I think he was OF, 3B and 2B but no SS when he came to the Yankees. He was at that stage of his career a utility type guy, who once played all 9 positions in a game.

"On September 8, 1965, as part of a special promotion featuring the popular young player, Campaneris became the first player to play every position in a major league game. On the mound, he pitched ambidextrously, throwing lefty to left-handers, and switched against right-handers. Since then, César Tovar (Twins, 1968), Scott Sheldon (Rangers, 2000) and Shane Halter (Tigers, 2000) have joined this select list of nine-position players in a major league game."
