Step 1: Study [url=http://strato.berce.us/dice.htm]THIS CHART[/url] everyday until memorized.
Zambrano has 2 HR chances out of 104, and [b:3498d1dbfe]4[/b:3498d1dbfe] (!) BP chances out of 104 vs RHBs. It doesn't matter really where they are on a card, although it is helpful to know the percenatages when glancing at cards. One BP chance on the 2 roll at 2.78%/3 columns, is no problem. If you add another on say the 11 (5.56/3 columns), we are now starting to have problems, especially if you have hitters' parks in your divsion.
That's why Zambrano must be watched in hitters' parks against teams with some LH pop.
