In 2011, Lueke, a right-handed relief pitcher, split the season between triple-A and the majors. With Seattle, Lueke had a 6.06 ERA in 32.2 innings with 29 strikeouts and 13 walks. His 3.24 FIP indicates that he pitched much better than his ERA suggests.
Jaso struggled both offensively (.224 with 5 home runs) and defensively in 2011. He and Jose Lobaton are both out of minor league options. And with the Rays expected to sign Jose Molina, somebody had to be traded.
