Jerome Martin Koosman was a Major League Baseball player with the New York Mets (1967-1978), Minnesota Twins (1979-1981), Chicago White Sox (1981-1983), and Philadelphia Phillies (1984-1985). Jerry, his nickname, did not win the Rookie of the Year Award in 1968, but he did win nineteen games that year, breaking the New York Mets' record for most wins in a season by a rookie pitcher (a mark that still stands, through today), set previously by Tom Seaver, who won sixteen games in 1967.
