1975 Topps #483 Steve Ontiveros
About Steve Ontiveros
Steve Ontiveros broke into pro ball as a switch-hitting third baseman out of Bakersfield, California, taken by the San Francisco Giants in the sixth round of the 1969 draft. He won The Sporting News' Minor League Player of the Year award in 1973 before debuting with the Giants that August. His 1975 Topps card, #483, catches him mid-way through a four-year run at third for San Francisco, where he hit .289 in 108 games that season. Traded to the Chicago Cubs in February 1977 in the deal that sent Bill Madlock to San Francisco, Ontiveros had his best season that year: .299 with 10 homers and 68 RBI. He finished his eight-year majors career in 1980, then played six seasons for the Seibu Lions in Japan, batting .312 with 82 home runs.
