Rzepczynski is projected to make $3 mil in arbitration, and wasn't that good against LHB last season (.255/.321/.340). He's better than Duensing, but having him on the roster presents the same issues as having Duensing, Fien, Boyer, Cotts, Thornton, etc. -- you're locking in mediocrity to fill a less important role, when you really need to add another quality arm capable of filling a more important role if needed (i.e. Jepsen, Sipp, Bastardo, etc.).
