Opening day

The Giants and the now-Los Angeles Dodgers, arch-rivals for 68 years in New York, faced each other in their respective first-ever game on the West Coast. On Tuesday afternoon, April 15, 1958, at Seals Stadium, the Giants' temporary home park, San Francisco blanked Los Angeles, 8–0, behind Rubén Gómez' complete game, six-hit shutout. Gómez fanned six, issued no bases on balls, and went two for four at the plate. Daryl Spencer hit the first home run in San Francisco's MLB history with a solo shot in the fourth inning, and rookie Orlando Cepeda followed with another solo blast one inning later. Willie Mays had two runs batted in. Don Drysdale took the loss for the Dodgers. Attendance at the longtime minor league stadium was a sellout, 23,448.
