 Biographical Information
Second baseman Jeff Cox signed his first pro contract with the Kansas City Royals in August 1973 but was released by the team in early 1974 after the attending the Royals Baseball Academy but before playing in a game. He was signed by the New Westminster Frasers in June of 1974 and sold to the Portland Mavericks two weeks later. Portland released him in June of 1975 and he signed with the Oakland Athletics three days later. In 1977, he was a Southern League All-Star with the Chattanooga Lookouts and led the circuit with 68 stolen bases.
Cox reached the majors with the A's on July 1, 1980 and got his first big league hit off Lary Sorensen of the Milwaukee Brewers the next day. He went 9-for-18 in his first 5 major league games, but he hit under .200 from there onwards, ending the season with a .213 mark. He earned a second cup of coffee in the bigs with Oakland the following year, appearing in one game at second base and another as a pinch runner, but did not make a plate appearance that season.
Cox later played in the Detroit Tigers and Kansas City Royals systems and spent time as a player/coach in the Cincinnati Reds organization with the Vermont Reds in 1984. After spending the next season on the Vermont coaching staff, he began his managerial career in 1986 with the Billings Mustangs. Overall, in 13 seasons as a minor league manager, he posted a 736-863 mark.
