Jerry Koosman, Legendary Pitcher for the 1969 Miracle Mets, Dies at 83
The celebrated southpaw secured two victories in the 1969 World Series and spent 12 seasons with the New York franchise.
Jerry Koosman, a cornerstone of the New York Mets' historic 1969 championship team and one of the most accomplished pitchers in franchise history, died on Sunday at the age of 83. The Mets organization announced his passing, prompting tributes from club leadership and former teammates who remembered him as a fierce competitor and a beloved pillar of the team.
Mets owners Steve and Alex Cohen stated, 'Kooz was one of the greatest pitchers in team history and a beloved member of the Mets family.' They added that his legendary performances during the World Series helped secure the franchise's first championship, extending condolences to his family, friends, and former teammates.
Born on December 23, 1942, in Appleton, Minnesota, Koosman carved out a distinguished 19-year Major League Baseball career playing for the Mets, Minnesota Twins, Chicago White Sox, and Philadelphia Phillies. Over his 12 seasons with New York from 1967 to 1978, he accumulated a 3.09 ERA and 1.22 WHIP across more than 2,500 innings, establishing himself firmly as a franchise great.
Koosman's status as a big-game pitcher was cemented during the 1969 Fall Classic against the Baltimore Orioles. After teammate Tom Seaver lost the opener, Koosman pitched 8 2/3 innings to win Game 2 and later delivered a complete-game victory in Game 5 at Shea Stadium to clinch the title. He finished his postseason career with a 4-0 record and a 3.79 ERA across seven games.
Operating often in the shadow of teammate Tom Seaver, Koosman was nevertheless vital to the team's success. Former Mets teammate Ron Swoboda noted, 'None of us who are wearing World Series rings would be wearing World Series rings from 1969 if we didn’t have Jerry Koosman coming right behind Tom Seaver. You needed that 1-2 punch.' Catcher Duffy Dyer praised Koosman's formidable fastball, remarking that it was exceptionally tough for hitters to track because of its unpredictable movement.
Throughout his career, Koosman earned two All-Star selections in 1968 and 1969, finished second in National League Rookie of the Year voting behind Johnny Bench in 1968, and finished runner-up to Randy Jones for the NL Cy Young Award in 1976 after posting a career-high 21 wins. He finished his major league career with 222 wins, 2,556 strikeouts, and a 3.36 career ERA.
The Mets inducted Koosman into the team's Hall of Fame in 1989 and officially retired his uniform number 36 on August 28, 2021. Reflecting on the honor prior to his ceremony, Koosman expressed deep humility, saying he was thankful that the organization thought so highly of him.
