Someone (was it Tragg?) commented on how it was a bad idea to start a rookie in this situation and asked why it was done. According to Gonzo in his post game post mortum Robin made the decision in order to give Peavy an extra day of rest. He goes Thursday against Tampa Bay.
Something else I noticed, this started in Baltimore when the Sox started sliding, it seems like a lot of guys who aren't home run hitters are driving balls out of the park off the staff. Cleveland did that the last two nights.
