SEATTLE -- Looking to further bolster their bullpen, the Mariners signed veteran free-agent relievers Shawn Camp and Hong-Chih Kuo to non-guaranteed one-year Major League contracts on Monday.
To make room on the 40-man roster, the Mariners designated outfielder Mike Wilson and catcher Chris Gimenez for assignment and will now have 10 days to trade, release or outright their contracts.
Kuo, a 30-year-old lefty from Taiwan, was a 2010 All-Star for the Dodgers and posted a 3.73 ERA over seven seasons in Los Angeles, but was released after elbow problems and an "anxiety" issue left him with a 9.00 ERA in 40 appearances last season.
When healthy, Kuo was one of the Majors' top relievers with a 1.96 ERA in three seasons from 2008-10, when he allowed 110 hits with 201 strikeouts and 52 walks over 170 innings. The 6-foot-2, 240-pounder had a 1.20 ERA with 12 saves in 2010, when his ERA was the 11th lowest by a reliever in Major League history (minimum 60 innings pitched) and his .139 opponents' batting average was the fifth lowest in MLB history.
The right-handed Camp, 36, appeared in a team-high 67 games for the Blue Jays last year while posting a 6-3 record with a 4.21 ERA and one save in 66 1/3 innings.
Camp has pitched in 196 games in relief over the past three years, third-most in the American League in that span behind only the D-backs' Craig Breslow (219 while with Oakland) and the Mariners' Brandon League (202 with Toronto and Seattle).
Camp has pitched 432 games -- all out of the bullpen -- in eight Major League seasons with the Royals (2004-05), Rays (2006-07) and Blue Jays (2008-11). His career record is 25-26 with a 4.40 ERA and 10 saves and he went 15-13 with a 3.63 ERA over the past four seasons in Toronto.
