How deeply might Kansas City be harmed by free agent losses? Moustakas is the third Royal in the top seven—and he just set a franchise record for home runs. He impressively bounced back from a torn ACL that ruined his 2016, but he'll almost certainly be moving on—perhaps to the Angels, who need an upgrade at third over the .199-hitting Luis Valbuena.
