher |
| 3 | First base |
| 4 | Second base |
| 5 | Third base |
| 6 | Shortstop |
| 7 | Left field |
| 8 | Center field |
| 9 | Right field |
A “6-4-3 double play” means the shortstop fielded the ball, threw to the second baseman, who relayed to the first baseman.
Common Box Score Abbreviations
| Abbreviation | Meaning |
|---|---|
| 2B, 3B, HR | Double, triple, home run |
| SB, CS | Stolen base, caught stealing |
| HBP | Hit by pitch |
| SF, SH | Sacrifice fly, sacrifice bunt |
| DP | Double play |
| WP, PB | Wild pitch, passed ball |
| E | Error |
| T | Time of game |
How to Read a Box Score in 60 Seconds
- Check the line score for who won and when the runs were scored.
- Look at the winning and losing pitchers and the innings they threw.
- Scan the batting lines for multi-hit games and the RBI leaders.
- Read the notes for home runs and key plays.
- Check errors and double plays to see if defence changed the game.
Box Score vs Play-by-Play
A box score summarises the game, while a play-by-play lists every plate appearance in order. Use the box score for a quick overview and the play-by-play to understand how and when specific runs scored. Official game data is available on MLB.com, and the MLB glossary explains additional terms.
Tips for Beginners
- Learn the abbreviations first, since most confusion comes from them.
- Follow one team for a few games, so the format becomes familiar.
- Try keeping your own score sheet while watching a game.
- Do not judge a player on one game. Season totals tell a clearer story.
