SAN ANTONIO -- Bexar County Judge Nelson Wolff sent a letter Wednesday to Florida Marlins officials detailing a new stadium plan for the Major League Baseball team.

Wolff said the letter tells the Marlins that Bexar County would pay $200 million toward a stadium with an existing hotel-motel tax that is currently paying for the AT& Center.

"The next step would be them coming down here and beginning some very intense negotiations to see if there is a way to reach an agreement," Wolff said.

Wolff said the Marlins will need to come up with about $100 million to make the deal work. The letter also states that local ownership will be mandatory.

Car dealership magnate Red McCombs, who used to own the Spurs, the Denver Nuggets and the Minnesota Vikings, said he is interested in investing in the team.

Also interested in possible ownership is the family of former Houston Astros and Texas Rangers great Nolan Ryan, who owns a portion of the minor league team Round Rock Express. His son, Reid Ryan, also owns the minor league team Corpus Christi Hooks.

Eventually, voters in Bexar County would have the final say in the proposal, Wolff said.

"This is a once in a lifetime chance to bring Major League Baseball to San Antonio," he added.
