Kam's career can be divided into two categories: before he went to Japan in 2009 (and, no, we're not going to abbreviate that time period as "BJ," you deviants) and after he came back to the States in 2010. Before he went to Japan, Kam appeared in 137 games for the Rangers, making 47 starts. He wasn't good as a starter -- he made 15 starts in 2006 and 23 in 2007, and posted ERAs of 5.86 and 5.36, respectively -- but he was OK as a reliever. When he came back from Japan, Kam found his niche: he had a 2.78 ERA in 53 appearances for the Crew in 2010, and he was at 3.50 in 72 appearances last year. Over the last two-and-a-half seasons, he's been worth 1.5 fWAR (and that's including this year's 0.0 mark through 37 games).
How desperate should we be to move him, on the Rubie Q Patented Trade This Slug-O-Meter: If I had my druthers, I'd hang on to Big Kam and part ways with Veras and Parra (and maybe Axford???? TEASE!). As such, I give this one a 3.
