Commissioner Bud Selig rarely speaks off the cuff. Before hementions a proposal, ordinarily he has decided he wants it. Thus, when Selig suggested last season that he favors expandingthe playoffs with two extra wild-card teams and another round ofgames, Dave Righetti's head must have exploded. As the Giants advanced through thepostseason, one could almost hear the pitch-count clicker go "tilt"inside the pitching coach's head. This team's principal asset is its young rotation, ahigh-performance engine that the Giants had to red-line through 15postseason games to win the World Series.
