Having grown up in Miami, Alex Rodriguez is very proud of the new $515 million Marlins Park. The Yankees third baseman was in the lineup Sunday for the first game between two big-league clubs at the new stadium. "I don't want to be corny or cheesy because it is a spring training game and all that, but for me this is a very special day," he said. "To be able to grow up in these streets, in these square blocks ... I never imagined, as a child, that such a beautiful stadium would be built in the middle of Miami. So I'm very proud of the city of Miami and the Marlins to be able to achieve this in my hometown. "This is kind of like, 'Hello, Major League Baseball. We're here,'" Rodriguez said.
