The game of baseball has itself inspired many metaphors and, in fact, figurative language abounds as jargon in the field of play or in discussions about the merits of the game afterwards. Even people who know very little about baseball are familiar with terms such as "slugger, strikeout and home run" and do not question their meaning. In The Art of Fielding by Chad Harbach, the team captain (Mike) and his protege (Henry), the underdog, predictably rise to the occasion and save the day, despite readers beginning to question whether they could ever recover from a lack of confidence, poor choices, bad decisions and failing egos.
Westish College, "that little school in the crook of the baseball glove that is Wisconsin,"(ch 1) is the focus of the story and the comparison of the Wisconsin to the "crook..."is one of many metaphors used to help the reader visualize. Guert Affenlight is Westish College's president, a learned man who becomes obsessed with Owen, a student and Henry's room-mate. He watches practice from the bleachers:
His forearms, hands and thighs formed a diamond-shaped pond into which his tie dropped like an ice fisher’s line.(ch 8)
There is both a metaphor as Guert's thighs, etc form a "diamond- shaped pond" and a simile as Guert's tie is compared to the line of an ice fisherman.
