Top Secret: Mysterious baseball diamond spotted at Area 51

As the growing popularity of the WBC shows, baseball is truly an international game. But according to this Google Maps snapshot of Area 51, the sport may also have an otherworldly following.

The Las Vegas Sun reported  back in 2008 that the diamond at Groom Dry Lake once hosted recreational softball games for a nearby electrical and engineering company. But that was in 1965, and the company has long since moved out.

The Las Vegas 51s borrow their nickname from the military installation, which is officially known as the Air Force Nevada Test and Training Range Complex, but the Mets' Triple-A affiliate plays its home games at Cashman Field -- more than two hours from the mysterious diamond.  So, the questions is, who - or what - plays there now?
