The Backwards K in Baseball

A backwards K means the batter struck out looking: strike three was called and he never swung. A regular K is a strikeout swinging. Here is where the K comes from, how to score every kind of strikeout, and a backwards K you can copy.

Keyboards do not have one, but this character looks like a backwards K and pastes into texts, posts, and spreadsheets.

Why Is a Strikeout a K?

It comes from Henry Chadwick, the 19th century baseball writer credited with creating the box score. In his day a batter who struck out was said to have “struck,” and S was already taken for the sacrifice. So Chadwick used K, the last letter of struck, and explained in his 1874 manual that K was easier to remember in connection with the word than S would be.

The K stuck for 150 years. Flipping it to show a called third strike came later, as a scorekeeper’s shorthand, and today you will see backwards K signs held up in the stands every time an ace freezes a hitter.

How to Score Every Kind of Strikeout

Write the K in the batter’s box for that at-bat. The direction of the K tells you how strike three happened.

KStrikeout swinging. The batter swung and missed at strike three, or fouled off a two-strike bunt.
ꓘStrikeout looking. The umpire called strike three and the batter did not swing.
K-WPStrike three got away on a wild pitch and the batter reached first.
K-PBStrike three got away on a passed ball and the batter reached first.
K 2-3Strike three was dropped and the catcher threw to first for the out.

A dropped third strike still counts as a strikeout for the pitcher even when the batter reaches safely, which is how a pitcher can record four strikeouts in one inning. The numbers in 2-3 are position numbers, catcher to first base; see baseball position numbers and the rest of the scoring symbols.
