Great Trivia Question - Jack Maguire was the last player to wear #24 for the Giants before Willie Mays. At the time Mays was called up to the Giants Maguire was still on the roster wearing #24, so Mays was given #14. When Maguire was acquired by the Pirates, Mays took #24, and no other Giant has worn it since.
