Editor's note: Twice a week during this sports hiatus, we'll answer questions that Bay Area sports fans long have debated in "Ever Wonder?"  This installment: How did the letter "K" come to stand for strikeout?

HR stands for home run. RBI stands for runs batted in. ERA stands for earned run average.

You can learn about how "K" came to stand for strikeout in the video at the top of this article.
