A random speculation
After thinking about the rotation that was announced yesterday by the team, the one that goes Perez, blank, Duke, Snell, Maholm. The more I think about it, the more I think that it means someone from outside the organization is filling that blank. I know you could argue that it's all about shuffling guys to get certain people to make starts in that first home series, but I think that goes even beyond what the Pirates would do to put people in the stands. It just doesn't make sense to fill the #2 slot in your rotation with Brandon Duckworth or Victor Santos. Add that in with Craig Wilson recently publicly voicing his displeasure with his treatment by the team, the fact that five teams seem to be interested in him, especially the Braves, and, well, John Thomson anyone?
