With 14 wins in 17 games, the Royals have pulled within four games of the second AL wild-card berth. The key to their success: "The bullpen hasn't given up a run in who knows how long," Red Sox manager John Farrell said. "It's been nearly 40 innings." Boston, on the other hand, has lost eight of its last 13 one-run games largely because it lacks defined bullpen roles other than closer Craig Kimbrel. Should be an interesting three-game series at Fenway.
