Cashman Field had been suggested as a temporary stadium in the city's efforts to woo either a Major League Baseball expansion team, or an existing team desiring to move. The stadium would have served as home field until a permanent facility could be built. It had come up in the city's talks to lure the former Montreal Expos, Florida Marlins, and Oakland Athletics. However, the park would have needed considerable expansion, particularly in seating capacity, in order to host a team. The substantial costs which would be incurred in expansion and construction of a new stadium, as well as MLB concerns over Las Vegas' legalized gambling, have so far kept the city's proposals from achieving success.
