Anderson was called up by the Marlins on Friday, and will be starting at third base against the Phillies, Joe Frisaro of MLB.com reports.
Anderson will make his major-league debut at third base, just a month and a half since earning a promotion to Triple-A Jacksonville. During his time with the Triple-A club, Anderson slashed .339/.416/.602 with eight home runs and 26 RBI. The 24-year-old is one of the top prospects in the Marlins system, and looks to get a decent amount of playing time over the next month with Miami.
