Jerry Koosman, a key member of the 1969 New York Mets team that won the franchise's first World Series championship, has died at the age of 83. The left-handed pitcher passed away on November 1, 2026.
Koosman was one of the anchors of the "Miracle Mets" rotation alongside Tom Seaver. He won 17 games during the 1969 regular season and earned two victories in the World Series against the Baltimore Orioles, including a complete-game shutout in Game 2 and the clinching win in Game 5.
The Minnesota native spent 12 seasons with the Mets from 1967 to 1978, compiling a 140-137 record with a 3.09 ERA in New York. He was a two-time All-Star and finished second in the 1968 National League Rookie of the Year voting.
Koosman later pitched for the Minnesota Twins, Chicago White Sox, and Philadelphia Phillies before retiring in 1985 with 222 career victories.
