Aardsma decided to opt out of his minor-league contract with the Dodgers on Thursday and will become a free agent, MLB Trade Rumors reports. Aardsma had a 72-hour window around the June 1 opt-out clause in his contract, and elected to exercise it when the Dodgers failed to add him to their 25-man roster. The 33-year-old shouldn't have trouble latching on with another organization after posting a 2.41 ERA and 11.1 K/9 rate over 18.2 innings while serving as the closer for Triple-A Albuquerque.
