5. Chris Stratton
Although it might be hard to say goodbye to Montgomery if he leaves, the same can't be said for Chris Stratton.
The 33-year-old reliever, who also came over in the aforementioned deal with the Cardinals, has left much to be desired. Although he played well initially, Stratton is now up to a dismal 7.50 ERA in his last 12 relief appearances. That includes giving up three earned runs on as many hits over 3 1/3 playoff innings — good for an 8.10 ERA during that span.
After his playoff debacle, I can't think of a good reason to bring Stratton back. He's a streaky reliever whose lows are pretty, well, low. It's tough to feel comfortable when he takes to the mound in a playoff game, especially if the score is close.
Fortunately, Stratton's free-agent status this winter makes ditching him easy. Let him try to get back on track on someone else's time (and dollar).
