Can defense keep AL Central close?

Can Lorenzo Cain stay healthy enough to help provide the Royals with the kind of elite defense that helped deliver pennants in 2014 and 2015? Rick Scuteri/USA TODAY Sports

In the National League Central, most of the Chicago Cubs' core is young and in its prime. In the American League Central, the Cleveland Indians were expecting to be healthier and had added Edwin Encarnacion to solidify the middle of their lineup. But both of those teams are sitting around .500, with several surprise teams keeping pace early.
