During Blake's hitting streak it's become apparent to me that Casey can maintain an OBP of at least .350. Because of this, I would move Casey to the lead off spot and bat Grady second.

Whenever Casey gets on base, either the other team holds Casey at first, which leaves a huge hole on the right side for Grady, or Casey gets a big lead if the other team chooses not hold Casey on. Since Casey is our best baserunner at taking out the second baseman on force plays, it's a win win either way since with a bigger lead Casey may actually beat the throw to second base that aren't hit directly to an infielder.

I think Casey's 25 game streak is really great and I'd like to see Casey have the best chance to keep it going while creating better hitting chances for Grady, which in turn helps Travis and Vic as well. It's a win all the way around.
