One of two Robertson brothers to be inducted into the Napa High School Athletic Hall of Fame, older brother Bill was a baseball and basketball star for the Indians in the late 1950s. In basketball, as a junior in 1957-58, the six-foot, four-inch Robertson led Napa High in scoring and was selected as the Most Valuable Player in the Drake Tournament in which Napa lost to the host in the finals of the tournament. As a senior, Robertson continued his fine play and again led Napa in scoring and rebounding and was selected to the All-NBL team with teammate and fellow Hall of Famer, John Rawlins. Robertson also excelled in baseball at Napa High, both as a pitcher and first baseman. As a junior, in addition to being the leading pitcher for the Napa nine, Robertson hit .411 to lead all hitters. As a senior, Robertson excelled on the mound for the Indians. His pitching successes included a one-hit shutout against Montgomery of Santa Rosa and a 17-strikeout no-hitter against San Rafael in the same year. He continued to play first base when not pitching and he earned All-NBL and All-North Coast honors for his season efforts. Robertson’s successes on the basketball court and baseball field while at Napa High earned him an athletic scholarship to San Jose State but a shoulder injury in his freshman year marked the end of Robertson’s college baseball career. However, he had a successful career as a member of the Spartan’s freshman and varsity basketball teams.
