I figured out how to pitch, I think. Only gave up 1 run in 3 innings. Can't for the life of me figure out how to hit. The only base hit I had was a bunt, and that was by accident pushing buttons.
Otherwise, the game does own the 2k series in graphics and pretty much everything else from what I can see. I just wish you had to use the sticks (or had the option) to hit/pitch. Maybe it'll be in MLB '10: The Show.
