THE OAKLAND ATHLETICS and Seattle Mariners are playing a baseball game on a Tuesday night in Oakland, and it's difficult to describe the silence. There are maybe 1,000 people in the stands at first pitch, and few of them have the energy or the inclination to make any noise. The team is the worst in baseball and the stadium is the worst facility in professional sports and the owner is two weeks removed from signing a land deal -- one he will cancel before signing another -- that he hopes will take the team to Las Vegas.
