The Philadelphia Phillies and Chicago White Sox are keeping tabs on Mike Moustakas in the event they are unable to land Manny Machado, according to sources.

Moustakas is represented by Scott Boras, who also represents Bryce Harper. Both clubs have been linked to Harper as well.

Last offseason, Moustakas remained on the open market until re-signing with the Kansas City Royals on a one-year, $6.5 million deal in March.
