My latest for SportsWorld is on the Royals remarkable bullpen and how — luck or skill — Kansas City happened upon what might be baseball’s new paradigm. I’m not sure how far this will go. But the Royals essentially have three closers with the firm: Kelvin Herrera, Wade Davis and Greg Holland. Will teams keep going in this direction? Is a sixth-inning closer something teams will consider in the future? How about a starter that goes four innings every four days and then five closers?
