PHILADELPHIA - The Phillies have declined a $6 million club option on pitcher Mike Adams.

Philadelphia made the move Thursday, allowing the relief pitcher to become a free agent. Adams had a 2.89 ERA in 22 games with the Phillies last season, with 21 strikeouts over 18 2-3 innings.

Adams earned $5 million in 2013 and $7 million in 2014. The 2015 option would have been guaranteed at $6 million had he pitched in 65 games this year. It would have been $6.5 million had he pitched 120 games combined in 2013 and 2014 with 60 games in 2014.

Adams has a career ERA of 2.41 across 10 seasons with four clubs, including stints with Texas, San Diego and Milwaukee.
