The study conducted a semi-structured interview with 7 batting experts who could tell us about their batting experience in the past.

The generated categories were (1) Formation of competing image, (2) Sophistication of competing image, (3) Selection of tactics, and (4) Formation of batting view. The following 4 items were revealed by the generated models. (1) A batter can reduce a burden to consider tactics when maintaining a wide range of basic tactics. (2) A batter selectively gains a necessary technique for carrying out tactics. (3) A batter selectively gains useful information for carrying out individual tactics by understanding information through a batting experience in the past. (4) A batter develops a practical wisdom of individual tactics by reflecting on batting experience. The following 3 items were presented as a suggestion to a batting training.
