What Does K Mean in Baseball?
In baseball, K stands for a strikeout, which occurs when a batter accumulates three strikes during their at-bat and is called out.
- K is used on scorecards and statistics to denote this event.
- A backwards K is sometimes used to indicate a strikeout where the batter did not swing (called strikeout).
- Modern MLB statistics track Ks to evaluate pitcher performance, control, and dominance.
Fun Fact: The “K” was first popularized in the 19th century by Henry Chadwick, a baseball statistician and journalist. 📚
Why Is K Used Instead of S?
You might wonder why K is used instead of “S” for strikeout. The answer lies in history and clarity:
- “S” was already used for “Sacrifice” plays on scorecards.
- Henry Chadwick chose K, the last letter of “struck,” to symbolize a struck-out batter.
- The symbol has persisted and is now a universal shorthand in baseball.
How to Read K on a Scorecard
Understanding K on a scorecard is simple once you know the notation:

|---|---|
| K | Batter struck out swinging |
| backward K (ꓘ) | Batter struck out looking (did not swing) |
| K1, K2, K3 | Number of strikeouts by the pitcher in a game |
Example: If a pitcher has 8 Ks in a game, they struck out 8 batters.
Types of Strikeouts Represented by K
Strikeouts aren’t all the same. Here are the main types:
- Swinging Strikeout (K): Batter swings and misses three times.
