Petco Park is an open-air ballpark in downtown San Diego, California, USA. It opened in 2004, replacing Jack Murphy/Qualcomm Stadium as the home park of Major League Baseball’s San Diego Padres. The Padres previously shared Jack Murphy/Qualcomm Stadium with The National Football League’s San Diego Chargers. Petco Park is named after the pet supplies retailer Petco, which is based in San Diego and paid for the naming rights.
The ballpark is located between 7th and 10th avenues, South of J Street. The southern side of the stadium is bounded by San Diego Trolley light rail tracks along the north side of Harbor Drive (which serve the adjacent San Diego Convention Center). The portion of K Street between 7th and 10th is now closed to automobiles and serves as a pedestrian promenade along the back of the left and center field outfield seating (and also provides access to the "Park At The Park" behind center field). Two of the stadium’s outfield entrance areas are located at K Street’s intersections with 7th and 10th Avenues. The main entrance, behind home plate, is at the south end of Park Boulevard (at Imperial) and faces the San Diego Trolley station 12th & Imperial Transit Center.
