Far more than just recreation, baseball offers social, cultural, and political insights into history. For teachers, the goals of this article are threefold. First, this narrative is designed to provide the introductory content knowledge needed to develop a colorful lecture, structure a spirited discussion, or create a student project on the topic. Second, the detailed endnotes accompanying the paper offer instructors a guide toward accessible recent scholarship penned on ethnic aspects of the sport; many of the sources listed there provide bountiful tangential information for the investigative reader. Third, the collection of photographs featured alongside the narrative provides teachers with compelling visuals to utilize in the classroom--visuals that might enhance a lecture or capture students' attentions in an anticipatory set. In all, it is hoped that this essay will challenge instructors to consider sports history--our national pastime's history, in particular--as a ripe and engaging field for student intellectual inquiry, and will provide those teachers venturesome enough to try with the means necessary to incorporate a topic on baseball and race into their U.S. History curricula. (Contains 6 figures and 30 endnotes.)
