News: Camp has signed a major league deal with the Mariners, the club's official Twitter feed reports.
Impact: Camp should form a piece of the back end of the Mariners' bullpen. He's coming off a poor 2011 in which he posted a 4.21 ERA and just a 32:22 K:BB ratio. However, 2009 and 2010 each saw sub-3.50 ERAs and K:BB ratios of 2.0 or better, so there is some hope for improvement, particularly in a pitchers' park like Safeco Field.

News: Gimenez has been designated for assignment to make room on the 40-man roster for Shawn Camp, the Mariners' official Twitter account reports.
Impact: Gimenez has been bouncing around lately, first being non-tendered and then signing a contract with the Mariners and now tumbling off the 40-man roster again. Gimenez hit just .203/.314/.271 and may just have to settle for a chance to win a job in spring training.

News: The Mariners signed Kuo to a one-year deal.
Impact: 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.

News: Camp signed a one-year contract with Toronto.
Impact: 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.

News: Kuo (elbow) has signed a one-year deal with the Mariners, Dylan Hernandez of the L.A. Times reports.
Impact: When he is right, Kuo can be dominating, but he is bouncing back from his fifth elbow operation, and his work was limited in 2011 by an anxiety disorder, so he's no sure thing. Assuming his health and improved command -- he had a 36:26 K:BB ratio in 27 innings last year -- he'll open the season in the Mariners' setup mix behind closer Brandon League.

News: Guillen signed a minor league deal with Seattle on Wednesday including an invitation to spring training, the Mariners' official Twitter feed reports.
Impact: Injuries limited him to just 95 at-bats in Detroit last season, so Guillen will be in camp battling for a reserve role with the Mariners and trying to prove that he's healthy. His best chance for making the team, though, is if the Mariners find a taker for Chone Figgins. Otherwise, there's little available room on the roster.

News: Guillen is returning to Seattle after agreeing to a minor league contract with the Mariners. Seattle announced the deal on Wednesday.
Impact: The 36-year-old spent the past eight seasons in Detroit where he was a three-time All-Star and hit .308 in his career with the Tigers playing five positions: left field, third base, shortstop, second base and first base. Guillen started his career with the Mariners from 1998-03, playing in 488 games in Seattle. Guillen is likely to compete for a reserve utility role with the Mariners.
