Marinaccio elected free agency Wednesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.
Rather than accepting an outrighted assignment to Triple-A Louisville after losing his spot on the Reds' 40-man roster and clearing waivers, Marinaccio will explore his options on the open market. Across big-league stops with the Padres, Pirates and Reds this season, Marinaccio has compiled a 6.09 ERA and 1.53 WHIP over 57.2 innings out of the bullpen.
