This study investigated the fans’ knowledge of team social responsibility (TSR) as well as the motivation and intentions associated with TSR. Other correlates included in the conceptual model are the fans’ value orientation of universalism, sport involvement, and team identification. A questionnaire was administered at three Chinese Professional Baseball League (CPBL) games in Taiwan (n = 520). It was found that perceptions of team social responsibility were linked to TSR-induced motivation to watch baseball. Universalism values, spectator sport involvement with CPBL, and team identification were found to be positively related to TSR knowledge, TSR-linked motivation, and TSR-linked intentions. The results provide useful insights that professional baseball teams can use to pursue a goal of sustainability and to ensure a uniquely engaged fan base.
