The purpose of this research was to examine the effect of a baseball captain’s remarks and examine the transformation of his leadership capabilities with a university baseball club. The investigation methods in this research included analyzing the captain’s remarks during a team meeting, interviewing the captain, and conducting a questionnaire about leadership. The following results were revealed.

1. The captain’s primary remarks concerned providing feedback to members of the team. At the onset, the captain’s remarks were aimed at creating and developing a new team. However, the captain’s remarks gradually increased to be more about improving motivation and having players be “conscious” of the game as the actual game approached.

2. The captain had an ideal concept of what a team should be and he displayed his leadership based on this ideal. As a result, the team gradually got closer to his ideal because of the captain’s consistent display of leadership that emphasized his policy.
