THIS! I'd also like to add in that having V-Mart catch is ridiculous. He caught ONE game this season and it was due to Miggy and Avila being injured. He is coming off a serious knee injury and his knees cannot handle catching more than every once in a while.
Edit: Didn't see the edit already mentioning V-Mart.
I think the Tigers have slightly better pitching, but the Red Sox defense, especially at the moment is a lot better. Miggy looks horrible defensively and Peralta wasn't a good SS and is an even worse LF.
