Rodney was designated for assignment by the Mariners last week, giving the team 10 days to trade or release him.
Rodney pitched 50 2/3 innings for the Mariners this season and had a 5.68 ERA. He blew six of his 22 save opportunities and posted a 1.50 WHIP, his worst since 2011. He led the majors with 48 saves last season.
Rodney, 38, is the final year of his contract.
