The Detroit Tigers are undefeated. Please, people, let me gloat for one day. It’s been a long decade or so–you will recall that the Tigers lost their first 11 games last year–and this probably will become another long season. Still, it’s April; a time for hope. The Tigers beat the reigning Cy Young champ in Toronto yesterday, 7-0. There’s also a new book that every suffering Tigers fan deserves to own: ’84: The Last of the Great Tigers, by Eli Zaret.
