The Marlins announced that they have designated left-hander Grant Dayton for assignment. The move frees up a 40-man roster spot for catcher Jhonatan Solano, whose contract was selected today when Jarrod Saltalamacchia was placed on the paternity list.
The 27-year-old Dayton was Miami’s 11th-round pick back in 2010 out of Auburn University. Baseball America ranked him among Miami’s Top 30 prospects prior to each of the 2012-14 seasons, ranging from 17th to 25th. Dayton has worked almost exclusively as a reliever over the course of his Minor League career, totaling a 2.63 ERA with 10.9 K/9 and 3.2 BB/9 in 263 innings of work. He’s typically been old for his level, however, and didn’t reach Triple-A until his age-26 season in 2014.
