1975 Topps #409 Bob Robertson
About Bob Robertson
Robert Eugene Robertson was born October 2, 1946, in Frostburg, Maryland, and grew up in nearby Mount Savage, where Pirates broadcaster Bob Prince nicknamed him "The Mount Savage Strongboy" for his raw power. A first baseman who led the minors in home runs three times, Robertson debuted with Pittsburgh in 1967, missed all of 1968 with a kidney obstruction, and broke into the regular lineup in 1970, hitting .287 with career highs of 27 homers and 82 RBI as the Pirates won the NL East. In the 1971 postseason he became just the second player to homer three times in one playoff game, finishing with four in the NLCS against San Francisco — a total that still shares the record — then added two more as Pittsburgh beat Baltimore in the World Series. Knee surgeries in 1974 reduced him to part-time duty before he closed out his career with Seattle and Toronto, retiring in 1979 with 115 home runs. His 1975 Topps card shows him still at first base for the Pirates.
