Fantasy sport consumer behavior research is a burgeoning area of inquiry as this growing segment of sport fans exhibits unconventional, yet robust media consumption habits. In addition, consumer motivation and market segmentation represent core principles within the study of marketing, yet the integration of these two essential concepts with regard to sport consumers is limited. The purpose of this study was to explore fantasy baseball motives, develop a motive-based taxonomy of users, and quantify the differences between segments through an examination of mediated sport consumption. An exploratory hierarchal cluster analysis with a subsequent K-means analysis was conducted to determine the number of segments. Additionally, a MANOVA was performed to ascertain behavioral differences between the motive-based clusters. Four distinct segments emerged with statistically significant differences between each with regard to mediated consumption intentions. The following paper addresses theoretical and practical implications for academics and practitioners. Future research is also suggested.
