Horst was released by the Dodgers on Wednesday, Eric Stephen of True Blue LA reports. Horst pitched well with Double-A Tulsa this season, posting a 1.64 ERA and 1.52 WHIP with 42 strikeouts over 38.1 innings. He did struggle with his command, however, allowing 20 walks over the same amount of frames. He's now a free agent, and will be free to look for work elsewhere.
