Jerry Koosman, the legendary lefty who helped the Mets win their first World Series title in 1969, died Sunday morning, the Mets said.
He is 83 years old.
Jay Horwitz said Koosman was battling multiple illnesses at the time.
He was surrounded by family in Osceola, Wisconsin.
Koosman was the winning pitcher in Game 2 of the 1969 World Series for the Orioles, and he also won the decisive Game 5 victory.
Koosman, a two-time All-Star whose No. 36 jersey has been retired by the Mets, had a 3.09 regular-season ERA in 12 seasons with the club.
He also played for the Twins, White Sox and Phillies.
