Mets LHP Josh Edgin has elected to become a free agent after New York designated him for assignment and he cleared waivers earlier this season, according to Metsmerized's Michael Mayer.
Edgin, 30, was outrighted to Triple-A as Vegas in August to make room on the 40- and 25-man rosters for AJ Ramos.
The Mets' 30th-round pick in 2010, Edgin underwent arthroscopic surgery on his knee in September. He went 0-1 with a 3.65 ERA in 46 relief appearances for New York this season, striking out 27 batters and walking 18 in 37 innings.
