league attendance record, drawing 670,000 fans. This showcased the feasibility that San Francisco could someday sustain and support a Major League franchise and Fagan was posturing to position the Seals to become a major league franchise. In 1950, Fagan briefly halted peanut sales at the stadium, possibly due to cleanup costs. The move was ill-advised, as disgruntled fans brought their own peanuts and hurled the shells onto the field. After the “Peanut Revolt,” Fagan gave away 18,000 free bags of peanuts. In 1958, after the New York Giants announced their intention move to San Francisco, the Seals were forced to move. The minor league franchise was relocated to Phoenix, Arizona in 1958, becoming the Phoenix Giants. San Francisco Giants (1958–1959) On May 28, 1957, the New York Giants and owner Horace Stoneham announced they intended to leave the Polo Grounds in New York City and relocate to San Francisco. The major league owners approved the move under the condition that the Brooklyn Dodgers would also complete their intended move to Los Angeles. Dodgers' owner Walter O'Malley and San Francisco Mayor George Christopher had worked to partner with Stoneham on the move to San Francisco. Both teams moving to California together made sense for scheduling balance and travel. On August 19, 1957, official announcement of the moves was made. By agreement, both teams would play in temporary locations while each city build a new ballpark. The Giants agreed to play at Seals Stadium while Candlestick Park was under construction and the Dodgers played at Los Angeles Memorial Coliseum, (bypassing smaller Los Angeles Wrigley Field), while Dodger Stadium was under construction. To accommodate Major League Baseball, more seating was needed at Seals Stadium. A separate uncovered bleacher section was added in left field. The ballfield remained without a warning track. Given the temporary usage by the Giants, Seals Stadium was not renamed. The original plan was to play just the first year at Seals Stadium, but that proved to not be the case. On April 15, 1958, the first West Coast Major League game was played at Seals Park. With Hall of Famers Willie Mays and Orlando Cepeda, the Giants opened with an 8–0 victory over Don Drysdale and the new Los Angeles Dodgers. Mays would go on to hit .347 with 29 home runs in 1958 and Cepeda would win the National League Rookie of the Year Award. Willie McCovey, another
