Question: what are the k's in baseball?
Answer: In baseball scorekeeping, a swinging strikeout is recorded as a K, or a K-S. A strikeout looking (where the batter does not swing at a pitch that the umpire then calls strike three) is often scored with a backwards K (ꓘ), and sometimes as a K-L, CK, or Kc (the 'c' for 'called' strike).
