Jay Hook began his career in Cincinnati before joining the expansion Mets. In 1962 Hook lost 19 games which wasn't even good (or bad) enough to lead the team! Roger Craig lost 24 games that year. Hook spent 3 seasons in New York going 12-34 with a 5.22 ERA.
John DeMerit's first season with the Mets was his last season in MLB. DeMerit had three hits in 1962 - one of them a home run.
