Thanks to an All-Star ace, a solid bullpen and an abundance of .300 hitters, the Miami Marlins can savor their best record at the All-Star break since 1997. First-year Marlins manager Don Mattingly says his job is to make sure his young team isn't satisfied with what it has accomplished so far. ''That's why they brought me in,'' said Mattingly, who led the Los Angeles Dodgers to division titles in 2013-15.
