As one park goes down, another goes up:
After more than a decade of negotiating and waiting, a date to begin construction on the Marlins’ new retractable-roof ballpark has been set . . . the ceremonial groundbreaking will take place on July 18, the Saturday after the All-Star break . . . Technically, workers will be on the Orange Bowl grounds to start building on July 1. The first few weeks, however, will be devoted to preparing the area for building. The July 18 ceremony will take place hours before the Marlins face the Phillies that night at Land Shark Stadium, the club’s home until the new park is ready.
