Mayor Oscar Goodman may be a crazy dreamer, but he’s keeping hope alive of landing a major league baseball team for Las Vegas. At his weekly news conference on Thursday, Goodman said he is still in talks to build a new baseball stadium on city-owned land. The facility would be a dome and seat 45,000 fans, but no detailed financing or cost estimate have been released. The mayor added that the city is talking to American League officials to see if any team would be willing to move here if a new stadium is built, since Las Vegas is designated as an American League city. But Goodman cautioned that any potential deal is a long way off, and may not be completed before he leaves office next spring. The city is also in negotiations with a Baltimore-based developer regarding a potential new basketball/hockey arena on city-owned downtown near the site of the planned new City Hall.
