You a baseball fan? If yes, then you know Forbes intends no insult in saying that baseball is boring. “Boredom is potential. Boredom is the basic element of all of baseball’s dramas.” Too true, and quite unlike this fast-paced collection of short hits on the subject of a game the Peterborough, Ont., writer has loved since he was a kid: Forbes’s baseball diamond has 24 essays covering a mere 150 pages. So he moves like the blazes. He begins with “Sanctuary,” likening the stadium to a house of worship. He ends with “162,” the end of the season, when 10 teams vie for the championship. In between, he immerses the reader in virtually every lackadaisical thought to which baseball lends itself.
