As baseball bows in, so does SI's special issue. In a hymn to the hot corner, Jim Kaplan salutes Mike Schmidt of Philadelphia and George Brett of Kansas City—MVPs and World Series heroes. Steve Wulf profiles Atlanta's Bob Horner, a third baseman making a fast trip to the top, and describes the tricks of the trade that give players an extra, though not always legal, advantage. Ron Fimrite examines the most beleaguered soul in any league, the manager. Scouting reports on teams in all four divisions complete the lineup. Plus all the week's news and our regular features.
