Happy Opening Day, everyone. Baseball is back. SOL GITTLEMAN and PHIL WOOD discuss teaching college courses on baseball and baseball history, two of 400 courses taught about the sport. Librarian TIM WILES (who worked many years at the Baseball Hall of Fame) tells of baseball research done in his town. Tim sets the mood by reciting "Casey at the Bat," a poem he's performed for audiences for 25 years. Stay to the end for a farewell to a recently deceased ex-player and a follow-up -- far off in the Middle East -- to the recent episode on the 50th anniversary of Ali-Frazier I.
