The Mets will retire Jerry Koosman's No. 36 during the 2020 season, COO Jeff Wilpon announced on Tuesday at Citi Field, with the exact date of the ceremony to be announced in the coming weeks.
Koosman joins Tom Seaver (No. 41) and Mike Piazza (No. 31) as the only Mets to have their number retired. The Mets have also retired manager Casey Stengel's No.37, manager Gil Hodges' No. 14, and Jackie Robinson's No. 42 -- as MLB did in unison in 1997.
Asked whether the retirement of Koosman's number means the Mets will be retiring other numbers in the future, Wilpon said "we have a plan to catch up."
David Wright's No. 5, Gary Carter's No. 8, and Keith Hernandez's No. 17 are some other numbers that come to mind when it comes to potential retirement of them.
"The excitement of playing for the Mets when we won the 1969 World Series was an experience I never thought I'd be able to repeat," Koosman said in a press release. "But the news that the Mets Hall of Fame Committee has voted to retire my number is another life-changing thrill and honor."
Koosman was on the mound at Shea Stadium when the Mets won the 1969 World Series in Game 5 against the Orioles.
During his Mets career from 1967-1978, Koosman started 346 games (completing 108 of them) while posting a 3.09 ERA and 1.21 WHIP and striking out 1,799 batters.
"Jerry is one of the most iconic Mets of all-time and this forever honor is a tremendous representation of what he meant to the organization," Wilpon said.
Koosman, who retired in 1985, said "it was privilege to play alongside some of the most wonderful and talented teammates for more than 11 years and to hone my craft under Gil Hodges."
"This honor isn't only for me and my family, it's for the legions of fans I grew to love," Koosman continued. "To know that my number will be retired and sit alongside other team legends is one of the greatest tributes I could ever be granted. I was always proud to be a Met. Today, I am even prouder."
