Busch was optioned Monday to minor-league camp by the Dodgers.
Busch has struggled in his brief Cactus League sample, with a slash line of .150/.320/.300 with one homer in 25 plate appearances. Those struggles have very little to do with why he's opening the season in the minors, however, and the 25-year-old could be an option for the Dodgers at some point this summer as one of the club's best hitting prospects.
