Goldberg was optioned to Triple-A Charlotte on Wednesday.
The 27-year-old flew up the organizational ladder last season, and despite the strong showing during spring training and an appearance in the World Baseball Classic for Team Israel, Goldberg will head back to the minors for more seasoning. The right-hander's stuff alone isn't all that impressive, but he still manages to get batters out fairly consistently, which could land him a job in the Windy City if he keeps it up at Charlotte.
