The Dodgers anticipated a financial windfall by moving their preseason home from Vero Beach, Fla. to Arizona, thousands of miles closer to the vast majority of their fans and to a sparkling new training complex expected to attract the attention of deep-pocketed corporate sponsorship. The Dodgers, who open camp Saturday, had a goal of selling 4,000 season tickets for spring training but will probably sell about half of that, chief operating officer Dennis Mannion said. And those corporate sponsors? They're staying away too.
