Madison Bumgarner is a throwback to the days before pampering and pitch counts. Tall, with droopy hair and the look of a gunslinger, he strung together a sequence of World Series performances seldom seen since the games were played in daylight, kids in school listened on radios and Sandy Koufax, Bob Gibson and Mickey Lolich dominated. ''I don't know if it'll ever be done again,'' Jeremy Affeldt said after Bumgarner came out of the bullpen with five scoreless innings to lead San Francisco over the Kansas City Royals 3-2 Wednesday for the Giants' third World Series title in five years. In an age when arms are treated like fragile investments and fear of Tommy John surgery fills every clubhouse, Bumgarner just wanted the ball as often as possible.
