I don't think a backend starter gets you much. We had high hopes for Pivetta going into the season considering his turnaround last year, but that seems to be out the window at this point. Not much meat left on the bone. He's a very low ceiling guy. Martin's skillset is much more valuable to teams that are in contention. Fortunately for the Sox, they are in contention this year so I don't think either will be traded if the Sox continue their current trajectory.
