Karen Price of the Tribune-Review tweets that the Pirates will miss Jeff Karstens' next start. It's not yet clear who the replacement will be. Personally, I would start Chris Leroux. Neal Huntington, on his radio show yesterday, said it was unlikely that Leroux would be a starter next spring, his preference, because they couldn't stretch out his innings enough and he is out of options next year. Here is the chance. Other options include Aaron Thompson, Garrett Olson, Sean Gallagher, Jeff Locke and Daniel McCutchen. Leroux seems an easy choice.
