Barraclough was optioned to Triple-A New Orleans on Tuesday.
Barraclough was seen as a possibility to earn a spot in the back end of Miami's bullpen for the start of the season, but he struggled in the spring to the tune of a 4.26 ERA with as many walks (eight) as strikeouts. The move down to the minors still comes as a bit of a surprise, but the 25-year-old should work his way into the major league mix at some point.
