Garcia was added to the Marlins' 40-man roster on Friday, MLB.com's Joe Frisaro reports.
He is probably a top-10 prospect in the Marlins system, but that is only because it is such a bad system. Garcia posted a 4.91 ERA while striking out 35 over 36.2 innings (seven starts) at Double-A last year, and it's possible that he ends up pitching out of the bullpen long term.
