What about left handed pitchers? Not a huge difference and it should be noted that the Rox faced 100 righties last year (and thus 62 lefties).
I don't envy Tracy and his matching up. My guess is he will find the hot lineup and go with it. Day games will have Helton taking the day and my guess is if Helton gets off to a rough start he will find himself riding the bench because this team is built for the now. They can't afford to be kind to the old guard...they have too much riding on the now!
