The Marlins optioned Maldonado to Triple-A Jacksonville on Sunday.
In a weak and shallow Marlins farm system, Maldonado is one of the few fantasy-relevant prospects, albeit for deeper leagues. He had a 3.75 ERA, 1.25 WHIP, seven strikeouts and one save in 12 innings with the big club. Maldonado threw his mid-80s slider two-thirds of the time and his 93 mile-per-hour fastball just over 30 percent of the time while in the majors.
