Strikeouts measure the total number of at bats in which the player accumulates three strikes without getting a hit or earning a walk.
More about Strikeouts Leaders
Player strikeouts have been increasing for years, though they have especially spiked in the last few years. In 1990 a total of 43 players struck out 100 times or more; in 2013 that number was up to 105. Strikeouts used to have a negative connotation to them, almost as though batters should be embarrassed if they were unable to make contact. Now, a strikeout is not thought of as very different from any other routine out. Seasons of posting 200 strikeouts now are not completely unheard of, either. There is not much of a difference among batter leaders in strikeouts between the two leagues.
