Petco Park opened on April 8, 2004, in the East Village neighborhood of downtown San Diego, California, as the new home of the San Diego Padres. Built at a cost of approximately $449 million, the ballpark replaced San Diego Stadium, which the Padres had called home since the franchise’s MLB debut in 1969. The Padres christened the park in style, defeating the San Francisco Giants 4–3 in 10 innings in the inaugural regular-season game.
Designed by HOK (now Populous) and architect Antoine Predock, Petco Park is celebrated for its seamless integration with San Diego’s urban landscape. Its most distinctive feature is the Western Metal Supply Co. building, a 1909 brick warehouse whose southeast corner serves as the left-field foul pole, housing team retail, luxury suites, and a rooftop deck. Palm trees, a Southern California color palette, and sweeping views of the downtown skyline cement Petco Park’s reputation as one of the finest ballparks in Major League Baseball.

A Ballpark Built Into the Neighborhood
When the East Village district was chosen as the site for the Padres’ new home, the neighborhood was largely industrial and underdeveloped. Petco Park’s arrival catalyzed a dramatic transformation of the surrounding blocks, drawing restaurants, hotels, and residential development to what became one of San Diego’s most vibrant urban quarters. The park’s open concourses offer sightlines to the city skyline, and the ‘Park at the Park’—a public grass berm beyond the center-field wall—invites fans without tickets to soak in the atmosphere outside the gates.
Architects resisted the generic feel of many contemporary stadiums by retaining the Western Metal Supply Co. building’s original 1909 brick exterior and incorporating it structurally into the left-field corner. Rooftop bleachers on the building deliver some of the most unique sightlines in professional baseball, while retractable bleachers in right-center field and a massive HD videoboard installed in 2015 ensure every seat offers an engaging view of the action.

Petco Park quickly established itself on the national stage. It hosted the inaugural 2006 World Baseball Classic championship series, bringing international competition to San Diego’s diamond.

Beyond baseball, the ballpark has served as a multi-sport and entertainment venue, hosting soccer matches, rugby, college football, and major concerts over its two-decade history.
