Officially called Angel Stadium of Anaheim, this ballpark was constructed in 1966. It has been home to the Los Angeles metro's American League franchise, the Angels, since it first opened. In 1967, the first prime-time, televised All Star Game was played here. The stadium is nicknamed the Big A because of a towering Angels' logo, a halo-topped A, that stands in one of the parking lots outside of the stadium. The park's original dimensions were the result of an extensive scientific study that was aimed at making a playing area that was equally advantageous to both hitters and pitchers. The Big A was used by the NFL's Los Angeles Rams franchise during their stay in California, but was renovated into a baseball-only stadium after the football team moved to St. Louis.
