Bob Robertson was a big first baseman who could hit for power but often had his way blocked with the Pittsburgh Pirates by such stars as Willie Stargell and Al Oliver. He hit 26 and 27 home runs in 1970 and 1971, respectively before a chronic back problem hampered his production.
Robertson had a very good minor league record. He debuted in 1964 with a .302, 13, 63 line for the Salem Pirates. He led Appalachian League thirdbaseman with 43 PO, 102 A, 7 DP, and 36 E. In 1965, he led the Western Carolinas League with 32 HR, 98 RBI, and 258 TB. He also led WCL 3B with 101 PO, 242 A, and a .932 FP. He led the 1966 Southern League with 32 HR, 99 RBI, 258 TB, 131 PO and 26 E at 3B for the Asheville Tourists. Robertson was converted to first base during the 1967 season. He missed the entire 1968 season after surgery for a kidney obstruction. He returned in 1969 to lead the International League with 34 HR. He was named to the 1966 All-Star team for the Southern League at 3B and the 1969 team for the International League at 1B. His 3-homer game in the 1971 NLCS was the first time a Pirate had hit multiple home runs in a postseason game; it would be 42 years until Russell Martin became the second.
