The Marlins claimed right-hander Sam Dyson off of waivers from the Blue Jays, Joe Capozzi of the Palm Beach Post reports (on Twitter). The Marlins designated center fielder Kevin Mattison for assignment in a related move.
The Blue Jays designated Dyson for assignment last week to create roster space for Mark DeRosa. The 24-year-old made his MLB debut this past season, appearing in two games at the big league level. He spent most of the season in the minor leagues, posting a 3.04 ERA with 4.6 K/9 and 2.4 BB/9 in 74 innings at Class A and Double-A.
Mattison also made his MLB debut in 2012. He appeared in three games last May, but spent most of the season at Triple-A. The 27-year-old posted a .241/.310/.394 batting line with 13 home runs in 539 plate appearances at New Orleans.
