Despite serving as a secondary plot to the love story, the baseball aspects of For Love of the Game are pretty accurate. It's the little things, like the Tigers having home and away hats and the time Billy Chapel spends on the bike at Spring Training- that stuff is authentic. Costner's a baseball guy- he knows it's in the details.
One of the most ridiculous, yet usually overlooked, scenes shows John C. Reilly wearing his New Era 59/50 Tigers hat up to Costner's hotel room. You're a Big League catcher and you wear your game hat struttin' around New York City? I stopped wearing my team's game hat in public in Little League, and even then people gave me crap for it. Hey, better the hat than his catcher's helmet forward I guess. (Kinda ridiculous he's even in a movie where he's not screaming "Shake'n'Bake!" or wearing a Chewbacca mask.)
