Floro was designated for assignment Friday.
The Dodgers needed to clear a spot on the 40-man roster for Curtis Granderson, who was acquired from the Mets for a player to be named later. Floro, who has only been in the Dodgers' organization for a couple weeks, has compiled a 4.42 ERA and 1.38 WHIP across 55 innings in the minors this season, primarily in the Cubs' organization.
