Petco Park
Petco Park is an open-air stadium in downtown San Diego, California. It opened in 2004, replacing Qualcomm Stadium as the home park of Major League Baseball's San Diego Padres. Before then, the Padres shared Qualcomm Stadium with the NFL's San Diego Chargers. The stadium is named after the animal and pet supplies retailer PETCO, which is based in San Diego and paid for the naming rights.
