Oaks Park, formally known as the Oakland Baseball Park, and at times nicknamed Emeryville Park, was a baseball stadium in Emeryville, California. It was primarily used for baseball, and was the home field of the Oakland OaksPacific Coast Leaguebaseball team. It opened in 1913 and held 11,000 people. The Oaks played there until 1955. The ballpark was located within the city limits of Emeryville, between Oakland and Berkeley. The site was on the block bounded by 45th Street ; San Pablo Avenue ; Park Avenue ; and Watts Street. The stadium did not front directly on San Pablo where a strip of various small commercial buildings stood, now replaced by a single one-story commercial building with several chain businesses. Oaks Park was highly accessible, as a major streetcar line ran on San Pablo Avenue, and a station serving several of the Key System's transbay commuter rail lines existed a few blocks south at Yerba Buena Avenue. The Oaks had been playing most of their home games at Recreation Park in San Francisco, starting when that new ballpark opened in 1907. Even after moving back to Oakland, the Oaks would play a number of games each year in San Francisco. PCL founding father J. Cal Ewing owned both the Oaks and the San Francisco Seals from 1903 until sometime in the 1920s, at which point the Oaks began playing all their games in Oakland. The park was not well maintained in its later years, causing a steep decline in attendance. These factors forced the Oaks to move to Vancouver in 1956. That move proved prescient, as the New York Giants moved to San Francisco two years later and would have likely displaced the Oaks in any event. Until recently, the site of the park was partly an empty, fenced-off lot, with Pixar Studios overlapping it where Watts Street used to run through. In 2011, it was incorporated into the second phase of Pixar Studios' expansion. It is now a parking lot with a public bicycle path and park on the San Pablo side of the property, across the street from Oaks Card Club.
