There is an excellent chance that late Tuesday night, the San Francisco Giants will find themselves a full 30 games behind the Los Angeles Dodgers. The magic number will be 38, and the Giants chances of catching the Dodgers can be reduced to absolute zero on August 27. It would dovetail with their grudging admission Monday night that they are no longer selling out baseball games routinely, as their announced crowd of tickets sold totaled 39,538, or 2,377 below listed capacity.
