Mariners designated LHP Mauricio Robles for assignment.
The move was made in order to clear space on the 40-man roster for recently-signed outfielder Jason Bay. Robles struggled mightily with his control in 2012, issuing 63 walks over 71 2/3 minor league innings. Should he clear waivers, he'll continue to serve as bullpen depth at Triple-A Tacoma.
