The Mariners announced that four players from last season have officially become free agents - Catcher Miguel Olivo, and pitchers Oliver Perez, George Sherrill and Kevin Millwood.
One player that was expected to become a free agent is right-hander pitcher Hisashi Iwakuma. However, according to the Mariners, Iwakuma has until Saturday to negotiate a deal with the Mariners before becoming a free agent. It seems likely that a deal with Iwakuma, who likes the organization, will get done.
Millwood, 37, went 6-12 with one shutout and a 4.25 ERA in 28 starts. The 16-year Major League veteran made his last start of the season Sept. 12 at Toronto, and did not pitch the rest of the season with right shoulder soreness. He ranked T4th in the AL with 10 no-decisions and had the 4th-lowest run support average by an AL starter (3.75 RSA).
Olivo, 34, appeared in 87 games in 2012, starting a team-high 68 games at catcher. He hit .222 (70x315) with 12 home runs and 29 RBI, his seventh consecutive season with double-digits in home runs. Behind the plate he ranked tied for 4th in the American League with 19 caught stealing.
Perez, 31, posted a 2.12 ERA (7 ER, 29.2 IP) in 33 appearances. After spending most of his career as a starting pitcher, Perez made the conversion to the bullpen where he posted the 9th-best ERA by an AL reliever (min. 30 G).
Sherrill, 35, spent nearly the entire 2012 season on the disabled list with a left elbow injury. He made two appearances (0-0, 27.00 ERA) before going on the disabled list April 13 (retro to 4/10). He had season-ending Tommy John surgery on his left elbow on May 4.
