It’s time to get nervous.
        The Tigers and their fans have invested too much effort and emotion into this strange season to see it all slip away now.
        The Tigers’ magic number is down to six, thanks to Kansas City’s 4-1 win over the Minnesota Twins on Sunday, and the lead they have enjoyed in the American League Central since May 10 remains at two games.
        Here are the possibilities -- and their consequences:
        If the Tigers take three out of four from the Twins this week, the suspense will be over. The Tigers clinch.
        If the Tigers and Twins split their four games, the Tigers’ magic number will be reduced to two and they will continue to lead by two games with three to play next weekend against the Chicago White Sox while the Twins host Kansas City.
        If the Twins take three out of four from the Tigers, the two teams will be tied and it will all be on the line next weekend -- and a possible tie to be settled by sudden-death playoff in Minnesota next Monday will suddenly become a worrisome possibility.
        If the Twins sweep the Tigers, their roles will be reversed and the Tigers will trail the rampaging Twins by two games with three to play.
