Yesterday, the baseball world learned of the passing of Jerry Koosman, a member of both the 1969 World Champion and 1973 National League Champion New York Mets, at 83 year old. Koosman, a member of the Mets Hall of Fame and whose number 36 is retired by the Mets, is one of the most identifiable Mets from their first golden era.
Born in Appleton, Minnesota, the left-hander was discovered while in the military, and the Mets signed him one his service was over. He made his big league debut in 1967, but joined
the Mets full time in 1968, going 19-12 with a 2.08 ERA and 178 strikeouts in 263.2 innings. Koosman finished second to Johnny Bench in the Rookie of the Year voting.
In 1969, Koosman had another fantastic season, and won two games in the ‘69 World Series, pitching 17 and two-thirds innings over two games, and was awarded the ball Cleon Jones caught for the final out of the game.
Koosman continued to be the Mets’ number two starter behind Tom Seaver, and he had a number of very good seasons as Met, including winning 21 games in 1976 and coming in second in the Cy Young voting in 1976. After the Mets’ terrible 1978 season, Koosman requested a trade and was traded to the Twins in exchange for Greg Field and, as a player to be named later, fellow Mets legend Jesse Orosco.
Over his 12 year Mets career, Koosman put up a 3.07, with a 140-137 record. He was an All-Star in 1968 and 1969.
After a fantastic year in 1979 for the Twins, Koosman’s career never quite hit those high marks again. After two and a half seasons with the Twins, two and a half for the White Sox, and two for the Phillies, Koosman retured after the 1985 season. He ended his career with 53.6 bWAR.
Koosman has the third most pitching wins in Mets history (140), behind teammate Seaver and Dwight Gooden. The Mets inducted him into their Hall of Fame in 1989 and retired his number in 2021. He was just the third Met player to have his number retired.
Koosman is survived by three children and four grandchildren.
