For this book I went to games at Fenway Park, Camden Yards, and Jacob’s Field. I saw inside Shea Stadium’s locker room. Mostly I took the subway to Yankee Stadium and watched games and sketched. There’s something about the rhythms of baseball that lends itself to sketching. In college I wrote my senior essay on Ebbets Field, about how important a ballpark can be to its community. In this book I looked at the community inside the ballpark: groundskeepers, trainers, umpires, and fans.
