Kinsler has great numbers, for a DH. Unfortunately he plays second base. His hands of stone and 15 errors should keep him off the team. Pedroia should start, backed up by Roberts.
I don't see much of the AL, so I'm not too up on their relative defensive prowess. But Kinsler's offensive numbers are clearly the best among AL second-sackers. Pedroia would not be a bad choice, though.
