It's fairly easy to give the Cardinals the advantage at this position, since Albert Pujols is the best hitter of his generation. With Sean Casey healthy again, the advantage is even greater, since Casey hits like a shortstop. However, it looks like Leyland plans on putting Casey at designated hitter during the games in Detroit, which puts Guillen at first. Guillen matches up much better with Pujols, since he's a shortstop that hits like a first baseman. Still, even with a bad hamstring, it's tough not to go with Albert at this position.
