The Marlins are now officially on the clock. Bexar County Judge Nelson Wolff on Monday set a May 15 deadline for the team to respond to San Antonio's offer to help finance a stadium. Major League Baseball will have significant input in the Marlins' decision and also plans to increase its involvement in stadium negotiations locally, industry officials said. The Marlins declined to comment. Asked what will happen if the Marlins don't say yes by May 15, Wolff told The San Antonio Express News, ``As far as I'm concerned, it's over. . . . I've been in business for a long time and have sold two companies. I know this game a little. ``They need to see if they can get [a stadium deal] in Miami, and this sets a time frame for them to do that. It puts pressure on the Marlins and Major League Baseball.''
