Question: what is the difference between a forward k and backward k in baseball?
Answer: In baseball scoring, a backwards K represents a called strikeout (i.e. batter watched strike 3 go by without swinging) whereas a forwards K is a swinging strikeout. ... the umpire then calls strike three) is often scored with a backward K, and sometimes as a K-L, CK, or Kc (the 'c' for 'called' strike).
