From the Associated Press:
The Mariners have agreed to one-year contracts with pitchers Shawn Camp and Hong-Chih Kuo in an attempt to add bullpen depth.
Kuo was an All-Star in 2010 with the Dodgers but struggled last season with a back problem early in the season and missed a month with anxiety disorder. During his standout 2010 season, Kuo as 3-2 with 12 saves in 13 chances and a 1.20 ERA.
Camp led Toronto with 67 appearances last year and was 6-3 with a 4.21 ERA. The right-hander has appeared in 432 games all in relief, with Kansas City, Tampa Bay and Toronto.

To clear space on the 40-man roster, Seattle designated outfielder Mike Wilson and catcher Chris Gimenez for assignment.
