Blanton, 33, had a 6.04 ERA (62 ERA+) in 132 2/3 innings for the Halos last season, good for -2.0 WAR. He lost a ton of weight over the winter but still allowed 16 runs in 20 1/3 Cactus League innings.
The Angels signed Blanton to a two-year, $15 million contract last winter. They are still on the hook for his $7.5 million salary in 2014, less the pro-rated portion of the league minimum if another team signs him.
Despite his awful 2013 season, Blanton has a track record and another team will likely give him a chance as a depth arm, especially since he'll only cost the league minimum.
