This study conducted a video evaluation experiment involving a total of 10 participants, comprising fans and non-fans of Japan Professional Baseball's Central League teams, to examine the impact of game outcomes on subjective quality evaluations and emotional changes. The analysis revealed that fans' quality evaluations and emotions were significantly affected by the win-loss results of their supported teams, showing a tendency for subjective quality ratings and positive emotions to elevate following a victory. Conversely, fans exhibited higher baseline levels across all indices compared to non-fans, and even in games where their supported teams did not play, they demonstrated higher ratings and more positive emotions.
